Installation Notes and Tips

Verify inlet and outlet orientation before installation, and confirm the 5/8"-18 threaded outlet matches the existing fuel line connection. Replace the gasket during service, inspect the mounting surface for damage, and check fuel pressure after installation to confirm the pump is operating within the 7 to 9 psi range. Use the included instruction sheet as a reference during installation.
