Ford 1L2Z-9H307-GA Sender And Pump Assembly

This special tool becomes necessary to disconnect fuel lines in all models starting with 2001. You can find the tool at regular auto part shops; some machines have it already built-in about 10 inches after the fuel filter. Experts recommend that you replace the fuel pump and sender one piece together. Make sure to remove remaining fuel from the tank with a hand pump before you can take apart the fuel pump. First, bring fuel pressure down. Then disconnect the negative side of the battery and place four blocks under the car to lift it off the ground. Pull the fuel tank away from the car. Disconnect both the incoming fuel and return systems from the pump unit. To take the fuel pump units off older models, tap their lock ring counterclockwise with a brass punch or wood dowel until loose, remove the mounting bolts, and use pliers or a strap wrench to carefully remove the plastic retaining ring around the assembly. When you lift the fuel pump/sending unit assembly out of the tank, check the O-ring condition. Replace it when you see signs of extreme dryness, damage, or wear. Take off the fuel pump mounting clamp bolt, then disconnect the lower clamp of the fuel hose and electrical connection to take the fuel pump apart from the assembly. Replace the filter at the bottom of the fuel pump when its time. Changing the assembly involves cleaning the place it mounts and putting grease on the seal ring before setting it back in place. Slide the O-ring into place around the tank opening, slide the entire assembly into the tank, and use your hand to turn the lock ring clockwise on older models until it clicks fully into place. Fit the fuel pump's marks to the tank's marks. Place the tank bolts, tighten them, and install everything back in reverse.

The initial steps include relieving fuel pressure, disconnecting the battery, and raising and securely supporting the vehicle on jackstands.

Relieve fuel pressure, disconnect the fuel pressure gauge, and start the engine to verify the absence of fuel leaks. Relieving fuel pressure is crucial for safety during any work on the fuel system.
