610 rust in gas tank

[tdsracing]

Well got a look in the tank today and rust is not as bad as I feared but there are spots everywhere. Owner I got it from says it will plug a filter and or the carb in less than an hour. Gunna run a gravity tank until I find a solution. Thought about acid the tank but can't really put sealer in it as you can't just pick it up and slosh it around. Once I get starter fixed I will be onto this. Is it a common issue and what have been the fixes?

The only way that i'm aware of that seems to last is the one where you put epoxy in and roll it around, but as it's not an option for you, i really don't know.
I have a generator with a tank like that, it just keeps clogging the filter up.

You could try seeing how much of the rust you can flush out of the fuel tank drain port. The port is the furthest rear plug behind the left rear tire. For something like this I flush with fresh fuel and then strain what comes out with a paint filter before putting it back in.

Is that tank common to both sides of the machine like the hydraulic system is? I cant remember. Before you abandon it try taking the drain plug out and flushing it with your pressure washer, maybe make a 90 degree tip so you can get most places in there. Then run the exhaust from the shop vacuum in for a while to dry it.

After you refill it any water left clinging in there will settle to the bottom and can be drained off.

Yes it is common. I have seen several of these machines with "auxillary" fuel tanks. Hope yoi guys come up with a better solution.

Then the common passageway is probably where a lot of the rust may be. Maybe then just flushing with diesel and a small pump and hose would get it the best, I have used the pressure washer with decent results but just on a single tank. The auxiliary tanks I have seen are almost all above the engine so any leak or spillage will not turn out well when the engine is hot.

I agree 100% Jerry...the ones I've seen scare me to death. There are fuel drain plugs on both sides... I would do my best to clean and drain several times. Good luck.

Gunna give it a flush. I like the paint strain idea.
