    I have an anodized alum fuel cell that has a small pin hole in a difficult area to clean up and weld. In rear of car where very hard to remove.
    Was wondering if anyone knows of an epoxy or jb weld type material that will work. And not be effected by methanol.
    Very small hole.

    I used JB weld at the track once on a aluminum tank, was good for a couple years

    I have had good luck with "Seal All", comes in a yellow tube. Most stores have it.

    old school

    the old school trick for this is carry a bar of soap (dad says specifically ivory) and cut a sliver off, then stick it over the hole with duct tape. obviously not a long term fix, but works good to get through a race...

    will not idle down.

    Well best I can figure I have a hat to butterfly clearance issue. Idles at 2200.
    Can't bring down by fattening up bv. Then causing dry sump to overflow.
    Running through 8 gallons in 2 min instead of 7gal in 7 min.
    Idle check is at 65. All flowed by ralph and spike.
    So I am building up clear in carbon hat to reduce tolerance. I had .010 on sides min and bottom alsodo I shoot for zero everywhere.then open to .005.
    So I was wondering is there a trick to tighten up leakage at titanium shaft.
    Just wondering?
    Thanks
