how do you remove 1985 thunderbird gas tank

I had a 1985 T-Bird way back when. It has a steel tank and is strapped in place. Once you get the tank empty and unhook the power cables and fuel lines you loosen the metal straps and it all drops down.

Bad news maybe..

Those hard plastic fuel lines are a bitch to get apart and put together in cool weather.

If you live in an area with winter road salt the salt and dirt gets up between the top of the tank and the bottom of the trunk floor, causing the top of the tank to rust out with pin hole leaks.

The lock ring that holds the pump to the top of the gas tank is usually badly rusted, preventing a new fuel pump from having a good tight seal and prevents a good ground power circuit for the pump.

Another typical point of failure for the fuel pump circuit is a power relay tucked in next to the computer under the passenger kick panel. When it goes bad your battery goes dead and after you recharge the battery you notice every couple of seconds the fuel pump cycles, even without the key in the ignition.

This was with the 3.8 V6 and C5 automatic.
