There is some stuff that you put in tanks and it coats it and seals holes and really does work.Can't rememeber the name though ,it was made for repairing motorcycle tanks.Steve

Is the Kreem Tank Liner the stuff you're thinking of?

Neil,

I use the Kreem product. If it's not clean, I don't think the liner will do much good, long term. This is what I do.

For the cleaning part, take a small chain, I have about a 3 ft. peice of some 1/8 link stuff. Put it in the tank with some lacquer thinner. Roll it around for a while. Don't forcefully shake as you may dent it. Dump it out and rinse with clean lacquer thinner. This seems to do a good job of knocking off the scaley stuff and the lacquer thinner will help with any varnish from old gas. Let it dry so as to not mix the following chemical.

I'm a big fan of the Jasco Prep and Prime or any phosphoric acid product to neutrilize the rust. Put a little in, swish it around and dump. Let dry for a couple of days. Rinse with water and let dry again. A little air from the air hose blown into the tank helps to circulate air and dry the tank but let the prep dry on it's own. It's working as it dries. The metal prep will not let it rust again. I've also used a dash of lacquer thinner to help displace the water and speed drying.

I have fixed minor holes with solder or JB Weld. Both have worked for me. It's important for both to work well that the tank be clean. Outside at the repair spot as well. If soldering, be careful with the flux and rinse the inside again after it's repaired. Rusty metal will not solder well so, epoxy may be the better choice. Usually it's the inside that's rusty and soldering will work. Rinsing will also will tell you if the repair is good.

I then coat it with Kreem tank liner. I have heard the POR product is also good but have not used it myself.

It doesn't make sense for me to keep a full tank of gas my crawlers, for several reasons, which would help prevent the condensation from creating more rust. This seems to work well for cleaning and stoping rust from coming back. I do all mine this way.

Thanks for the info guys I have a couple of bombadiers with the same problem. Seasonal use is a real pain sometimes. All the machines I got are used in the winter on the ice. Refueling when the snow is flying is even trickier than in the rain. moisture is a real pain too. Should have everything running soon tho.
