[Public-list] air in fuel lines

[Mike Lehman]

Is this a diesel or gasonline?

If gasoline, then your fuel pump is suspect.

If diesel - the check your fuel lines and how they are led. I had a similar 
problem which was corrected by re-leading a fuel line that had a dip in the 
line. Air would collect in the dip and eventually make its way to the 
engine. It was a bitch to trouble shoot. I rebuilt the racor, tightened all 
of the connections, changed filters, replaced the fuel pump, etc...and all 
the time it was the dip in the fuel line.

I have tightened all clamps on fuel line fittings going to the filters and 
pump.  I also installed a priming bulb in line before the main filter 
(racor) and can not eliminate air in the lines after running the engine for 
a few minutes.  When it shuts down I squeeze the priming bulb and it opens 
with some force as there is suction from the pump.  I have removed the line 
from the carb inlet barb and activated the pump and there is plenty of 
pressure.  I bypassed the main filter and still the problem exists.  Only 
thought is my fuel pump is not putting out enough pressure or a hole in the 
pickup tube.
