Idles fine - runs for short period at WOT then Bogs down like fuel starved vacuum/pressure gauge reads nuetral on engine side of fuel filter at WOT
needle shakes at idle
Same on other side of white metal critter that fuel passes thru. Assume this may be low pressure pump Excess seawater passes through this thing I beleive and exits as confidence stream

pressure on shrader valve on high thing is 40 at idle 60 at wot

Spec on page 3B-1 of previous manual says I need 3-6 psi between vst and low pressure pump
looks like a pump rebuild
