🔧 Fuel Pump - Replacement

Assumption: On your Explorer, the fuel pump module is serviced by lowering the fuel tank. There is no separate easy-access pump hatch for this repair.

This job requires relieving fuel pressure, supporting the tank, disconnecting the fuel lines and wiring, then lowering the tank to replace the in-tank pump module. Work slowly and keep sparks, flames, and hot tools away from the fuel system.

Difficulty Level: Advanced | Estimated Time: 4-6 hours
