How to Install a Fuel Pump Module on a 98 S 10
The Chevrolet S-10 is a compact pickup truck that General Motors manufactured from 1982 to 2004 in the United States. It had a 6-cylinder 4.3-liter engine with sequential fuel injection, which requires a high-pressure electric fuel pump. The fuel pump in a 1998 Chevrolet S-10 is attached to the fuel tank. This requires you to remove the fuel tank before you can install the fuel pump.

Disconnect the cable from the batterys negative terminal with a socket wrench to prevent starting the engine accidentally. Open the fuel tanks filler cap to relieve the pressure in the fuel tank.
2Siphon the fuel through the filler tube with a hose and drain the fuel into a gasoline container. Raise the rear of the truck with a jack and support it on jack stands. Remove the plastic tank from the fuel tank with a socket wrench. Release the clamp for the fuel tanks filler hose and disconnect the filler hose.
3Disconnect the electrical wiring and fuel lines from the fuel tank. Support the fuel tank with a floor jack and remove the fuel tank straps with a socket wrench. Lower the fuel tank slightly with the floor jack. Detach the electrical connections and fuel lines from the fuel sending unit. Lower the fuel tank completely with the floor jack and move it to your work area.
4Turn the locking ring for the fuel sending unit counterclockwise with tool No. J-24187. Remove the locking ring from the fuel sending unit and lift the fuel sending unit out of the fuel tank. Discard the O-ring for the fuel sender unit. Pull the fuel pump into the mounting tube as you pull it away from the bottom support. Pull the fuel pump out of the rubber connector once it clears the bottom support.
5Install the new fuel pump and O-ring by performing steps one through four in reverse order. Start the engine and check for fuel leaks.
