Chrysler Force Fuel Hose

Shop fuel hose for Chrysler Force outboards. Marine-rated fuel hose is critical for safe, consistent fuel delivery and helps prevent leaks, air intrusion, and fuel starvation—especially with today’s ethanol-blended fuels.

Why Replace Fuel Hose?

  • Prevents fuel leaks and cracking from age or ethanol exposure
  • Reduces risk of air leaks that cause hard starting and stalling
  • Maintains proper fuel flow under load
  • Helps avoid soft, collapsing hose that restricts fuel delivery

Common Signs of Bad Fuel Hose

  • Fuel smell in the boat or around the motor
  • Visible cracking, swelling, or soft spots in the hose
  • Engine bogging, surging, or dying at higher RPM
  • Primer bulb won’t stay firm or repeatedly loses prime

Choosing the Correct Tygon Hose Size

Tygon hose should be matched to the fitting and fuel-system application. Item 257 has a 1/4" inside diameter.

Do not substitute a 3/16" or 5/16" hose simply because the fitting appears close in size. The hose must fit the fuel-system connection properly and match the original application.

When Should Tygon Fuel Hose Be Replaced?

Inspect small fuel lines during normal fuel-system maintenance. Replace hose that shows signs such as:

  • Cracks or splitting
  • Hardening or brittleness
  • Fuel leakage
  • Loose hose-to-fitting connections
  • Severe discoloration or deterioration
  • Abrasion or routing damage

Transparent Tygon Hose

3/32" Tygon Small Oil Injection Hose - 10ft Length

Pro Marine Item 255 is transparent 3/32" Tygon hose supplied in a 10-foot length. This small-diameter flexible tubing is commonly used for PWC oil-injection line applications where 3/32" inside-diameter hose is required.

Need another size? Pro Marine stocks a range of Tygon hose from 3/32" through 5/16", including fuel-hose and bleed-hose options. See the complete size chart below.

3/32" Tygon Hose - Item 255

Inside Diameter: 3/32"
Length: 10 Feet
Material: Tygon
Color: Transparent
Primary Application: PWC Small Oil Injection Line
Item Number: 255

What This Tygon Hose is Used For

Item 255 is intended for small-diameter fluid-line applications requiring 3/32" Tygon tubing. Pro Marine lists this hose primarily for PWC small oil-injection line applications.

Small oil-injection hoses can become hard, brittle, cracked or damaged with age. Replacing deteriorated tubing is an important part of servicing an oil-injected PWC or other compatible system.

Always verify the required inside diameter and application before replacing an existing hose.

Why Use Transparent Tygon Hose?

Transparent tubing provides an important advantage on small fluid lines: it allows the technician to visually inspect what is happening inside the hose.

Depending on the system, this can make it easier to check for fluid in the line and identify obvious air pockets or contamination during service.

Reinforced 2" Fuel Hose from Deck Fill to Marine Fuel Tank

Marine Fuel Tank Fill Hose

2" Type A2 Marine Fuel Fill Hose - FILLHOSE-2

FILLHOSE-2 is a 2" marine Type A2 fuel fill hose designed for the large-diameter fuel connection between a boat's deck-mounted fuel fill and permanent fuel tank.

This hose is used during refueling to carry gasoline from the deck fill down to the tank. It is different from the smaller fuel-supply hose that carries fuel from the tank to the engine.

Pro Marine also stocks the matching 4-9 German-style hose clamp and a smaller 1-1/2" Type A2 fuel fill hose for installations using 1-1/2" fittings.

2" Marine Fuel Fill Hose - FILLHOSE-2

Inside Diameter: 2"
Hose Type: USCG Type A2
Application: Marine Fuel Fill Line
Connects: Deck Fuel Fill to Fuel Tank
Matching Clamp: 4-9

What This Fuel Fill Hose is Used For

FILLHOSE-2 is intended for the fuel-fill section of a permanently installed marine fuel system.

