using phosphate in a MC tank.

[Guest]

would there be any problem with phosphating the inside of a motorcycle tank? it has some rust inside, i was thinking of using straight phophoric acid to eat the rust away and then rinsing and drying. any cautions or ideas? it is for a 69 kawasaki dirt bike.

Re: using phosphate in a MC tank.

I'm going to tell you the cheapest, easiest, most non-toxic method. But you have to promise not to laugh. Cola. Go to the local Mega-Mart and buy as many 3 liter bottles of cheap cola as it will take to fill the tank. Filler her up, and let it sit. I usually go a full day or 2. Rinse well and you'll be shocked at the results. I know, you're thinking it's BS. I'm dead serious. I've worked as a motorcycle mechanic. I've use every tank treatment you can think of. Some of them work faster, but none of them work better than cola. And it's safe to have around. If the tank is really bad, you may have to do it twice. But it will work. Just make sure you rinse it out well.

I didn't believe it either until I tried it.

BTW, the active ingerdient doing the work is Phosphoric acid which is an ingredient in soda. It's just more diluted than straight acid. Less fumes and safer to have around.

Welcome to the forum tr4dude. Let us know how your tank comes out and if you do the cola trick.

Re: using phosphate in a MC tank.

I would use some nuts and bolt first to knock out the rough stuff and then give the soda a try, then iron phosphate (hot) after rinsing the soda out real well. I would slosh the phosphate around for at least 5 min or so to make sure it reaches everywhere in the tank.

I can't imagine the phosphate causing any problems, and would think it would be good protection against future rust inside the tank.

I store all my metal cycle tanks full over the winter, and add the correct amount of Stabil and 1 or 2oz of 2-stroke oil to the gas for extra protection as well - beats trying to get rust out of the tank and fuel system later.

What ended up happening? Did the cola work for you? I hope so, I'd hate to be spreading bad info. But it's always worked for me.
