jb weld

[Anonymous]

What have your experiences been like (both negative and positive with jb weld. I would like to mount a fuel tap on an aftermarket tank using jb weld. I have to mount this fuel tap at the back underside of the tank due to the angle atwhich the tank mounts to the back bone of the frame. I had previously had a peice of 3/8 brake line bazed in the smae location but the line broke where it had entered the tank. I suspect that too much heat was applied to the brake line and it became bittle.

Thanks in advance

It's not that great of a material for building up an area. I tried to fix a boat motor that had had it's bottom hit against a rock and after a year the JB weld dried up and shrunk.

I have had good experiences with JB Weld. I think the key it to be realistic about the product your using. Its not steel. It isnt meant to hold up to tremendous punishment or loads. Ive repaired cylinder heads with it. Hell the
gas pedal on my 88 Dodge Power Ram has been held on to the fire wall with
that stuff and that was 3 years ago.... Point is if you clean the surfaces good of what your working with and mix the JB Weld correctly, and allow at least 12 to 24 hours to set and cure it will hold up well..

Least thats been my experience with the stuff.

Have a plate welded to the tank that you can tap so you can bolt the petcock on right. 1/8" thick with a good smooth weld all the way around should do.

Someone slaped on a cheap petcock on my bike and used JB weld to fill in the holes and seal it all up. For the most part it has worked ok. It has leaked and more JB weld stoped it. However, I am replacing it with a Pingel to be safe. I am sure that someone makes an adaptor that will fit your tank that will allow you to screw the Pingel into.

JB weld does soften in gas, so using it on a gas tank is a temporary solution only.

I have used a product called marine tex. It is a fiberglass based product found at marine shops. It will hold on your fuel tank. Its almost unreal the things I`ve seen that stuff do.

I don't think I'd take that chance and become a flamming hot dog on the freeway someday. Maybe you can find some fuel fittings and use some safetywire to guide them to the hole inside the tank and then be able to screw the outer nut with a seal on for a leak free tap.

jb weld

your right, I don't want to end up a flamming hotdog on the highway. My life is challening enough as it is. I went out and got a fitting silver soldered onto the tank.

Thanks very much for your input guys.

Pingel sells adapter plates for their petcock that will fit all the GS models.
(different plates)

I used a two part epoxy putty, the kind that comes like two colours of plasticine in a strip, to repair a hole in a gastank once. It worked brilliantly for over fifteen years, but there was no mechanical stress on it.
It was advertised as being specifically for gas tank repair. It's still available. I'd give it a go on the side of the highway in an emergency, but it would be way safer to just get it fixed with metal, the way it's supposed to be.

I second the advice to weld on a plate. A local welder can do it, and probably just a couple of bucks.

Get a plate of the appropriate size, and make the mount holes for the petcock. Once that all lines up well (try it against the tank to make sure it flushes well) then take the plate and tank to a welder.

Wash teh tank out very well, and let it air out well. The welder will likely ask about this, as few people like to be sent to the moon unexpectedly while welding.

while washing it out with water will make the owner feel better but not the welder .i am one and i do have the t-shirt. i always purge the tank with argon or co2 to deplete any oxygen inside the tank .no oxygen = no fire
