I'm trying to get my 7 running after sitting for two years so I'd like to drain the half-tank of fuel in there. Yes, I was too dumb to put stabilizer in.

When I went to look at the drain the thing looks like it's covered in some kind of putty. Maybe it is just 10 years of road crud though. Have a look before I take a wire brush to it. I guess I could just siphon the gas out but would rather go this route.thanks

It is undercoating. You might be able to just pull the fuel pump and suck the fuel out that way as it may be a good idea to change the fule pump due to it sitting.

I drained my tank the other day. It's just undercoating. Had to use a small breaker bar to get it loose. Pretty easy to drain the tank. Just make sure you have a large container for the gas and leave the garage bay door open for ventilation or do it outside. I turned the breaker off in the garage while draining the tank just to be safe.

undercoating? no way!

That is either road crud build up or something of that nature. I bought a new tank a few years ago and the drain bolt was totally "un-crudded" - if that can be considered a word...

Thanks all for the reassurance. I was worried I'd have a leak if i started removing that. I had to cut it off with a blade and then cleaned it up with a metal brush. Surprisingly it busted loose no problem. Had an accident two years ago and a kid shortly after, 7 was left neglected with half a tank in there.

How do you think a lawnmower would like 2 year old 93 octane?

perfect use for it.

welcome back and good luck with both the kid and the car.

all the cars were undercoated from the factory, at least that is what i have noticed. so yeah, they always have that crap on the tank. sometimes my sarcasm does a flyover.

It'll probably run it but it will hate to start. Which is why you should always drain your lawn mower each fall and snowblower each spring.

Personally I just mix it in with a daily driven vehicle with no more than half of the old stuff at a time.

Thanks for the welcome back gracer7! The 7 community has always been awesome.

And degeesaman, thanks again for your couple comments way back when I was working my crazy project on this car: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/dual-radiators-when-amateurs-take-big-projects-626562/
