H: Rusty Fuel Tank

Sapper55 · Jul 7, 2014

Gentlemen,
I have a '42 H that I use as a working tractor. I was bush hogging today and it stated to run rough and finally quit. I knew it was a fuel related problem, so I removed the fuel bowl assembly and cleaned out a lot of rust and scale, reinstalled the assembly and went right back to work. The same thing happened again about 15 minutes later. I removed the tank and cleaned it out a few months back and had no problems. Is there something to clean the rust away or what? I appreciate any ideas.
Regards, Sapper

Sap..Pull the tank off and drop in a bunch of washers and hex nuts/bolts. rolled it around or strap to a nother tractor rear tire and drive around a bit. I usually remove the hardware then fill with a water/muriatic acid mix and let set for 30 minutes or so. Drain and rinse thoroughly. Add a box of baking soda when rinsing to neutralize the acid. Use a hair dryer to dry inside of tank. Also use a 3-4" piece of straight copper hose inserted in your fuel sediment bowl inlet. You will not have any more issues....

Muriatic acid is all you need. Please do NOT use the nuts, bolts, rocks, sand and other assorted hardware and junk. That stuff will become lodged and trapped behind and under the baffle, and you will never get it out. Also, there is absolutely NO need for that fuel tank liner stuff. It will only cause you MORE grief in the future. Been there, done that, got the T shirt.

everybody has differene experiences, I know, but I used Red Kote liner and it worked well. You got only one chance, put it in, roll it all around, upside down and sideways, get everything covered, and drain it out, and you're DONE. Don't try to re-do it.
Before that, I screwed in a piece of screen mesh into the sediment bowl pipe, and inserted the gizmo back into the tank, it kept rust out.
