Steps
Drain the fuel conditioning module
Work in a ventilated area away from ignition sources and collect fuel in an approved container. Open the module water-separator drain and allow the module to drain, then close the drain.
Disconnect pump wiring
Locate the fuel conditioning module on the driver-side frame rail. Disconnect the lift-pump electrical plug and the water-sensor connector, releasing locks without crushing the plugs. Move the harness clear.
Remove and replace the pump
Remove the lift pump from the module using the correct socket and carefully withdraw it. Check the sealing surface, fit the replacement and seal as specified, and secure it without overtightening.
Reconnect and inspect
Reconnect both electrical connectors and restore the harness routing. Close the drain, prime the fuel system using the vehicle procedure, then start and inspect the module for leaks.
Check your vehicle’s repair manual for exact specifications and fit.
