Thermoquad fuel bowl cups?

No. don't do it. JB Weld is NOT impervious to gasoline. You need to use a two pary epoxy that is. JB weld is not. It will work short term,but it will eventually turn loose.

JB Weld I use is a two part epoxy. However what would you suggest using?????

Do you mean "turn loose" like the stuff Ma MOPAR uses!!!!!!
