while my gas tank gently seeps

[speedlimit85]

Still leaking! Looks above the petcock. Is it the tank? This sucks.

[speedlimit85]

Or the sending unit?

[speedlimit85]

the sender unit bolts have the same washers as the petcock screws

be working on that when the gasket arrives

I've seen a leak on an 80 Standard, it was coming from the seam on the bottom center of the tank underneath the welded on mounting tab. The fix was to use a small amount of internal tank liner only in the rear with the tank tilted upright to let it cure. I hope that isn't the case for you.

[speedlimit85]

It is. I stripped the tank ( gonna brake a g string). what kind of internal tank liner?

[speedlimit85]

Caswell epoxy? J-B Weld Tankweld Repair Kit..?

[speedlimit85]

Is solder an option?

[bikerphil]

If you can see the hole, you should be able to use a soldering iron. DO NOT use a torch. Maybe someone will chime in on a good tank liner to use. If the hole is under the mounting bracket, the tank liner would be a good option.

Alright there are options. A friend works at a garage. We can inspect it better today.

leaking from the edge of the bracket

[bikerphil]

Yep, that's the place I mentioned, under the bracket. You could try some kind of patch on the exterior, but I think some tank liner in just that section of the tank would be the way to go.

Or you could replace the tank but these Standard tanks are getting harder to find, and can be pricey. May be a good time to upgrade to the larger capacity Venturer tank if you can find one. Just thinking out loud here.

[speedlimit85]

A 6 gallon would be nice...
