What This Part Helps Address

• Hard starting caused by a weak or failing in-tank fuel pump

• Fuel delivery loss under load or at higher demand
• Fuel leaks at the tank module seal or O-ring interface
• Poor pump pickup from a damaged or missing strainer

Installation Notes

PN4001 installs inside the fuel tank and uses a quick-connect outlet and pin-style electrical terminals. Verify tank condition, connector condition, and line routing before installation. Replace the seal and lock ring during service, and confirm the float arm moves freely after assembly. Use the included instruction sheet for installation reference.
