Experiencing problems installing a new fuel tank into a 39 ford. Tank is to large to manuver into the frame. The tank manf. says cut it or bend it to shoehorn it into place. I hesitate to do that. Any experience with this?

Had the same problem. I had to "ding" the left side to get enough clearance to get the other side past the frame. If it's real close you may be able to use a pry bar to get it past the frame. I have found that this problem occurs with the metal tanks, but not with the poly tanks. The poly tanks go right in easily.

Thanks. I think I am going to have to dent the left side and cut the right side flange off to get this one in. I just hate to start in butchering such an expensive part.

I had the same problem, too bad they can't be made correctly. You will need to ding the left side in about 1/4 inch just below the flange. Grind about 1/8 inch off the right side flange, then pry the frameout slightly on the right as you push the tank to the left. Be sure to check the fuel sending unit opening as it is too small for the original gage. A die grinder will solve that problem. Do it with the tank upside down, then vacuum and rinse to remove any filings. It took me 20 minutes to remove the 70 year old tank, and 3 hours to install the new one, @*#!!

Thanks again. Trjford8 said the poly tanks fit right in, can you tell me whose poly tank you have had experience with?. I have been looking at Poly tanks this morning and the best looking one I have seen is from Tanks Inc., manufactured in Iowa. A poly tank should have enough flex to fit even if it is a little large.

I have a poly tank made here in Iowa, and it installed without a hitch, except for the struggle with those dratted caged nuts that Ford seemed to like so much. My tank has a "donut" molded in the middle to serve as a baffle. The only tight spot was getting clearance for one of the rear tube shock mounts in my '47. Luckily, the mount clamped to the cross member, and could be moved just enough. The metal tank had a dent in it for that purpose. It didn't look like it had been hammered, but stamped with the tank. Unless you are a purist, I don't know why a poly tank isn't a better choice. With today's oxygenated fuels, rust is an increasing problem unless you lay out big bucks for a stainless tank.

Hey Pauls39, The tanks CAN be made correctly IF the manufacturer demands that. I am guessing it to be a "back order bob" tank. They fit like poop even though they are advertised to be an exact replacement.

what was the problem with the original? there is a guy that made a tumbler for gas tanks here in MAINE, he fills the tank with 5/16 steel nuts and tumbles the tank and flushes it out with water till it looks clean,, takes a magnet and picks out the nuts then reseals it . I did this to my 37 tank in 1976 and to this day, have had no problems. I took mine to a raditator shop, they soaked it overnight in their cleaner,which removed most the gunk, when I bought my car it had some gas in it,the gas? was in there for years, looks like replacement is the LAST RESORT,I think they made these when you do a body off the chassis restoration,everybody complains about the new tanks, my 3 cents, 37RAGTOPMAN if it is not completely shot, I would try a reseal first, its worth the money

I agree with 37ragtop. The original tank will accept the original sender and save you from the problems that the aftermarket sending units cause. The baffling in the original tanks is also much better than the reproduction tanks. The new coating from Bill Hirsh is alcohol resistant and will protect the steel from further rust.

I have bought the poly tanks from Yogi's in Iowa, but they are made by "Tank". They go rightn in without any prying. The only 'stickler" is they will not use the stock sending unit.Yogi's does sell a sending unit that will fit the tank and work with the stock gauge. After putting the new steel tank in my 37 and having to "ding' it to make it fit, I will return to using a poly tank in my next project.
