Curious if any A&P's can identify the cause of this stain from a similar experience. Plane has set a number of years without flying.

Leaky bladder. They don’t last forever and changing them isn’t difficult or unusual. Odd color for fuel stains. Avgas blue dye is what you’d expect to see residue from. The stains might buff out. Hard to say from the picture.
Wow you all reply fast! Thanks for the input I know it was found to have 100LL in the tank. Not much of it anyway. Its a late model 1974 172M.

when the tanks are fixed let us know we can fix that paint problem.172M has aluminum tanks that crack. It also has lacquer paint that runs like that. Fist thing, though, is to check the gaskets at the fuel level sender and filler neck. Filler neck requires that the top cover comes off the wing, which could be interesting if it's never been off. The screws could be rusted in the anchor nuts in the wing, and could break off. The nuts along the front are in the spar and their rivets are under the leading edge skin. Very time-consuming to fix.
