After a lot of hand wringing on how to create a removable loop in the main fuel line, for fueling the tank, I came up with these ideas and settled on the brass loop. That’s the right hand image below. The main fuel line from the tank will project out from behind the engine flex mount, connect to the loop and then another line will go back to the pump. The loop will be easily accessible behind the engine. I didn’t have much luck bending the brass tubing into a loop, so I cut up three pieces and hi-temp sliver soldered it together in a loop. After cleaning and polishing the outside of the loop I ran it through a ultrasonic cleaner a few times to make sure the inside of the tube was clean and pressure tested it under water.
