If the stuff in your tank is gummy and smells bad its probably shellac which is gasoline residue. Denatured alchohol will clean it nicely, use plenty and rinse a couple of times. If you still have rust and crud after the gum is out tumble the tank with sharp pebbles inside it.

I ran across this idea many years ago (I am old) and it has worked over and over for me. I was trying to find something to clean out the old varnish in a clear glass kerosene lamp and although turpintine works, nothing works like Lacquer thinner. Swirl it around and it comes out looking like strong tea and the glass was clean. I next tried it on a 48 dodge, only this time i used a gallon. rocked the truck and drained it. looked like old coffee. The nice thing about it is that any left in there will mix with fresh gas and burn fine. I can't tell you how many times i have cleaned out old gas tanks with it. and it will even clean the lines to the carb. Most any hardware will have it Gary

I flush gas tanks out with turpentine, it removes the rust etc and doesn't hurt if you don't get it all out of the tank.

Phil Heisey, the Cockshutt guru, had this handy tip in an issue of "The Cockshutt Quarterly"- make a little "standpipe" that fits in the top of the sediment bulb fixture- usually a 1" length of the appropriate size copper tubing is the easiest- then you will be getting the gas from an inch above the bottom of the tank, so the crud and scale can accumulate harmlessly. Once in awhile, run the tractor out of gas and unscrew the sediment bulb fixture, rinse the crud out the bottom, and reinstall.

If you would use the search function on this page you can find all of these ideas and more that have been answered before. Also, use plain old vinegar, let set 4-5 days, will "cut" the old gas. I like the boiling idea too. Good Luck with it.

I am cleaning my gass tank right now, it is for a Allis Chalmers C 1948, no gas cap and don't know how long it has sat with out one. Filled it with water and lye, ratio of 1 table spoon per gal. water, took a stainless steel rod slipped a piece of rubber hose up to where it come will come out of the tank and a piece of hose on the bottem to keep it from shorting out there, Hooked up the battery charger + to the rod and neg - to the tank. Just letting the electrolisis remove the rust from inside the tank. Checked it after 2 hours, lots of rust on my rod and more floating inside tank. Will remove electrolite tomorrow and check inside of tank. I already cleaned my oil bath air filter using electrolisis, looks like new metel and no oil or grud in the wire mesh.. also valve cover... the rust that is left on, just wipes off to expose bar metel.
will let you know how tank is after tomorrow.

Hey Keith, that's a great idea. Couple of questions tho... does the rod have to be stainless steel and how many amps and what voltage do you run the charger at. My mom has a farmall a with the same problem.

Does not matter if you use stainless or just a steel rod. I use stainless cause that is what I have and it is easier to clean off the rust. I use an old charger that was used for electric wheel chair, 24 volts. Also have an older charger 8 to 10 amps, 12 volt that I use, have it loaned out to a friend. As far as the amps goes, it will pull what it needs You will notice as the part or tank gets cleaner, amperage draw will gradually go up. I have my tank cleaned and ready to paint. I placed my tank in a plastic container to clean the outside using the same process. removed all the paint and RUST (TURNS RUST TO BLACK OXIDE.which won't react to the oxygen anymore.)Need to do this outside,and away from any sparks cause the process produces hydrogen gas. Good Luck Keith

Mark,

I too, am trying to cleanup my fuel tank on a Ford 801 I am working on. What a stinking mess the last guy left in there for me!

Today I flushed the tank with high pressure water to remove most of the floaties, then I put in a couple of gallons of Napa Carpurator Cleaner and inverted it several times. I will invert it often over the next week. I am also thinking of putting in a couple of handfuls of drywall screws and placing it on the back of our UPS truck for a week of stop and go's, ups and downs etc. (just kidding on the UPS thing).

I will let you know how the Carb cleaner does. The idea of having the radiator shop boiling it out never accured to me, but sounds like a good idea.

Dean

I had the same problems with some old cars and trucks. I took them to a radiator cleaning shop. They can clean them and seal them. Fixed the problems for me on 4 vehicles.
