Full Floater Posted 20 hours ago Share Posted 20 hours ago What kind of fuel supply pressure (from the lift pump, to the injection pump) should I be seeing with an Ambac pump E6? Are we in the 10-20psi supply pressure range? Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/75824-e6-fuel-supply-pressure/ Share on other sites More sharing options...
Freightrain Posted 14 hours ago Share Posted 14 hours ago If I recall mine was 15+ lb when I put a gauge on my 237 when it was acting up. Found out my throttle arm had slipped and wasn't giving me that last bit of WOT. Wouldn't climb a hill to save it's ass. 1 Quote Larry 1959 B61 Liv'n Large......................

Just sayin!😇 Hint also if you want a little more just remove the drain T and stretch the spring!
