1947PLEVY Posted January 30, 2008 Report Posted January 30, 2008 Hello All: I was wondering what would be the best thing to use to coat the inside of a gas tank. Thank you all and God Bless us All.. John 47Plevy Quote
Rodney Bullock Posted January 30, 2008 Report Posted January 30, 2008 what is wrong with your tank? is it just old and rusty or does it have holes in it? Quote
48mirage Posted January 30, 2008 Report Posted January 30, 2008 See if you can find a radiator shop that can boil out the tank and then apply "redkote". A lot of us use it in our motorcycles. It stands up pretty good to today's gasoline chemicals, including alcohol. (Some alcohols will change it's color). MEK is the solvent used to thin and remove it. Quote
1947PLEVY Posted January 30, 2008 Author Report Posted January 30, 2008 The tank is old and had alot of rust in it. Not sure if it has any holes in it or not, hopefully not. Take Care and God Bless us All... john 47 plevy Quote
Young Ed Posted January 30, 2008 Report Posted January 30, 2008 I heard on I think oldihc that the guys not in a hurry will stick the tank in the back of their daily driver truck with a length of chain inside it. The driving makes the chain rattle and slide and knocks the rust off. Rotate the tank so the chain works on each side. Sort of a slower method of the cement mixer idea. Quote
RHDSP15C Posted January 30, 2008 Report Posted January 30, 2008 Kanter has the stuff to do this. The whole kit lists for $60 and the sealer is $20 for a quart. Quote
Rodney Bullock Posted January 30, 2008 Report Posted January 30, 2008 The reason I asked the question is if the tank is just rusty any radiator shop can dip and boil it. If it has holes then it will need repair, cleaning a tank at home is one thing, repairing an old tank is another. I have repaired tanks before and had the lining come loose, stopping up the feed hole. If the sides can not be primed then this could happen. There is a company called re-nuz-it around here and they are excellent at fixing these old gas tanks. Quote
wilmot andy Posted January 31, 2008 Report Posted January 31, 2008 dodgepu1946, just wondering why you were on the oldihc? Just wondering as I go on there too, I have a 1946 K2. I had my tank acid dipped at a shop, found a few pinholes but the tank was still solid. I used redcote in it. Quote

knuckleharley Posted February 1, 2008 Report Posted February 1, 2008 The tank is old and had alot of rust in it. Not sure if it has any holes in it or not, hopefully not. Take Care and God Bless us All... john 47 plevy I have yet to see anything that stand up to "new gas". I had the red plastic coating put into a tractor gas tank a couple of years ago,and the gas started dissolving it within a year. I drained the old gas out to start it,and it came out red. Since this gas tank was so thin it had a bunch of pinholes in it ad it sits right over the engine,it couldn't be trusted after that. Had a Harley gas tank coated with some kind of white tank sealer crap,and it kept clogging the gas line. I won't screw around with them anymore because there is too much danger of fire. I will either buy a new gas tank ($229 from Tanks,Inc) or have the outside coated with fiberglass and then eat out the rust with vinegar before using it. Quote
Fireball Posted February 1, 2008 Report Posted February 1, 2008 I have used this tank sealer kit in several museum age vehicles, not a single problem during the years when done by the instructions. http://www.por15.com/prodinfo.asp?grp=FTRK&dept=11 Quote
48Dodger Posted February 1, 2008 Report Posted February 1, 2008 I heard on I think oldihc that the guys not in a hurry will stick the tank in the back of their daily driver truck with a length of chain inside it. The driving makes the chain rattle and slide and knocks the rust off. Rotate the tank so the chain works on each side. Sort of a slower method of the cement mixer idea. Actually that's a recommendation of a few makers of gasoline tank sealers like Red-Kote. They don't recommend "boiling out" tanks because of the break down of the tin/lead plate (the stuff that was suspose to keep it from rusting in the first place!) And I don't know if Ethanol isn't eating up stuff like Red-Kote over short periods of time. Most companies claim Ethanol treated gasoline doesn't affect 'em. We have 6-10% in California, not sure what everyone else has. I just bet with all the changes in fuel lately, they might have a hard time keeping up. IMHO 48D Quote
Young Ed Posted February 1, 2008 Report Posted February 1, 2008 Pretty sure 10% is the most anyone has for now. I suspect with the new regs that passed that will be going up. Of course there's also E85 but thats a whole different idea. I might try the chain thing for my next project just because its got a budget of 0. Quote
Rodney Bullock Posted February 1, 2008 Report Posted February 1, 2008 I just read a post that stated if you boil out a tank that removes The tin/lead plate. I repainted it with that zinc coating from eastwood that is made for tanks, Will that replace it? This is done on the outside. Quote
48Dodger Posted February 2, 2008 Report Posted February 2, 2008 Pretty sure 10% is the most anyone has for now. I suspect with the new regs that passed that will be going up. Of course there's also E85 but thats a whole different idea. I might try the chain thing for my next project just because its got a budget of 0. In California E85 is a big tax loop hole for car makers. Flex Fuel cars give'em fuel credits...cheap for the car maker, about 100 bucks extra to make a car a Flex Fuel vehicle. Last I heard 240,000 FF vehicles and only 8 E85 filling stations. Not to mention that E85 gives you 25% less HP. So you better have at least a 25% savings at the pump to break even. I know places like Brazil are running 100% Ethanol. Isn't the mid west on 30%? So if Red-Kote puddles, it never dries, because of the "skin" it forms (that's from thier instructions). At that point gas will break it up into "strings". So How is it all this alcohol isn't affecting the coating? Just a bunch of questions on my mind.....I know my tank project is just around the corner. Quote
Young Ed Posted February 2, 2008 Report Posted February 2, 2008 We are still only at 10% ethanol. And if you want for old cars you can run no ethanol gas. Quote
