1/2" Type A1 Marine Fuel Hose
MPI 360-12 1/2" Type A1 Marine Fuel Hose
The MPI 360-12 1/2" Type A1 Marine Fuel Hose is a heavy-duty bulk fuel line for marine fuel systems requiring a 1/2" inside diameter and the additional fire-resistant protection associated with Type A1 marine fuel hose.
The larger 1/2" inside diameter makes this hose suitable for higher-flow marine fuel-system applications where a larger supply line is required.
Pro Marine stocks the matching German-style hose clamp, installation tools and a complete clamp assortment for marine fuel-system service.
Inside Diameter: 1/2"
Manufacturer: MPI Products
Fuel Hose Type: Type A1
Application: Marine Fuel System
Matching Clamp: German-Style Hose Clamp 4-4
What is Type A1 Marine Fuel Hose?
Type A1 marine fuel hose is designed for fuel-feed applications requiring a marine hose with enhanced fire-resistant performance.
Type A1 hose is commonly used in permanent marine fuel systems and installations where the fuel line passes through enclosed or below-deck areas.
When selecting fuel hose, both the inside diameter and the required hose classification should be verified for the installation.
Why Use 1/2" Fuel Hose?
A 1/2" fuel line provides greater internal flow area than the more common 1/4", 5/16" and 3/8" marine fuel hoses.
It may be used in applications where the engine or fuel-system design requires a larger fuel supply line to support higher fuel-flow demand.
Always follow the engine or boat manufacturer's required hose diameter rather than increasing or decreasing hose size without verifying the fuel-system requirements.
Unlike many smaller outboard fuel-line assemblies, a 1/2" marine fuel-line system would not normally use an inline hand primer bulb.
Larger 1/2" fuel lines are generally associated with higher-flow fuel systems where fuel delivery is handled by the engine's fuel-system configuration rather than a manual primer bulb.
Always follow the fuel-system design specified for the engine and boat.
Matching Fuel Hose Clamp
German-Style Hose Clamp - 4-4
Recommended hose clamp for the MPI 360-12 1/2" Type A1 marine fuel hose.
German-style hose clamps provide a secure connection for larger marine fuel-hose applications.
Fuel Line Tools and Clamp Assortment
Oetiker Standard Jaw Pincer Tool
Useful installation tool for Oetiker ear clamps used throughout many marine fuel-line systems.
While this 1/2" hose uses the German-style clamp shown above, the pincer tool is useful when servicing other fuel-hose sizes that use Oetiker ear clamps.

Oetiker Clamp Pack with Tool
Complete assortment of common Oetiker clamp sizes with the installation tool included.
A convenient option for marine shops and technicians servicing different fuel-hose sizes throughout a boat or engine.
View Oetiker Clamp PackWhat This Fuel Hose is Used For
MPI 360-12 is used when building, repairing or replacing a marine fuel supply line requiring 1/2" Type A1 hose.
Typical applications involve larger marine fuel systems where increased fuel-flow capacity is required and the installation calls for Type A1 hose.
Typical 1/2" Fuel-Line Setup
Depending on the boat and engine, a 1/2" marine fuel-line installation may include:
- MPI 360-12 1/2" Type A1 marine fuel hose
- German-style 4-4 hose clamps
- Fuel tank pickup or shutoff valve
- Fuel/water separator or filter assembly
- Engine fuel-system connection
- Application-specific fittings and adapters
Primer Bulb vs. Larger Fuel Systems
Smaller outboard fuel systems commonly use 1/4", 5/16" or 3/8" hose with an inline primer bulb.
A 1/2" fuel supply line generally indicates a higher-flow fuel system, and a hand primer bulb is not normally part of that configuration.
The engine manufacturer's fuel-system requirements should always take priority when determining hose size, fittings, filters and priming components.
Fuel Hose Size Comparison
| Hose ID | Typical Pro Marine Fuel-Line Options | Primer Bulb Available |
|---|---|---|
| 1/4" | Type A / Type B | Yes - Pro Marine 8002 |
| 5/16" | Type A / Type B / Mercury OEM | Yes - Pro Marine 8004 |
| 3/8" | Type A / Type B | Yes - Pro Marine 8005 |
| 1/2" | Type A1 - MPI 360-12 | Normally not used |

FAQ
What size is MPI 360-12?
This fuel hose has a 1/2" inside diameter.
What type of fuel hose is 360-12?
It is Type A1 marine fuel hose.
What is Type A1 fuel hose used for?
Type A1 is used for marine fuel-feed applications requiring the additional
fire-resistant performance associated with Type A hose.
Can this hose be used below deck?
Type A1 hose is commonly used in enclosed and below-deck fuel-system
installations when the fuel system calls for this hose size and classification.
Which clamp fits this 1/2" hose?
Use the
German-Style 4-4 Hose Clamp
.
Does this hose use an Oetiker ear clamp?
The recommended clamp for this hose is the
German-style 4-4 hose clamp.
Does 1/2" fuel hose use a primer bulb?
A primer bulb is not normally used in a fuel system
requiring 1/2" hose. Larger lines are typically used in higher-flow fuel
systems with a different priming and fuel-delivery arrangement.
Should I use 1/2" hose just to increase fuel flow?
Use the hose diameter specified for the engine and fuel system. Increasing
hose size without verifying the complete system is not a substitute for
following the manufacturer's fuel-system requirements.
Do you sell fuel-line clamp tools?
Yes. Pro Marine stocks the
Oetiker Standard Jaw Pincer Tool
for fuel-line applications using Oetiker ear clamps.
Do you sell a complete clamp assortment?
Yes. The
Oetiker Clamp Pack with Tool
includes commonly used clamp sizes and an installation tool.
