Thanks I hope I don't need to if it happens I will try the MT-2500 idea I have used a faucet washer and self tapper on metal tanks. When I had a garage you don't want gas dripping on the black top parking lot. You definately don't want it in the garage with smoking mechanics. I've caught them smoking when putting a fuel pump in.
Just getting to a junk yard and scheduling the work takes some time. I don't do work when its above 95 or 100 degrees.
Thanks again
