Epoxy does not break down when fuel is splashed on it, or when hot exhaust residue hits it. And the oily mess won't usually affect it over a few months.

But put epoxy under fuel or where it's exposed to it for long periods of time and it will break down. And J&B is basically a metal filled epoxy.

If you don't expect to use the fuel tank for very long, the J&B should work for awhile.

I made some fuel line plugs by dipping the ends of 2-56 bolts in J&B. The J&B was basically to give a bulge. They worked for about 6-8 months and I started getting crap in the fuel. And one day, noticed when I pulled the plug the end stayed in the fuel line. And when I picked it out with a pin, it came out is bits and pieces.

It is fairly simple to solder to the can. First empty the can of all fuel and leave rest to evaporate. Blowing some compressed air through it should help speed the drying. Conduct all work with the cap removed. If some stray fuel ignites then the pressure has somewhere to go. With fine grit paper, sand the can shiny and wipe down with cleaning solvent to remove grease. Drill a small hole in the can, hole should be smaller than brass fuel tube. Then push a nail through hole. The nail so be such that the diameter is slighlty less than brass tube. Shine up the brass tube similar to the can. Tube should be a snug fit. Apply some flux, heat, touch some solder to it and you have a great connection. I used a micro torch and it worked great. To ensure that the heat did not discolor the paint on sides of can I wrapped a damp washcloth around the sides.

However you will burn the paint if you solder directly to it. I added two brass tubes to my can. Both enter from top. The front one goes to the bottom of tank. The end of this tube is cut at a steep angle so the bottom of can will not suck into tube. This is connects to the suction side of my electric pump. The second tube just penetrates the tank and is the vent.

This got my fueling connections out of the cap. This makes refilling the can easier and cap is easily removed to inspect for remaining fuel level. I also wanted a way to easily check the fuel level. I did not want to damage paint on the side of the can or distract from its appearance. I have found this to be an acceptable solution.

Take Scott's idea and do it to the side top & bottom and connect the metal parts with fuel tubing and you will have your fuel guage. HTH Philip

neat idea Scott

I am looking for the solder as we speak [:-]
