As with any vehicle more than 20 years old, you should maintain the engine assembly on your 1990 Ford Ranger and repair it as needed. If you do not replace a damaged fuel pump, it will have a detrimental effect on your engine as the fuel will no longer be able to move around the engine. You can purchase replacement parts and tools from an auto supply store.

Tools Used[edit]

Wrench set
Replacement fuel pump
Car jack
Drain pan

Change the Fuel Pump[edit]

  • Enter the driver's side of the Ranger and release the lever to open the hood of the vehicle. Disconnect the negative terminal from the battery.
  • Pry the drain plug off of the fuel tank with a flathead screwdriver. Place a drain pan underneath the tank and drain the fuel into the pan. Replace the plug on the tank.
  • Place a car jack underneath the vehicle so that it sits directly underneath the fuel tank. Remove the four bolts which hold the two straps below the fuel tank in place with a wrench. The fuel tank will then rest halfway out of the vehicle on the jack.
  • Remove the fuel lines and electrical connectors with your hands. You should be able to pull them from their connections. Remove the two mounting bolts which fix the fuel pump to the top of the fuel tank with a wrench. Lift the pump away from the tank.
  • Attach the O-ring top to the base of the new pump. Fix the fuel pump to the top of the fuel tank with the mounting bolts. Attach the fuel tank and its connectors back into the vehicle following the removal steps in reverse.
  • Place the fuel back into the fuel tank and attach the negative terminal back onto the battery. Turn on the engine and check that the fuel pump works correctly.
