I have decided to install a flop tube in the left tank of my RV-8QB. So far so good. I've installed the fuel sender, the trap door hinge and the flop tube guides. What I need assistance with is installing the actual flop tube. The problem. What do I do with the large thick coating of Proseal that is on the inside of the tank where the hole is to be drilled for the tube. I can't tighten the 90 deg bulkhead fitting that must go through the hole with all the proseal there. I'm obviously concerned about leaks if I mess up the reseal as there isn't much room in there. Secondly, the plans call for locating the hole 1 1/16" from the leading edge. This location might not be the best to avoid disturbing the rivets that hold the T-405 wing attach angle to the wing. Anybody invented this wheel yet?
