Disassembly cleaning wing tank KITFOX3

[ChrisKitfox]

Hello, we found during the andoscopic inspection of a wing tank of my kitfox that the coating in the tank was detached and decomposed.
You could see the photo joint.
Has anyone ever had this problem? Disassembly, cleaning? Your solutions?
Thank you,

Chris

To me the fuel system is way too critical of a safety item to mess with trying to fix the problem you have. My opinion is to replace the tanks with the new alcohol resistant ones.

I second that notion. Replace with new tanks that you don't have to worry about ethanol hurting them.

It is clear that it would be best but I do not know if I will find the tanks for my model. I do not know if it's fiberglass tanks

Do you have the procedure for this replacement? Instructions? photos? tutorial?

Does kitfox sell them for your plane. If not I would pick brandon’s brain on maybe modifying the tanks they sell to make them work in yours? He would be the best resource as I know brandon told me he spent a lot of time researching resin that is safe with ethanol.

I believe others have used acetone (or something) to dissolve the Kreem fuel tank sloshing compound and recoated their tanks with that or some other tank seal compound. If you do a search in the archives, I think you can find posts about it. That would be my first thought on how to solve the problem. JImChuk

PS, what were you trying to show in the second picture besides the disgusted look on your face?
