Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is cool. Work in a well-ventilated area.
2. Relieve Fuel Pressure: Carefully loosen the fuel filter or use the recommended procedure for your engine to relieve any pressure in the fuel lines.
3. Disconnect Lines: Place a rag under the fuel pump to catch drips. Note the orientation of the fuel inlet, outlet, and pulse lines, then carefully disconnect them.
4. Remove Old Pump: Unbolt and remove the old fuel pump from the engine block.
5. Clean Surface: Clean the mounting surface on the engine, removing any old gasket material or sealant.
6. Install New Pump: Place the new gasket on the engine block and mount the new fuel pump. Hand-tighten the bolts first, then torque them to the manufacturer's specification.
7. Reconnect Lines: Securely attach the fuel inlet, outlet, and pulse lines to the correct ports on the new pump.
8. Final Checks: Reconnect the battery. Prime the fuel system if necessary. Start the engine and carefully inspect for any fuel leaks around the pump and its connections.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump will fit my engine?

A: Start by checking the compatible engine model chart on this page. Cross-reference your engine's horsepower, model, and year. Most importantly, verify that your existing fuel pump's OEM part number matches one of the numbers listed in our cross-reference table (e.g., 438556, 433387, 18-7352).

Q: Is this pump for VRO (oil-injection) systems?

A: No. This is a non-VRO style fuel pump. It is designed specifically for engines that do not have an oil injection system and require pre-mixed fuel.

A: Common symptoms include the engine sputtering at high speeds, a general loss of power, difficulty starting, or the engine stalling. These issues often indicate the pump can no longer supply adequate fuel pressure.
