    Not big but there are about 6 of em. I soldered them but was wondering if the gas would eat away the solder.

    I have had great success braising them closed. Much harder than solder but you need acetylene....

    Solder will work, but takes a lot of heat, propane torch should work. Just a matter of getting the gas vapors out. Steel car bodies were soldered for years.

    I just started JB welding all the holes in the bottom of the 185 tank, everytime I think I got them all another one would start to weep. The tanks already got some coating inside. I just ordered a new plastic tank off of ebay. I paid 90 bucks for it and 9.50 shipping. I thought about buying a used tank, but who knows if its not going to spring a leak in 6 months. jim

    They have epoxy putty specifically for gas tanks. It come in a stick about 5/8" diameter. You sand off the area to clean metal and putty over it, wait 24 hours and sand it smooth, and paint. I fixed a gas tank on my '87 Chevy truck almost 20 years ago and it's still holding.
