I believe u are referring to the lock ring on the fuel tank that holds the assembly in place, I use a hammer and a sturdy piece of wood (oak flooring 3/4" thick x 2" wide x 6" long), or a brass drift (punch). Place wood or brass against the tabs on the lock ring, tap w/ hammer to loosen (counter clockwise). The reason to NOT use a screwdriver or steel chisel, etc. is because u can make a spark when hitting it w/ hammer, and then u won't need to worry about the fuel pump anymore. Work on it in a well ventilated area!! No heaters going, or smoking, etc.

Replace a fuel pump on a 1996 cevrolet S-10 4 cylinder

the fuel pump is located inside the fuel tank.

  • Park your Chevy S10 in a safe place with a level surface. Make sure you have enough room to work around the truck.
  • 2 Unplug the fuel pump relay, which is located in the fuse/relay box in the engine compartment on 1995 to 1997 2.2L engine models. Markings on the relay or the back of the fuse box lid should identify the relay. On other models, press the small stem inside the Schrader valve--similar to a bicycle-tire valve--located on the fuel inline rail, right before the first fuel injector. Cover the valve with a shop rag as you depress the stem with a small screwdriver to catch the squirt of fuel.
  • 3 Disconnect the black, negative battery cable and raise the rear of the truck with a floor jack. Safely support it on two jack stands.
  • 4 Drain the fuel tank into an approved container through the filler pipe. Use a hand siphon pump if necessary.
  • 5 Disconnect the clamp from the filler hose at the tank with a screwdriver and remove the hose. Remove the tank shield. Support the fuel tank with a floor jack and a piece of wood on the jack pad to avoid damage to the tank.
  • 6 Remove the tank-holding straps with a ratchet and socket.
  • 7 Lower the fuel tank so you can disconnect the fuel lines from the fuel pump/sending unit assembly on top of the tank. Unplug the pump electrical connector and lower the tank to the floor.
  • 8 Turn the lock-ring tabs holding the pump/sending unit assembly to the tank counterclockwise with a drift punch and a soft hammer until the ring is released.
  • 9 Lift the pump/sending unit assembly off the tank, remove the pump and install the new pump in the pump/sending unit assembly. Discard the pump/sending unit O-ring seal.
  • 10 Install a new pump/sending unit O-ring and set the pump assembly in the tank.
  • 11 Lock the assembly lock ring by turning the ring clockwise until it locks in place.
  • 12 Connect the fuel lines to the to the fuel/sending unit assembly and plug the pump electrical connector.
  • 13 Raise the tank to its mounting position and install the tank-holding straps. Install the tank shield and connect the filler neck to the tank.
  • 14 Lower the truck, plug the fuel-pump relay and connect the black, negative battery cable.
  • 15 Refill the fuel tank, start the engine and check for leaks.

    2000 CHEVY TAHOE THE FUEL PUMP bit the bullet so

    Take your vin number to any Chevy Dealer's Parts Counter. They can pull up the parts diagram and give you a part number. The ring is most likely a dealer part. So you will need to go to the dealer anyway to buy this part.

Set the lock ring over the flange, and tap in clockwise with a NON_SPARKING drift. The ring will cam lock into place.

    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.
