Signs You Need a Replacement

If your equipment is showing any of these symptoms, the fuel pump may be the cause:

• Primer bulb stays flat — The internal check valves are worn and can’t pull fuel from the tank. Replace the primer pump to restore fuel flow.
• Air bubbles in the fuel line — A worn primer pump allows air to enter the system through the shaft seal or housing crack.
• Engine hard to start after filter change — After replacing the fuel filter, the system needs to be primed. If the primer bulb doesn’t firm up, the pump is likely faulty.

Bleeding the System

After installing the new primer pump, pump the bulb until it becomes firm. Crack open the fuel line at the engine end and pump until fuel flows out bubble-free. Tighten the fitting and pump the bulb a few more times to confirm it stays firm. Start the engine and let it idle for a minute. If the primer bulb goes soft after the engine stops, check for air leaks at all connections.
