    Just had a situation with my in-tank fuel filter getting clogged ('57 CJ5). After I back-blew it, it cleared but soon blocked again.

    I drained some sediment at the tank drain. Then I also put a donut shape magnet down in the tank, with a piece of stiff wire I can retrieve from the filler neck.

    Once a day I am pulling it out and disposing of the rust particles it collects. No more clogged filter!

    Anyone else tried this?

    Never had an issue. Two filters in the line, Jeep came with new tank.

    Two points-

    - Most forms of rust aren't magnetic
    - If you have that much rust forming in your tank I'd say you probably should yank it & give it a rust-proofing/sealer treatment real soon.

    Interesting thoughts. Guess I should say "rusty metal flakes."
    The tank isn't so bad, just never been cleaned in over half a century.

    PS = isn't ferric oxide the basis for 'magnetic' recording tape?

    Yes it is, that's the form (magnetite, ie. "lodestone" black in colour) that *is* magnetic but it forms less commonly than the non-magnetic types (commonly hematite- the red stuff). This is why "magnetic" water cleaners to remove iron from water supplies are a scam- most iron oxide in water is in the form of hematite.

    Please avoid subjects about Jeep tanks, fuel gauge, etc... It makes me sick.
    I know the problems and I know that it is a delicate matter.
    You shold buy a new one!

    I repaired it many times, but I was twice with an empty fuel tank, and it was each time with my wife, by chance in the village.
