    gas tank repair

    Guys I need to get ideas on repairing this tank. What should I do with the fuel fitting? I chased the threads and they are strong,so that's not an issue. But I'm concerned with the seal. Should I try lapping the sealing face? Or should I replace. My concern is if it leaks down the road, I won't be able to repair it as I'm gonna do the "tank renew" process" I talked to "Larry the fender guy" Medwig about doing his silver solder repair. He's talked me threw the process and the snags of silver soldering. below is a few pictures of his repair to an oil tank.

    should I try to lap the seal?
    should I just cut it off and repair?

    Oil leak no biggie
    Gas leak.......well, I would repair as it looks pretty chewed up to me.

    I agree, gut feeling I need to replace it. the silver solder method seem to be the best. Welding is an option, but I don't think it would look factory if I welded it. Just bouncing idea's off everyone until I make the best decision.

    I would go for the silver solder idea, can you buy a replacement fitting from Larry? Or would you have to send him the tank?

    The fittings are the same as the oil feed nipples to the rockers housing. They just need to be machined to fit. I would send to Larry, but he is backed up, and I'm not crazy to sending stuff out to be repaired anymore for time reasons. I just spoke to a guy who restores vintage European bikes in Inver grove heights and he says he does this all the time. But he wouldn't use a soft solder He would use a high silver solder, but he says it's expensive stuff per roll. But stronger.

    I think Larry and Joe are using the same high heat, high strength silver solder. 45%-56% . If Larry was closer, I would be using him. But it sounds like Joe knows his stuff.

    Re: gas tank repair

    I would go with the high silver content solder too. It sounds like you're getting good advice. I've had trouble in the past with the cross-over line from the right tank to the left tank. I've had the fitting crack, and the line crack due (probably) to vibration induced stress. I make that line myself now, and I make sure it goes on with zero stress, or bind. A rubber fuel line would probably eliminate that issue, but that looks like $hit.

    I think that you received good advise. Also with the high temp silver solder you can always repair or replace in the future if needed. If it is welded that may not be as easy to do.

    I wonder if the torch screws up the hardness?

    Low pressure, nothing structural.
    I dont see it being hard in the first place.
    Actually correct me if I'm wrong but they are swaged originally which means they are soft to expand in the hole.
