My 1973 110 has a recurring problem with the rust from the gas tank getting thru the filter into the bowl and mucking things up. Already did the fish tank gravel shake and bake thing inside the tank, with a neutralizer after rinse, and rinse and rinse and problem has never gone away. If you are familiar with the tank you know you can not use a sealant as it will block off the hose connection on the bottom. Someone has had to deal with and fix this problem. Just about to modify a half gallon milk container and put it in there.
