<div dir="auto">I used a clean and coat system in our tractor gas tank 5-6 years ago because rust was constantly clogging the carb ports.

Moss has a fuel tank cleaning and sealing system for sale. About $125 for all the potions. Consider that versus the cost of s new tank.<br>

>> You will have to take it off and swill it out (or did someone already say that? ...), maybe swirling a handful of nuts around to knock off any lightly sticking bits (and if that's going to accelerate the point at which it leaks then it needs replacement anyway). While it's off check the top of the tank carefully, it often rusts through here first. Be wary about coating, tanks before 1977 have the pickup filter built into the tank and this is more than likely to clog. But if there is that much rust inside the metal is obviously thinning, in addition to any external rusting thinning it even more, so you may be wasting your time and a replacement tank would be better. It depends on your pockets.<br>

>>> My MGB was awakened recently after an unintended 10-year nap. (Thanks Rich!) One of the unfortunate consequences is crud in the gas tank. After I fill the gas tank, the fuel filter gets clogged with rust-colored sludge and we're limping down the road with the engine coughing and backfiring. Is there a fast/easy/inexpensive way to flush the tank? Any other thoughts or sage advice are welcome. Thanks<br>
