8mm (5/16") Hand Primer Bulb For Outboard Marine Boat Fuel Line – Universal Gas Pump

Got an older boat or need a spare primer bulb for your outboard?

This unbranded hand primer bulb is a simple, reliable replacement.

It's got a standard 8mm (that's 5/16 inch) pump interface, so it'll fit most common marine fuel lines.

It's brand new and made from a durable alloy and rubber combo.

Just squeeze it a few times to prime the fuel system before you start the engine.

Hose not included—just the bulb itself.

Keep this in your onboard toolbox as a backup, or replace that old stiff one that's cracking.

Simple part, but it'll save you a headache on the water!