In a typical installation, the hose connects the fitting underneath the deck-mounted gas fill to the fill neck on the fuel tank.

Common applications include:

  • Boat fuel tank fill hose
  • Deck fill to fuel tank plumbing
  • Replacement of old or deteriorated fuel fill hose
  • Boat restoration and fuel-system rerigging
  • New permanent marine fuel-tank installations

What Does Type A2 Fuel Hose Mean?

Type A2 is a marine fuel-hose classification commonly used for fuel fill and vent applications.

The Type A designation indicates a hose intended for marine fuel systems where fire resistance is required. The A2 classification is used for specific fill and vent applications rather than the smaller engine fuel-feed line.

For this product, the important point is that it is designed as a large-diameter marine fuel fill hose.

Fuel Fill Hose is Different from Engine Fuel Hose

This 2" hose is intended for the deck fill to fuel tank connection.

Do not use hose diameter alone to choose a marine fuel hose. Fuel fill, vent and engine supply lines have different applications and requirements.

This deck fill is not the matching 2" connection for FILLHOSE-2, but it is available for installations using the smaller 1-1/2" hose system.

View 1-1/2" Chrome Gas Deck Fill

How a Marine Fuel Fill System Works

The fuel-fill system provides the path from the deck-mounted fuel cap to the boat's permanent fuel tank.

During refueling:

  1. Fuel enters through the deck fill.
  2. The fuel travels through the large-diameter fill hose.
  3. The hose delivers the fuel to the tank's fill connection.
  4. The tank's separate vent system allows displaced air to escape.

The deck fill, fuel fill hose, tank connection and vent system all need to be correctly sized and routed for reliable filling.

Fuel Fill Hose Installation Tips

  • Verify the deck-fill and tank-fill connection size before ordering hose.
  • Use hose specifically rated for marine fuel-fill service.
  • Make sure the hose fully seats over each hose barb or fitting.
  • Use properly sized corrosion-resistant clamps.
  • Avoid tight bends and kinks that can restrict fuel flow.
  • Plan the routing before cutting the hose.
  • Keep the hose away from sharp edges and moving parts.
  • Do not allow batteries or stored equipment to crush the hose.
  • Check both ends for leaks or seepage after installation.
Measure Before Ordering

A 2" fuel fill hose requires compatible 2" fittings.

If the deck fill or fuel-tank fill neck is 1-1/2", use the corresponding 1-1/2" hose instead of trying to force or adapt the wrong hose size.

Why Fuel Fill Hose is So Heavy Duty

Fuel fill hose is much larger and more heavily constructed than the smaller fuel hose used to feed an engine.

It has to handle:

  • Large volumes of fuel during refueling
  • Marine vibration and movement
  • Fuel exposure
  • Heat and environmental exposure
  • The bends required between the deck fill and fuel tank

Because of its construction, fuel fill hose can be relatively stiff. Planning the routing before installation is especially important.

When Should Fuel Fill Hose Be Replaced?

Inspect the fill hose whenever the deck fill, fuel tank or surrounding rigging is serviced.

Replace the hose if you find:

  • Cracks in the outer surface
  • Hard, dry or brittle rubber
  • Soft or swollen areas
  • Abrasion or chafe damage
  • Fuel seepage
  • Persistent gasoline odor near the hose
  • Loose, damaged or corroded clamps
  • A hose that no longer fits tightly on the fittings

Key Features and Benefits

  • 2" marine fuel fill hose
  • Type A2 construction
  • Designed for deck-fill to fuel-tank plumbing
  • Large-diameter marine fuel-system application
  • Matching 4-9 German-style clamp available

This is the Type B version, commonly used in exposed and above-deck marine fuel-line applications where Type B hose is permitted.

Pro Marine also stocks the matching Oetiker 4-133 clamp, Pro Marine 8002 1/4" primer bulb, Oetiker installation tools and a 1/4" Type A fuel hose option.

