Ron, Quick thought. If the engine ran before the rebuild with the mechanical pump, it should now as well. Be sure to double check what ever drives that pump to be sure it is right. Just an old mechanic thinking..........
I also tried the balloon method, bud I didn't like the cracking and popping noises coming from the tank. I probably used a bit too much air pressure. Anyway, about 16 hours full of fuel with out any leaks makes me feel good about it.
Well, my fuel cell held fuel overnight with no leaks! After trying to come up with a way to air test the fuel tanks, I asked Ron what he did and he just filled the tank with fuel and checked for leaks. Keep it simple stupid method worked great! Now to install leading edge plywood and this one is ready for fabric.
Today we took the wings off to begin fabric soon. Put the fuselage back in the rotisserie to work on the new landing gear fitment. The gear is a real piece of artwork, so happy I upgraded! Finished epoxying the flaperons. Thanks to Ron, I have a nice Magnum wing rotisserie to use!!
