Important – Check Your Fuel Hose Size

This primer bulb is designed for 8 mm / 5/16" fuel hose.

Please check the internal diameter of your existing fuel hose before purchasing.

Do not order based only on the appearance of your existing primer bulb.

If the part looks the same as yours, this does not always mean it is the correct one for your outboard or fuel system.

Check the fuel hose is 8 mm / 5/16" ID
Check the direction arrow on the bulb
Install with the arrow pointing towards the engine
Ensure the fuel hose is fully seated
Secure the hose using the supplied clamps
Check carefully for fuel leaks before operating the engine

Replace any fuel hose that is cracked, hardened, damaged or deteriorated.
