Nissan Sentra Fuel Pump Replacement Q. Hi, I have a 1992 Nissan Sentra, and I need a diagram or some steps to changing the fuel pump. I have been stuck on changing this for a few days. It's an automatic transmission, about 112,000 miles, and it runs awesome other than this little problem. Thanks, Kory

A. Piece of cake! You don't even need to drop the fuel tank. Here's how.

Fuel Pump Fuse Location

Release fuel pressure: Remove fuse for fuel pump. Start engine. After engine stops, crank engine two or three times to make sure that fuel pressure is released. Turn ignition switch off and install fuse for fuel pump.

2. Remove rear seat bottom and back cushion.

Fuel Pump Access Cover

3. Remove Inspection hole cover.

CAUTION: Use rubber gloves to prevent fuel from contacting the skin when removing the fuel hoses and pump.

4. Disconnect electrical connector and fuel hoses.
5. Remove the six screws.

Gauge/Pump Assembly Removal

TECH TIP: The sheet metal for the top of the fuel tank is REALLY SHARP! One way to protect yourself is to take some door edge moulding and apply it to the lip of the tank opening. Vacuum hose sliced lengthwise will work too.

6. Remove fuel gauge sending unit and disconnect the fuel hoses and connector.

Fuel Pump Removal

7. Remove fuel pump from fuel pump bracket by pinching the tab and lifting the pump out of fuel tank bracket.
8. Installation procedure is the reverse order of removal noting the following:
   • Always replace fuel tank O-ring with a new one.
   • Verify the two hoses to the plastic cover plate are installed correctly. The engine won't run if the hoses are reversed.
   • Tighten screws to specified torque 2.4-3.1 ft.lbs.
   • After installation, run engine and check for leaks at connections. Also verify the fuel gauge works.
