Fuel Fluke

From what I am gathering as a lifelong Plumber and Mechanic, the fuel feed is shaped like the letter P lying on its back. If the fuel line is drained it must be filled completely with fuel before it will operate properly otherwise the air bubble will remain in the curvature over the rear fenderwell. Like when you lose a siphon, I believe the fuel filter is filling with this air bubble. I will try to feed fuel from the pump end backwards, seperate the line from the sending unit to bleed the air out and hook it up again to see if this does the trick.
In theory it should work. :read2:
