SOURCE: replacing fuel pump on 2002 sunfire

after the straps are off ,it should drop a few inches about eight or so ,than you should disconnect the two lines beside the fuel filter that run to the fuel pump,than you should disconnect the third one at the fuel pump,than once complete slowly pull the tank to the passenger side of vehicle,it will take a little foce but will come,it really helps if you could get the vehicle up about a foot or more before starting and you should have more than enough room to pull tank and fuel pump out,undo the two plugs than you have to turn the locking plate counter clockwise thats on top of fuel pump to get the pump out and if taking the tank right out disconnect the main line for fuelling

SOURCE: REPLACING FUEL TANK STRAPS

I know it can be a bear if the bolts and pins are rusted. Unless the new straps are OEM, some after market straps don't fit quite as well and you need Godzilla strength to manover them into place to get them pinned and bolted back up.
You shouldn't have to drop the tank as long as you do the straps one at a time. Get a floor jack, transmission jack or even a motorcycle jack and place wood under the gas tank and do one strap at a time. I used a second jack to help push the strap in place so I could push it into place on a 97 Dakota. Good luck and sometimes it goes smooth but, some times it makes a preacher say things they wouldn't say in church. :)

How to drop gas tank on 2005 CTS Cadillac


Much easier if the tank is empty. Siphon or pump the fuel out of the tank. Disconnect the negative battery cable. Raise the vehicle and install jack stands to ensure the vehicle is not going to drop on you. There are mechanical straps that hold the tank in place. There are also electrical connections for the fuel pump and fuel lines to be disconnected. Place a jack under the tank to support it and then remove the straps holding the tank in place. Lower the tank enough to gain access to the fuel lines and electrical connection. Disconnect the electrical and fuel lines and lower the tank until it clears the vehicle.
Be VERY careful with the fuel that was drained and whatever fuel remains in the tank. It is very dangerous.

What is involved in dropping the gas tank so I can replace or clean the fuel sending unit?


not too bad as long as you lines and straps are in good shape. dis connect battery first. you will need to remove fuel filler tube, electric connector fuel lines and vent line , un- do tank straps. you need to get the car up high enough to drop tanks and helps if you have someone to muscle the tank up and down with you. hope you do not have much gas in tank. also do not try to clean sending unit. just replace it. you do not want to do it twice. take care not to break any wires of fuel lines.

Where is the access panel for the fuel pump


There is no access panel for the fuel pump- You have to drop the tank to get at it!

1. Syphon any gas from the tank

2. Prop the gas tank with a support

3. Loosen the tank straps and fill hose strap then disconnect the straps on one side

3. Drop the tank

4. Disconnect the fuel lines and wiring harness

5. Pull the tank from under the vehicle, turn the pump seal counter clockwise then remove the pump- Careful not to damage the O-ring gasket as you may need to use it again because the new gasket may not fit properly

Install in reverse order

Normally it's just a matter of removing filler tubes from side, disconnect fuel lines & electrical connections at fuel pump/sender, undo the 2 straps, & lower it down.