1/4" Bulk Marine Fuel Line

Inside Diameter: 1/4"
Manufacturer: MPI Products
Fuel Hose Type: Type B Marine Fuel Hose
Sold: By the Foot
Recommended Clamp: Oetiker 4-133
Recommended Primer Bulb: Pro Marine 8002 - 1/4"

How to Order Bulk Fuel Hose

This fuel hose is sold by the foot. Enter the quantity based on the continuous hose length required for your installation.

For example, if your fuel-line run requires 6 feet of hose, order a quantity of 6.

Type B Marine Fuel Hose

Marine fuel hose classifications identify how the hose is intended to be used within a boat's fuel system.

Type B fuel hose is commonly used for exposed or above-deck applications where that hose classification is appropriate. It does not carry the same additional fire-test classification as Type A marine fuel hose.

If your fuel line passes through an enclosed area or the installation specifically requires Type A hose, use the Type A option linked below.

Need Type A Fuel Hose?

For installations requiring the additional Type A fire-resistant classification, use the MPI 314-1 1/4" Type A fuel hose.

MPI 314-1 Type A Oetiker 4-170 Pro Marine 8002 - 1/4"

Why Do Two 1/4" Hoses Use Different Clamps?

The 1/4" measurement refers to the hose's inside diameter. It does not determine the outside diameter of the hose.

Type A and Type B hose use different constructions and wall thicknesses, so their outside diameters can be different even when both have a 1/4" inside diameter.

That is why the MPI 315-014 Type B hose uses Oetiker 4-133, while the MPI 314-1 Type A hose uses Oetiker 4-170.

What This Fuel Hose is Used For

MPI 315-014 1/4" Type B fuel hose can be used for building, replacing or repairing marine fuel lines where 1/4" hose and a Type B classification are appropriate.

Because this hose is sold in bulk by the foot, it can be paired with the correct primer bulb, fittings and clamps to create a custom-length fuel-line assembly.

Building a 1/4" Outboard Fuel Line

A typical 1/4" outboard fuel-line assembly may require:

  • MPI 315-014 1/4" Type B marine fuel hose
  • Pro Marine 8002 1/4" primer bulb
  • Correct tank-side fitting or connection
  • Correct engine-side fitting or connector
  • Oetiker 4-133 ear clamps
  • Oetiker pincer installation tool

The exact components required depend on the engine, fuel tank and overall fuel-system layout.

Primer Bulb Selection

Primer bulb fittings should match the inside diameter of the fuel hose. For this 1/4" hose, use the Pro Marine 8002 1/4" Primer Bulb.

View Pro Marine 8002 1/4" Primer Bulb

5/16" Bulk Marine Fuel Line

Inside Diameter: 5/16"
USCG Rating: Type B1/B2
Manufacturer: MPI Products
Color: Black
Sold: By the Foot
Recommended Clamp: Oetiker 4-153
Recommended Primer Bulb: Pro Marine 8004 - 5/16"

How to Order Bulk Fuel Hose

This hose is sold by the foot. Select the quantity based on the total continuous length of hose required for your installation.

For example, if you need approximately 8 feet of fuel hose, order a quantity of 8.

What Does USCG Type B1/B2 Fuel Hose Mean?

Marine fuel hose classifications help identify where and how a hose is designed to be used within a boat's fuel system.

The "B" designation identifies marine fuel hose that does not carry the same USCG fire-test requirement as Type A hose. For that reason, Type B hose is commonly associated with exposed or above-deck fuel-line installations, while Type A hose is the appropriate choice where the installation requires the additional fire-resistant Type A classification.

The numbers "1" and "2" refer to fuel permeation performance. Type 1 is the lower-permeation classification and is the classification normally associated with fuel-feed hose intended to contain fuel continuously. Type 2 permits greater permeation and is used for applications such as certain fill and vent arrangements.

