I am currently working on a QB -9 wing, and received a very rubbery (silicone?) type gasket with the fuel sender kit from Vans... after prowling around on the forums, I have read both "throw away the gasket", and "use the gasket, but put a lot of Proseal on everything," Regarding the installation. I have 2 questions... is one method favored over the other, and also, if one needs to remove the fuel sender, will a "hot air type" heat gun, soften the Proseal to facilitate removal, (as is done with epoxy glue)
