Replace Fuel Pump 1997 Quest See full article with pictures here: http://www.fixya.com/cars/t1768960-fuel_pump_removal (1) If the fuel tank has more than one third full, you need to get the gasoline out. If it has one third or less full, you can leave it in the tank. However be very careful around the working area. Make sure you have read fire precautions in a general repair book. Jack up the rear of the van. (2) Remove the fuel tank protector. (3) Disconnect fuel pipes at the front end of the fuel tank. Use short pencils and extra rubber hoses to block disconnected pipes and hoses. There are two pipes connected to the gasoline filler at the side of the van. Disconnect only the smaller one. The larger one is flex enough for the tank to be lowered. (4) Disconnect the electrical from this connector. Jack the rear end of the fuel tank with a car jack and a piece of 2x4. Put the wood between the jack point and the tank. Then unbolt the two bolts showing in the picture. (5) Lower the jack after the bolts are removed. The rear end of the tank should be lowered. (6) Disconnect fuel lines on top of the fuel pump. Reconnect each short hose back to different pipes as shown in picture to block the pipes. (7) Loose the six mounting bolts on the fuel pump assembly. The bolts should be loosen a little at a time in multiple turns. Also detach the electrical wire holders. After all bolts are removed, carefully take the assembly out of the tank. (8) Remove the fuel pump from the assembly as shown in picture. Then unplug the electrical wires. Note that two connectors are in different sizes, so that you will not be able to reconnect to a wrong terminal. (9) Put the new pump and new filter in. Reconnect the electrical wires. If necessary use a pair of pliers to make the connectors tighter. Make sure they are not loose. Reconnect gas inlet to the pressure regulator. (10) Use a new O ring, put back the assembly to the fuel tank. Make sure the float of the fuel level senser is free, and the assembly is at the right orientation (as shown in picture). Screw back the 6 bolts after making sure the O ring is in right place. The bolts should be tightened in turns. Do not over tighten them. Then reconnect the fuel lines and make sure every fastener is tight. Put the electrical wire into holders. (11) Jack up the tank and put the two mounting bolt in. (see picture in step 4). Make sure they are tightened with specific torque. Reconnect the electrical connector. (12) Reconnect two fuel lines at the front side of the tank. Refer to the picture in step 2. Reconnect the hose to the gasoline filler. Before you have a try start, double check if all fuel lines are securely connected and tightened. (13) Start the engine. You need to crank more than a normal start because the lines were empty. The pressure is built up in some time. (14) If engine starts ok, turn it off. Then check under the van if there is any leakage. If everything is fine put back the tank protector. (picture in step 2).

How to replace a fuel pump on a 1993 Nissan altima?" Remove the back seat. The fuel pump is located under the seat. Will either unbolt or have a locking ring, remove whichever the case may be. Lift fuel pump out of tank, install new one with new gasket.
