Rough idle and bucks while driving

1 Open the hood. Locate the fuel pump, mounted to the driver's side of the engine block, approximately midway between the front and rear of the motor.2 Loosen the fuel-line retention nuts on the pump with a tubing wrench turned in a counterclockwise direction. Carefully pull the fuel-inlet line and the outlet line from the fuel pump, being careful not to bend the metal lines. Have a rag handy for any fuel spills when removing the lines.3 Loosen and remove the two fuel-pump retaining bolts with a socket and ratchet. Place the bolts aside for installation of the replacement fuel pump.
4 Pull the pump straight out of the engine block and remove it from the engine bay. Scrape any gasket reside from the mounting surface of the engine block with a gasket scraper.
5 Place a new gasket over the mounting surface of the replacement fuel pump and hold it to the mounting surface on the engine block, lining up the mounting holes. Thread the original retaining bolts through the pump and into the engine block and tighten them.
6 Reconnect the fuel lines to the pump and tighten the fittings with a tubing wrench. Close the hood.
