1985-86 10037262 (V6 & L4) (more baffles than 1984?)
1987-88 10041442 (V6 & L4) (bigger than 84-86)
I tried installing the 87 GT tank my 85 when doing the 3800
swap. No go- It bottomed out on the sides with still 1 1/2"
to go. Apparently, GM modified more than just the tank to
get the extra fuel capacity.

- If you can still drive the car, but are replacing your fuel pump
because it's starting to flake out or something, drive it until it's
almost out of gas. This will make removal of the fuel tank MUCH easier.
- Remove the Fuel Pump fuse. It's at the top one, second closest to the
- Start the car and let it run until it dies. Do this until it won't
start anymore to relieve the fuel pressure.
- Disconnect Negative battery cable.
- Jack up BOTH ends of the car and place it on jackstands, so that the
car is level. On a GT or aero-nose SE it is easier to jack up the front end
- Remove the catalytic converter heat shield.
- Disconnect the connector for the fuel pump. I found it about halfway
up the firewall, right between the A/C hoses which are wrapped in silver
- Loosen the clamps on all of the hoses at the back of the fuel tank.
- Find an empty soup can or something. DON'T use a plastic/styrofoam
cup, because the fuel will most likely cause it to melt.
- I removed the fuel sending hose first, which had most of the fuel in
it. It sprays a bit at first so it's hard to catch some of the fuel.
Next, I removed the return line which had a little bit of fuel in it,
but not much. The line for the vapor canister, and the two large hoses
for filling didn't have any fuel in them.
- Remove the four 13mm bolts on the main support underneath the fuel tank.
- Place a floor jack under the rear end of the fuel tank.
- Remove the 13mm nut from the rear support strap, then the front.
- My fuel tank stayed in place, but yours may want to fall down, so keep a
hand under the front end of the tank (as long as it's pretty empty).
- Lower the jack, and move the tank out from under the car. You may need
to pull on the tank as you lower the jack to get it to come down.
