In-Tank Fuel Pumps

  1. Disconnect the negative battery terminal, open the fuel tank filler door and disconnect the sending unit feed wire. Release the fuel pressure.
  2. Siphon the fuel from the fuel tank. If the rear of the car is raised one foot higher than the front, more fuel can be taken out.
  3. Raise the rear of the car and remove the screw securing the ground wire to the cross member.
  4. Disconnect the fuel line, evaporative emission lines and the fuel return lines at the front of the tank.
  5. Support the tank with a jack and wooden block and remove one screw on each side securing the fuel tank support straps to the body at the front of the tank.
  6. Lower the jack and tank enough so that the fuel pump electrical lead can be disconnected. Disconnect the wire.
  7. Remove the fuel tank from the car.
  8. Remove the locknuts securing the fuel gauge tank unit and fuel pump feed wires to the tank unit.
  9. Turn the cam locking ring counterclockwise with a soft non-ferrous punch and hammer. When the lock ring is disengaged, remove it and lift the gauge/pump unit from the tank.
  10. Install in the reverse order of removal. Tighten the fuel tank retaining strap screws to 25 ft. lbs. (34 Nm).

I got a 1987 Cadillac sedan Deville and just put a new start on it it will start up and run great but if u turn it off it takes forever to start back plz help


sounds like a problem with the fuel getting overheated and evaperating when turned engine off , check the engine cooling system is pumping through the fuel intake manifold section as a starting point, check that the engine cooling fan runs on after turning engine off as this cools the engine down to stop the fuel evaperating in the fuel lines etc

1987 Cadilac Sedan Deville- where is the fuel pump and how difficult is it to replace


It is located inside the gas tank. The tank must be emptied and dropped out to replace it which is not very easy to do if the gas lines, retaining brackets and bolts are very rusty

Hey i have a cadillac sedan deville 1992 where is the fuel pump located


The fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.
