Almost got all the bugs worked out of my rebuild. When I bought this project, I received in the box o' stuff a rebuild kit for the petcock. After rebuilding the petcock, still leaking.
Off to Z1 Enterprises for one of their universal petcocks. This is where I ran into a problem.
Not being mechanically competent, I tried to get the universal petcock to fit. When I realized that the reservoir was a little bigger than the stock opening in the gas tank, I took a flat head screw driver and a hammer and tapped one side in until the reservoir was clear and I was able to attach the petcock to the gas tank.
This is where the trouble begins. I warped the metal on the gas tank by hacking the opening to get the reservoir to fit in. The surface is no longer flat and I cannot get the leaks to stop because of this.
My question is, can I use Permatex Liquid Metal Filler to level out the area so that the petcock seats perfectly again to the bottom of the gas tank?
Has anyone even tried to do this? I received a suggestion that I take an old inner tube and cut it to twice the size of the O ring and place that between the tank and petcock. I still have a small, maybe 1mm gap that is leaking.
The Liquid Metal Filler is gas and oil resistant and I figured that I could use this in the same fashion as bondo and smooth it out and then sand it to seat properly. I still plan on using the O ring and another piece of the inner tube to make a good seal to the bottom of the tank.
I already tried to use a gas and oil resistant sealant, with no success.
I'm just wondering if someone here has tried the liquid metal filler and had success with this.
And, if so, any suggestions on how to do it right the first time? I'm thinking of putting a 6" bead of this stuff on some aluminum that I have laying around and playing with it a little bit so that I know what I'm dealing with.