Quick Guide: Type A vs. Type B Marine Fuel Hose
Fuel Hose Type General Use Fire-Test Requirement
Type A1 Fuel-feed applications including installations requiring Type A protection Yes
Type A2 Certain fill and vent applications requiring Type A protection Yes
Type B1 Fuel-feed applications where Type B hose is permitted No Type A fire-test rating
Type B2 Certain fill and vent applications where Type B hose is permitted No Type A fire-test rating
Need Fuel Hose for an Enclosed or Below-Deck Installation?

Do not choose fuel hose based on diameter alone. The required USCG hose classification depends on where and how the hose is installed.

For installations requiring Type A1/A2 marine fuel hose, use our 5/16" Type A fuel hose instead.

Mercury OEM 5/16" Fuel Hose Available

Mercury OEM 5/16" Silver Fuel Hose

Prefer the Mercury factory fuel hose? Pro Marine also stocks Mercury OEM 5/16" silver fuel hose sold by the foot.

The Mercury hose uses a different outside diameter than this MPI hose and therefore requires a different Oetiker clamp: 4-145.

View Mercury OEM 5/16" Fuel Hose

View Oetiker 4-145 Clamp for Mercury Fuel Hose

Why Doesn't Every 5/16" Fuel Hose Use the Same Clamp?

5/16" identifies the hose's inside diameter, not its outside diameter. Different hose constructions can have different wall thicknesses and therefore different outside diameters.

That is why this MPI 315-056 Type B hose uses Oetiker clamp 4-153, while the Mercury OEM 5/16" silver hose uses Oetiker clamp 4-145.

Always match the clamp to the specific hose being installed rather than selecting a clamp based only on the hose's inside diameter.

What This Fuel Hose is Used For

This 5/16" bulk marine fuel hose can be used when building, repairing or replacing fuel lines in compatible marine applications where USCG Type B hose is appropriate.

Selling the hose by the foot allows boat owners and marine technicians to build the required length and add the appropriate primer bulb, connectors, fittings and clamps for the specific installation.

Building a 5/16" Outboard Fuel Line

A typical 5/16" outboard fuel-line setup may require:

  • 5/16" marine fuel hose
  • 5/16" primer bulb
  • Correct engine-side fuel fitting or connector
  • Correct tank-side fitting or connection
  • Correctly sized Oetiker ear clamps
  • Oetiker pincer tool for clamp installation

The exact components depend on the engine, fuel tank and layout of the boat's fuel system.

Key Features & Benefits

  • 5/16" inside diameter marine fuel hose
  • USCG Type B1/B2 rated hose

FAQ

What size is this fuel hose?
This hose has a 5/16" inside diameter.

Is the hose sold by the foot?
Yes. Order the quantity corresponding to the number of feet needed for your installation.

What does USCG Type B mean?
Type B marine fuel hose meets the applicable SAE marine fuel-hose performance classification but does not carry the same USCG fire-test requirement as Type A hose. It is commonly used in exposed or above-deck applications where Type B hose is permitted.

What is the difference between B1 and B2?
The number identifies the hose's permeation classification. Type 1 has the lower permeation limit and is normally associated with fuel-feed applications intended to contain fuel continuously. Type 2 allows greater permeation and is used for certain other fuel-system applications.

Can I use this hose below deck?
Fuel-hose requirements depend on the installation. For enclosed or below-deck installations requiring the Type A fire-resistant classification, use the 5/16" Type A fuel hose .

Which Oetiker clamp fits this hose?
Use the Oetiker 4-153 ear clamp with this MPI 315-056 hose.

Which primer bulb fits this hose?
The Pro Marine 8004 5/16" Primer Bulb is the matching hose size.

Do you sell a Mercury OEM 5/16" fuel hose?
Yes. Pro Marine stocks Mercury OEM 5/16" silver fuel hose by the foot. The Mercury hose uses Oetiker clamp 4-145 rather than the 4-153 clamp used with this MPI hose.

Why are there different clamps for two 5/16" hoses?
The 5/16" measurement refers to inside diameter. Hose outside diameter can vary depending on wall thickness and construction, so the correct Oetiker clamp must be matched to the specific hose.
