Message: [QUOTE="elrodalexander73, post: 1142629, member: 16217"] I think it has alot to do with pop off pressure, once the fuel overcomes the fuel needle return spring its under alot of pressure, and once the orfices become exposed the first real batch of fuel is injected, in my opinion that PRESSURE loss is what is causing the HPOP oil drop off, once the orfices become so large with a smaller volume of fuel the oil cannot possibly keep up, because at that point the plunger falls so rapidly into the barrel under hydraulic pressure it causes a rapid pressure drop too quickly for the ICP to interpret. Its like when you first intially pull the trigger on a garden hose, the first split second is water that will travel very far, but once the pressure drop occurs the water returns to lower pressure stream.... SOOOO if we up the volume to a point where we are keeping the volume consistent with our fuel flow we may be able to cure this problem.. I'm probably wrong but who knows, and who's to say if we up'd the fuel pressure to say 80psi and tried that, I mean were in a boat where P'pump is the only real good counter part to making our old school platform competitive, I just wish the darn front covers weren't so darn expensive and time consuming to produce.
