[FWDLK] fuel delivery problem (2)

[Philippe Courant <accf-club@xxxxxxxxxxxxxxxx>]

Hi,
This evening i made several tests and checks about this *°#"/! fuel line. I removed 5 gallons from the tank (with the electric pump so it works well even to pull 1 ft higher ..), re-tried with pump  attached to sending unit tube : same results: bubbles in the (clear) hose, very little and erratic flow in the jar.
So, late test, i sent 50 PSI in the tank through the sending tube. "vraoum" i heard + noise of bubbles. I re-attached the pump and bingo, lot of fuel ( 5 quarts in 1 mn), no bubbles , etc... So there is "something" in the tank or at end of sending unit which plugs the tube !!

What i don't understand is that the tank was cleaned and coated with special epoxy 3 years ago !!! It wasn't rusty or dirty before but i cleaned it perfectly before coating !!

I haven't yet re-attached mechanical (or electrical) pump to fuel line but i think the problem is solved. But now i must drain the 15-20 gallons of gas before removing the tank ...
