Im helping a friend with a new to him tank.
There was a ton of rust in the tank so we used Evaporust, about a gallon or so, and let it sit over night. The good news is it got a great deal of rust out of the tank but there is still a little left.
My question is how bad is rust in a tank, even just a small amount? What will happen?
He doesn't really have the money to have it done professionally. The inside of the tank looks to be about as good as the tank he has on his bike and there are no problems.
Thanks guys!
Carbed? Jets will plug
FI? Injectors may clog...depends on whether the rust makes it past the pick-up sock in the tank.
Either way, nothing large enough will make it into the cylinder to do *real* damage per-say. Just make sure everything is out of it...if it were mine, I'd do a ton of fill/drain cycles with some water, a few with gasoline, and call it good.
With steel tanks I like to throw in a bunch of nuts, small bolts, small lengths of light chain and shake the hell out of it. Rinse thoroughly. For heavy rust I add these items and wrap in heavy movers pads or blankets and tape and run through the dryer.

It is carb'd, '82 Yamaha Maxium. Is there still a risk of clogged jets with an in-line fuel filter?
We just finished painting the tank today, gonna let it cure tomorrow, and wanted to install on Tuesday. We planned on installing an in-line fuel filter, as there never was one, and filling the tank with new fuel. I was thinking that running that fuel through the new filter would help catch any more loose rust. On the next fill up we would replace the fuel filter again and go from there, another tank of clean gas and maybe even another new filter.
Would this process work at all?
And as a clarification of the first post, we put 2 quarts of Evaporust in the tank let it sit on every side of the tank for more than 30 minutes per side. We then drained it and thoroughly rinsed with water. The next day we still saw rust in the very bottom of the tank and filled it again with a little more than a gallon of Evaporust and let it sit for more than 24 hours. After draining and rinsing the rust was significantly reduced.

Rust will clog the fuel filter and cause fuel starvation. I suggest POR 15.

I would just get the largest clear plastic fuel filter you can (it will be about 2" in diameter) so you can keep an eye on it and carry a spare.
