Not Ranked
now I'm confused.........
G'day all did a bit of testing on the fuel system but now I am not sure where to go look next. 
The Ford manual specs for fuel delivery in an AU say -
min delivery 240cc in 10s (1.44L/min) @ 275kPa, pressure at idle 225kPa and stationary pressure 275kPa
I measured approx. 2.15 L/min (approx 130 LPH) fuel delivery off the return fuel line and pressure tested at 325kPa (3.25 bar) at idle and 340kPa stationary with no loss of pressure from the fuel rail.
The Bosch 044 pump is rated at 300LPH free and 200 LPH @ 5 bar, so it seems the pump may not be delivering at its rated capacity but its delivery is in excess of standard AU specs.
So what might be causing the fuel starvation I seem to be getting?
I'd cleaned my filters prior to this so there is no issue there and my only test of the Carter feed pump was out of the car but it delivered at an unmeasured but seemingly high rate without noise or complaint.
Where should I go looking now? Any suggestions?
Cheers
