Low fuel psi WOT
#11
R&R'd the HFCM today. The old unit had some brown stuff in the water separator, probably algae, but otherwise clean. The fuel pump itself was a goldish color where the new one wasn't. Different mfr? Excessive heat? The new HFCM didn't have the heater and was loaded with a filter.
At idle/cruise, psi was still 60~64, at WFO, it never went below 50 psi, even when the speedo went back to 0 after hitting 100 mph.
