Curing rusty H gas tank for the winter

Had a few stalls and reduced power situations with the '47 H during the last snow-plowing. Haven't had time to go over all systems since I bought it this spring. Made it to the barn at least but wasn't able to get it started after that. I wasn't getting a gas smell during starting attempts so I pushed a wire through the fuel line and cleaned the carburetor and sediment bowl screens. I only got a good stream when I took a thin rod and nudged some rust flakes from the outlet opening inside the gas tank. This cured my problem for now but I'd like to know it's not going to come back during some blizzard.

It's got some rust around the threads where the outlet pipe screws into the tank - about a 1/4" band around the pipe. I'm worried I might break away part of the tank if I try to unscrew the outlet pipe/shutoff/sediment-bowl assembly. If this happens, is that something that's a fairly easy brazing fix or should I have a line on a new tank before I make the attempt? I just don't want to be down during the next storm.

OR should I just roll some pea-sized gravel in the tank, hope that breaks off enough of the next generation of flakes to get me through the winter and do the sandblast, etch, coating of the tank in the spring?

Thanks,

Dave

I duct taped a piece of garden hose on my wet/dry vac and used a flashlight and sucked it all out.

Brother in law used a vac one time to start a siphon to drain a tank and the spark from the vac motor and gas fumes didn't get along very well. Vac exploded. It wasn't a wetdry vac though. I'd be careful about using a vac cleaner.

Yeah, I've heard of competitions on frozen lakes where someone runs a long extension cord out to two competing vacuum cleaners. Both of them have their intake hoses stuck in a gallon of gas. After it's all set up and everyone has backed far enough away the juice is connected and the first one that blows up wins.

I think this method would work if I let the gas tank dry out and blew out the fumes but I'm going to try the magnet (when the rain lets up a bit). I'll post the results after I give it a try.

Dave: You might think that this is an extreme suggestion, but I guarantee that you will never have another rusty fuel tank problem. 1. Take the fuel tank to a radiator shop and have it boiled out. This will eliminate the rust. 2. Call a company called "The Finished Look" located in Sacramento, CA and order their Fuel Tank Repair
Kit. They have two Fuel Tank Repair Kits: One for a 12 gal. tank for $45.95 and a kit for a 25 gal. tank for $49.95. Phone number for the "Finished Look" is 800-827-6715. Just follow their directions and you will never have another problem with rust for the life of the tractor and more. I have used their products and they are great. It may cost more than all of the home remedies, but as I stated before I will guarantee you that it will work.

Best Regards,

Dale B.

I wonder if you could take a magnet on a flexible handle and retrieve the larger rust flakes? I have never tried this but the thought just came to me. Try it and let us know how it worked...

The magnet method was what I was looking for - thanks. As often happens with these problems, it was worse than I thought. I picked up six or seven 'loads' of medium-sized flakes on a 1/4" x 1" surface of an inspectors magnet. It looks pretty clean of flakes now so I think I'm at my get-through-the-winter goal.

Great idea. Should've thought've that myself as I've got an inspector's magnet just a few feet away. It's the kind of device that can reach down at an angle through the filler opening to the outlet pipe. I'll post another follow up on how it went this evening.

We had the same problem with our H. I think we unscrewed the bowl,if you can, and rigged up another piece of pipe with the same threads to screw up into the tank that had enough threads to stick up into the tank an inch or so then the bowl screwed into the pipe. Simply, the end result was a pickup that didn't suck from the very bottom of the tank. Eventualy I took the tank off, dumped in a few nuts and bolt, shook its' brains out, then rinsed it with diesel fuel, repeat. This cured ours, good luck.

You might try flushing it out with turpentine, worked on a couple tanks I had, but you would need to pull the tank off the tractor. Then put in a gallion of true turpentine, not paint tinner and shake the #$% out of it and the flip in over amd drain that out in to a can and see how it looks in side. Hope this helps some

I would flush out as much as you can from the bottom of the tank through the sediment bowl. i would not try to unscrew it, may break the tank and find it is rusted too thin to braze. I would throw on a cheap inline filter to the carb and keep a few on hand. Easier to repoke a wire into the tank and change a filter than dissasemble a carb for cleaning in a snow storm. The intake screen into the carb is not fine enough to stop particles that will clog a jet. Save the proper fixing for a nice warm sunny day.
