Genuine Mercury Marine Bulk Fuel Hose
Mercury OEM 5/16" Silver Fuel Hose - Sold by the Foot
This Mercury OEM 5/16" silver fuel hose is a genuine Mercury Marine bulk fuel line for building, repairing or replacing 5/16" fuel-hose assemblies on compatible Mercury outboard applications.
The hose is sold by the foot, allowing you to purchase the length needed for your boat instead of being limited to a preassembled fuel-line length.
Pro Marine also stocks the correct Oetiker 4-145 ear clamp, a compatible 5/16" primer bulb, Oetiker installation tools and alternative marine fuel hose for Type A and Type B applications.
Brand: Mercury Marine
Type: Genuine Mercury OEM Fuel Hose
Inside Diameter: 5/16"
Color: Silver
Sold: By the Foot
Recommended Clamp: Oetiker 4-145
Recommended Primer Bulb: Pro Marine 8004 - 5/16"
How to Order Mercury Bulk Fuel Hose
This Mercury fuel hose is sold by the foot. Enter the quantity based on the continuous length of hose needed for your installation.
For example, if you need 6 feet of fuel line, order a quantity of 6.
Genuine Mercury Marine Fuel Hose
This hose is an OEM option for customers who prefer to use Mercury Marine fuel hose when servicing or building a Mercury outboard fuel-line system.
Its 5/16" inside diameter allows it to be paired with compatible 5/16" fuel-system components, including the Pro Marine 8004 primer bulb.
The 5/16" measurement refers to the hose's inside diameter. Different 5/16" fuel hoses can have different wall thicknesses and outside diameters.
This Mercury silver fuel hose uses the Oetiker 4-145 ear clamp. Do not substitute the 4-153 clamp used with our MPI 315-056 5/16" Type B hose simply because both hoses have a 5/16" inside diameter.
