My OE shower heads lasted 24 years (can't complain about that) then melted away and fell off into large pieces.
I pulled both tanks and just added the 'proper-submersible' fuel line.
While the tanks were out I gave the outsides an acid bath to dissolve any rust then neutralized the acid etching with baking-soda and water then, fully painted the tanks with rustoleum.
HOWEVER...on the outside of the fuel tanks I did add an inline filter...reason...if I added some type of filter/screen on the inside and it became blocked I would have to drop the tank to remove the debris!
With the inline filter on the outside of the tank that allows me to simply remove the filter.
BTW I used a
WIX #33972 transparent filter designed for diesel fuel.
