Additionally,
anywhere you get an air lock (as opposed to a vapour lock),
you
will have trouble passing fuel, so any unavoidable high points/loops
etc
in the system should have some sort of bleed nipple.
Leon;
My system is
essentially as you describe except my sump is larger (2 ˝ gal). I assume the
above statement refers to ‘before the pump’ because I don’t
see any issue with a high point in the
line downstream from the EFI pump. My experience is that any air in the line is
easily pushed through and past the regulator back to the sump. And why not –
the only resistance to it moving through is the very small pressure head between
the high point and the regulator.
