When I bought this car, it was not running, and when the ignition key was turned on, the fuel tank did not make a sound.

After checking the fuses and fuel pump relay, I determined the fuel pump was bad.

I could smell gas, so I knew there was at least one or more leaks and a fuel pump issue, so I undertook the gas tank removal.

This involved taking off the cat-back exhaust, the trailing arms, the panhard bar, the drop links, the lower shock bolts, and the filler cap and trim.

The inside of the gas tank was rusty because the car had not been on the road since 1994, so I sent the tank out to be dipped and repaired and a plastic liner installed.

The red liner looks much better than the rust that was there.

My gas gauge wasn't working, so I installed a complete assembly into the newly painted tank.

I then reinstalled the tank.

Since I had the heat shield and exhausted, I finished them with high-temperature paint.

When I reassembled and tested it, I replaced the fuel filter, flushed the fuel lines, and had the car undercoated.
