    Sounds like the tank had a sealer in it that has failed, if this is the case it will have to be stripped internally and be recoated (bill hirsch makes a great kit) and is the only one ethanol proof

    Sounds like Red Coat.

    We sublet our aft axle diesel tanks to a radiator shop that recoats them with Redcoat. It seems to hold up pretty well, but I have heard one of our customers say that it can still delaminate. We don't know for sure what causes it but I would suspect it could have something to do with ethanol or the newer diesel additives, or both. I haven't heard of any issues with gas tanks though, so it might just be the diesels with the issue. Yours might not have been prepped properly.

    I believe prep has alot to do with it also. And maybe if it isn't completly coated the fuel can work it's way into the edges.
    I believe it requires some mods. There are tech articles that show how to install newer Mav tanks (not sure what year) that are available. I myself should and may do that once my car is running. I remember it didn't cost much just have to do the mods.

    Prep is key, avoid water cure tank sealers

    I think I paid $3.85 for the longer carriage bolts holding the straps...and around $10 for a new vapor valve. (y)
