I couldn't find a good way to run fuel lines without using the blisters. I originally wanted to ensure the fuel lines were completely out of the cockpit; however, it was really impractical. I even wanted to install AN6 bulkhead fittings but in the end the simplest way turned out to but like the plans. I bet the 3/8" tubes and ran them into the Hell Hole. I then FLOXed them in place. Once it is dry I will fill the rest of the hole with FLOX and cover it all with 2 PLY's BID on both sides.
