If you’re changing the lines, it can’t hurt to look at the fuel sock on the pickup. Rust in the tank can accumulate on the sock as you drive, building up even to the point of a stall. Once the suction stops, the rust flakes fall off and all seems just fine again for a while.

I usually put a couple of strong magnets on the bottom of our old cars’ tanks, but out of the path of the float arm. It helps keep the rust away from the pickup.

On one particularly rusty tank, we removed the sock and installed a transparent glass filter in the fuel line close to the tank. It was easy to spot and clean the accumulated rust out before it could continue to cause problems.

There is an old-school tank rust removal of adding a gallon of acetone and a length or two of chain, then agitating it for a while. It won’t make it shiny and new, but it does remove the loose rust scale.

Some things to consider if you end up dropping the tanks.
