Replace fuel pump 2002 GMC Sierra

I have removed screws from filler hose, are the fuel lines flexible enough to remove the tank straps and let the tank down?
Can you provide the proper steps for removal of tank for access to fuel pump?

Thanks

I don't think there is enought slack to drop the tank without unhooking the lines. You can take this advise if you want or not its up to you, but i always found it easier to unbolt the bed and lift it back about a foot and i could get right at the sender where the pump is and in some cases i dident even have to unhook the fuel lines, pull the sending unit out chg. the pump and put it back together. Or you can do it the other way, unhook the lines, electrical wires, filler hose, and straps, if its got gas in it better have some help 8# a gal. adds up.

How do you replace a fuel pump on 1994 jeep grand cherokee


Disconnect the battery, Jack the rear up on stable jack stands. use a smaller jack with a piece of wood to stable the load under the tank. You will see 2 band straps under the tank, remove the bolts, only 1 side have bolts, the other side swings down. The hose from the gas cap will have to be disconnected, which can be !!!!! when in-stalling. you can then drop the gas tank down easily with the jack just a bit, enough to reach around to unplug the fuel pump plug, and the gas lines. Once it's removed, the pump has a big screw on ring, take it off and the fuel pump can be pulled out.

REPLACE FUEL PUMP GMC 2002 SIERRa


the pump is in the gas tank siphon the gas out and remove the straps holding the tank(you will also need to remove the three screws holding the filler neck to the truck box under the filler door.)as you drop the tank you will also need to unplug the wiring to the top of the tank and the fuel lines they are usually plastic clips,but if this has been done before and the clips got broken from the first time they could have put clamps in place of the clips.I have found it much faster to remove the truck box itself and that way you don't have to drain the tank and it stays stationary while you RandR the pump with less chance of breaking anything.
Also did you double check the fuel pump relay under the hood in the relay box,I would start there first.
Hope this helps good luck.

Replace Fuel Pump for 1997 Nissan Quest

(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. Take the fuel pump fuse out from the fuse box near the battery. Run starter for a few seconds. This will remove the fuel pressure in the gas lines. Disconnect battery at negative terminal. Jack up the rear of the van.

(2) Remove the fuel tank protector.
19add47.jpg

(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.
59aa089.jpg 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.
128654f.jpg
(5) Lower the jack after the bolts are removed. The rear end of the tank should be lowered.
667f695.jpg

de57889.jpg

(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.
585888a.jpg
(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.
dceea20.jpg

(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.
1310aad.jpg
(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.
08db176.jpg
(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.
90c2053.jpg
(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).
