🔧 Fuel Pump - Replacement

This job replaces the in-tank fuel pump module. On your Land Cruiser, the safest full-service method is usually to lower the fuel tank and service the pump from the top of the tank if there is no factory access panel. Fuel is flammable, so work slowly and keep all sparks and heat away from the area.

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