Tip: Caution with fuel line-walking area
 

When you run your fuel lines to the wing (and if it's going to be awhile) leave enough line and or bend it flush with the fuse so you won't bump into it. and possibly kink it.

Fourth time around, for these lines. (another story, chaffing when shoving)





edit-- "I didn't need this!"

Alternate Solution
 

We ran a 90 degree bulkhead fitting out of both the fuselage and the tank. We then used a flexible steel braided line long enough to be in the shape of a light bulb and avoid a kink. Works like a charm and with better than a hundred hours no issues whatsoever.
