Replace fuel pump/locate

Unfortunately the fuel pump is inside the fuel tank...I have found the best way to remove the pump is to take the entire bed of the truck off..the reason is the straps that hold the fuel tank up have bolts that hold the strap to the frame my experience..these bolts will snap off , leaving you more work to drill them out an so on..if you do decide to remove the bed there are 8 bolts holding it to the frame...once the bolts are removed ,you want to make sure you unplug the harness for the rear lights and also disconnect the fuel inlet assembly,then you can slide it back just far enough to gain access to the top of the fuel tank..The fuel pump assembly(also called fuel delivery module) will have a large "C" type clip holding it in.Using a screwdriver, you'll need to pop it out from around the diameter of the fuel pump. Then you may need to turn the whole pump a little to remove it...being careful of the float arm that is attached to it. Also, there are tools needed to remove the fuel lines, which should be available for rental from autozone. Be sure to replace the fuel filter as not doing this may void the warranty for the new pump. You will need the special tools for this too.

I need to replace the fuel pump in my 1985 Chevy S10 pickup, need all help. What is the procedures?

EXACT PROCEDURE ! Please Rate Me Fairly for this!! Thank you And Good Luck !!


  1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
  2. Disconnect the negative battery cable.
  3. Raise the car on a hoist.
  4. Remove the fuel tank. See Fuel Tank / Service and Repair.
  5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
  6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
  1. Push the fuel pump assembly into the attaching hose.
  2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
  3. Install cam lock over the assembly and lock by turning clockwise.
  4. Reinstall fuel tank.


NOTE: To ease pump installation, rotate the camshaft so the camshaft eccentric is out of the way of the fuel pump rocker arm.

  1. Disconnect fuel lines from fuel pump.
  2. Remove fuel pump mounting bolts and the fuel pump.
  3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
  4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
  5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
  6. Connect fuel lines. Then operate engine and check for leaks.
