How to Order Bulk Fuel Hose

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

For example, if your fuel-system layout requires 10 feet of hose, order a quantity of 10.

What is Type A Marine Fuel Hose?

Type A marine fuel hose is designed for installations requiring the additional fire-resistant protection associated with the Type A classification.

It is commonly used in enclosed and below-deck fuel-system routing and in other locations where Type A hose is specified by the boat builder, engine manufacturer or applicable installation requirements.

Fuel hose should always be selected based on both hose diameter and installation type.

Complete Your 3/8" Fuel Line Setup

Pro Marine stocks the matching clamp, primer bulb and Oetiker installation tools needed to build or service a 3/8" marine fuel-line assembly.

3/8" Type B Alternative

3/8" Type A vs. Type B Fuel Hose

Fuel Hose	Classification	Matching Clamp	Primer Bulb
375-1	Type A	Oetiker 4-185	Pro Marine 8005 - 3/8"
375	Type B	Oetiker 4-185	Pro Marine 8005 - 3/8"

Same Clamp for Both 3/8" Fuel Hoses

Both the 375-1 Type A and 375 Type B 3/8" fuel hoses use the same Oetiker 4-185 ear clamp.

That makes clamp selection simple when changing between these two 3/8" hose types. The main consideration is the required fuel-hose classification for the installation.

What This Fuel Hose is Used For
