Dirty fuel tank

Newbie to this forum, and to the Porsche 944. This is the best porsche forum Ive seen on the net yet.
Ive built Z's for years, and always built the suspension to compare to the Porsche - so I finally gave in and bought a '85 944(early). 94K orginal miles, very solid, NO rust anywhere, needs paint (clear coat is gone) - BUT --this car sat for 10 years and the fuel tank is full of crud- and a little rust.(Hey, the Price was right -almost free..)
I Bought the POR15 gas tank repair kit(cause a new tank is $2,400 more than I want to spend),and I pulled the exhaust,trans,axles,and tank- but Im a little skiddish now - usually I would start with a meduim strength muriatic acid solition and boil it out- but I dont know what the tank is made of - and if it's not good old steel I could get into trouble real fast - -does anyone out here know? any other question I had has already been answered by reading the other posts.(thank-you very much!!,as I said - excellent forum!) Several people have told me it's not worth it- but I Have driven a 944 before, and know that the handling is the best.I'd like to put it back on the road, quick- Anyone with comments greatly appreciated.

My car sat for 7 years and I have the same problem. All I did though was put an in-line fuel filter in between the pump and tank, that way the pump doesn't get screwed up, and I just clean it out every once in a while. I considered pulling the tank and taking it to a place that can coat the inside, there is a local place here called "Ropple's". But never got around to it. I would think the repair kit would be fine though.

The tank is good old steel. Your repair procedure seems to be thorough enough.

Good luck and welcome to the board.

--thanks- I was worried (not knowing how porsche built these) there might be an aluminum / tin fitting down in there somewhere...I'll let you know how it turns out.

Pearl if you decide to do this, the best way is to take it to a shop, unfortunately theres none near me that can or will do it. (right, anytways) I had one shop tell me they would cut a large hole in it,sandblast it, and patch it with Fiberglass. [UMM no,-thanks..] I found this link, which is pretty much exactly how I do it, http://homepage.mac.com/ratwell/FuelTankRestoration.html - thanks to Richard atwell, for documenting it... It takes time and patience to do it right, Ive followed that same method 3 times on 260/280z's and never had a complaint or problem. Theres a couple more baffles in the porsche, I noticed, though....

I just recently did the clutch job and didn't have time to drop the tank while the tranny was out. I don't think I'll be messing with pulling the tranny out soon again. Thanks though.
