How to Change the D150 Fuel Pump


The Dodge D150 was a full-sized pickup truck that began to be known as the Ram beginning in 1981. The 1993 D150 came with either a 3.9-liter, 180 horsepower six-cylinder engine or a 5.2 liter, 230 horsepower eight-cylinder engine. All models came standard with anti-lock brakes and a five-speed manual transmission. Each of these trucks models were equipped with an electric fuel pump that must be replaced when it fails to function. It is important to follow the proper procedures when changing the fuel pump so that the fuel system of your D150 truck is not damaged.

Things You'll Need

  • Gas can

  • Siphon
  • Siphon hose
  • Jack
  • Jack stands
  • Hammer
  • Brass punch
  • Ignition key
  • Flathead screwdriver
  • Socket wrench
  • Pliers
  • Wrench
  • Towels
  • Wheel blocks

Prepare the Truck For the Repair

  • Relieve the fuel pressure in the truck’s fuel system by removing the gas tank cap. Remove the battery cables from the battery with a wrench and pliers.

  • Siphon out the fuel sitting in the truck’s fuel tank. Put the fuel into a gas can with a funnel. Keep heavy mechanic's towels available around the gas can in case you spill any fuel.

  • Lift the rear portion of the truck with a jack and jack stands to have easier access to the fuel tank. Put wheel blocks behind the front two wheels to protect yourself while you are underneath the truck.

  • Detach the gas tank filler tube from the gas tank. Depending on the screws holding the filler tube in place, you will need either a socket wrench or flathead screwdriver to complete this step.

  • Disconnect the fuel lines running to the top of the fuel pump. You can remove these lines by hand unless there is some corrosion at the connection point. If you encounter any difficulty removing the lines, pull them away from the pump with pliers.

Detach the Gas Tank and Replace the Old Pump

  • Hold up the bottom of the gas tank with your hand while you remove the metal support straps holding the tank in place. Check the tank after you have detached it from the truck to see if there are any cracks, rust or damage that would necessitate replacing the tank.

  • Pull the fuel tank out from under the truck to begin replacing the old fuel pump.

  • Disconnect the fuel pump locking ring from the top of the gas tank with a hammer and brass punch. Pull the old fuel pump and its strainer from the gas tank.

  • Clean the surface around the gas tank where the fuel pump and fuel pump locking ring sit. Wipe away any dirt or other debris that has accumulated with a towel.

  • Place the new fuel pump and strainer inside the gas tank. Place the locking ring back onto the tank and tighten the ring with a hammer and brass punch.

Prepare the Truck to Drive

  • Reattach the gas tank to the truck by attaching the metal straps around it. Reattach the fuel lines that run into the top of the fuel pump and connect the gas tank filler tube back to the tank.

  • Lower the rear portion of the truck and reconnect the battery cables you had disconnected.

  • Put fuel back into the truck and start it. Check to see if there are any leaks in the fuel lines under the vehicle.
