Hi. New to the board.
Recently my girlfriend and I watched our beloved 240 burn away right before our eyes.
Never had a chance to get to the bottom of the issue but I believe we let the gas tank get too low before filling it up and sprung a leak, spilling fuel all over just behind the drivers seat and under the car.
My girlfriend drove it home and left it to air out until I got off work. I get home, stumped, I remove the seats... Begin to pull up the carpet... And somewhere a hot wire (my under seat sub, or maybe one of the lights behind the handbrake) touched gasoline and the whole cabin filled with flames immediately. By the time I had my hands on an extinguisher it had ignited the bucket sitting under the car to collect the drips.
I'll never forget to disconnect the negative battery cable again, that's for sure.

But we found a cheap '81 240 coupe and of course there is some rust. Worst of it is the underside of the body (been in and out of Alaska most of it's life). When I pulled the seats out to vacuum the carpet I decided to pull it back in the rear and the entire floor of the car is rusted very badly.
The fuel lines run through there don't they? And i didn't check but I'm sure the rust could spread to the fuel tank right?

Does anyone have any recommendations or info so that we can avoid having any fuel leaks down the road?
