I need to remove the fuel tank/dash from my A bone and was looking for advice on doing it safely, the tank has been 5 years without fuel. I am looking to cut the tank portion out and use only the cowl top portion as I've purchased a 32 style dash and a beautiful old instrument panel and would like the space under the dash for wiring and such.
Take if off the car. I used a reciprocating saw with fine tooth count. If you're real careful you can get around the baffles inside. I cut mine at slow speed, but there wasn't any sort of fuel in there. Fill it with water first if you're worried.
I fill the tank with water and then when it is out I invert it a let it set in the sun coming through a window and then blow it out with a Hair Dryer. Expect some setiment in the bottom. You can wash it out using rubbing alchohol or another agent of your chosing. Normbc9
remove tank from car, flush with water, then run a hose from a clean running modern car's exhaust into the tank, run till out side of tank is warm. it will then be safe to cut...unless there is a sludge build up in the bottom of the tank. i do this procedure on all the tanks i weld/fix/cut but in one case there was a lot of build up that had trapped fumes under it. i made the first hole then as i started to make the second the sparks hit the trapped fumes. 8 foot fireball out the first hole.
Here are pictures showing how I turned my '28 Tudor gas tank into an instrument panel: http://www.jalopyjournal.com/forum/showthread.php?t=222387
Are you sure your tank don't bolt in??? Some "A's" do. In the photo it looks like bolts along the firewall at that first seam. That is where mine bolted in and also along the kick panels inside the car.
Just did this on Sunday. Mine has been empty for about 3 months with the cap off but still smelled strong enough for me to worry about how to do it. First I rinsed with water, a full tank + sloshing it around. Did this twice. Next I used a carbide hole saw and put a bunch of holes in the part I was cutting out. My logic was that if there was a 'poof', I wanted to minimize pressure build up. You might say drilling holes could spark, and yeah, you're probably right. I was suited up pretty well with ear/eye/hand protection. Strapped it to a table and (still suited up) put a propane torch in each hole I drilled. Was totally fine. Then proceeded to finish it with combination cut-off wheel and plasma cutter. BTW, it killed me a little to cut up a nice-ish tank.
From a welders point of view....Purge tank with nitrogen or argon.I have welded tanks up this way. I watched a underground fuel tank from an abandoned gas station get cut in two with a chop saw once for transport....The guy doin the cutting had a gauge to monitor fumes (lel) which he forces out for 2 hrs with a large fan.There were 6 inches of gas/old stale water in tank. The purge is the safest.... removes all oxygen!
You can buy the panel from Brooksville Roadsters pretty darn cheap. They do not make new Model"A" gas tanks. You can sell the tank real easy and probably buy the panel and be money ahead. The new panel will not require filling the nozzle for fueling the Model "A".
I've been told brookville will trade you a new panel for your old tank. If its in good working condition. I don't know that for fact. Give them a call Posted from the TJJ App for iPhone & iPad
I dig out my safest pair of flip flops, remove my saftey glasses so I can see what I'm doing. Sometimes when my pomade runs dry I like to use sterno gel to keep my hair out of my eyes. Seems to keep it all in place while I'm working in tight places or upside down. Oh, next... fire up torch, and cut! Water also works well, or is handy to keep around incase your neighbors have a fire cause their dumb and careless. I find it tends to rust the sheet metal though. I like old traditional rust verse todays light pale color rust. Good luck.
My tank was cut by me, and Ive done many.. but many here will tell you that your gonna die doing it. use your head, and read up on how its done.
Good tanks should get sold for the $150.00 or so they go for. I bought an original cut off 30-31 top at Hershey many years ago for $10.00, one of my best buys ever. Bob
Too bad you are in Canada or I would cut the bottom of a tank out for you, sand it down and trade tanks. Your good 28-29 tank for one that has already been cut out. I have one with over 20 pin holes in the bottom that is not likely fixable. The one that I have put some time in for my delivery came off of a fordor and had pits around the filler neck where the felt was along with a couple of pinholes in the pits. I soldered the pin holes closed and filled the pits, but would much rather have a better tank. Rod
The fuel tank removal went very well, I am quite content with the results Four steps: Good dish soap and hot water wash Drill and few holes and cut two large "windows" with a jig/reciprocating saw Rough trim with a zip disc Scribe a clean line around the left over edge leaving 1/2" of "lip or rib" and re-cut to line and tidy up with a sanding disc I left the rib to prevent the cowl top turning into an oil can.
It looks great! I'll admit my stupidity and ask, "What the hell is a zip disc"? I'm assuming that it's a metal cutting blade on a grinder? Thanks for posting and saving my eyebrows.
