Transparent Tygon Bleed Hose
1/8" Tygon Bleed Hose - 10ft Length
Pro Marine Item 259 is transparent 1/8" Tygon bleed hose supplied in a 10-foot length. It is used in compatible marine and PWC applications requiring small-diameter bleed line.
The transparent construction makes it easy to visually inspect fluid inside the hose, which is especially useful when servicing bleed, oil-related or other small fluid-line circuits.
Pro Marine also stocks several other Tygon hose sizes for fuel, oil-injection and bleed-line applications. Use the size chart below to compare the available options.
Inside Diameter: 1/8"
Length: 10 Feet

Color: Transparent
Application: Bleed / Small Fluid Line
Item Number: 259
What This Tygon Bleed Hose is Used For
Item 259 is intended for small-diameter marine applications requiring 1/8" transparent Tygon bleed hose.
Small bleed lines can become brittle, cracked, loose or damaged over time. Replacing deteriorated tubing helps maintain proper fluid routing and system operation.
Always verify the required inside diameter and application before replacing an existing hose.
Why Use Transparent Bleed Hose?
Transparent hose allows the line and the fluid inside it to be visually inspected during service.
Depending on the system, this can make it easier to identify:
- Whether fluid is present in the line
- Air pockets
- Visible contamination
- Flow interruptions
- Hose discoloration or deterioration

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.
The transparent construction makes it easier to visually inspect the line and see fluid within the hose, which is particularly useful when servicing small oil-injection systems.
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.
Inside Diameter: 3/32"
Length: 10 Feet

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.
Pro Marine stocks multiple transparent Tygon hose sizes for PWC, outboard, fuel-line, oil-injection and bleed-hose applications.

View Oetiker Clamp PackChoosing the Correct Tygon Hose Size
Hose size should be matched to the fitting and system being serviced. Do not substitute a larger or smaller hose simply because it appears close in size.
For an existing oil-injection, fuel or bleed-line system, compare the original hose size and application before replacement. If the application is uncertain, verify the engine or PWC model and the required hose size before installation.

MPI Type B Marine Fuel Hose
MPI 1/4" Marine Fuel Hose - Type B - Sold by the Foot
The MPI 315-014 1/4" Fuel Hose is bulk marine fuel line for applications using 1/4" inside-diameter hose. It is sold by the foot so boat owners and marine technicians can build the exact fuel-line length required for the installation.
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.
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.
For installations requiring the additional Type A fire-resistant classification, use the MPI 314-1 1/4" Type A fuel hose.

1/4" Fuel Hose Comparison
| Fuel Hose | Classification | Matching Clamp | Primer Bulb |
|---|---|---|---|
| MPI 315-014 | Type B | Oetiker 4-133 | Pro Marine 8002 - 1/4" |
| 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.

The 1/4" measurement is the inside diameter. Different hose construction
changes the outside diameter, so the clamp must be matched to the specific hose.
