ELECTRIC PUMP

REMOVAL

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.

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.

SOURCE: where is the oil sending unit located on a Chevy S10 Pickup.

MY S-10 IS LEAKING OIL. I WANT TO KNOW WHERE THE OIL SENDING UNIT IS.

SOURCE: 89 Chevy S10 pickup. symptoms of needing oil pump

Replace the oil sending unit, this will take care of the jumping gauge. On the fuel, I would start with replacing the fuel filter, see if this helps. But my first guess on it would be the catalytic converter is clogged up.
