my 2008 200 hpdi Vst pump, (some say medium pressure pump some same hp pump) anyways, im having a problem once the motor gets hot, it boggs down for a few second as soon as i break pad, then she cleans out and runs great. so i put a fuel gauge on the vst shradder valve and im only getting 18psi (very slowly 5 seconds) with key on as well as while idling as soon as i turn key off the gauge falls to 0psi. I tore into VST pump to inspect and everything looks good, put it back together and only getting 12psi now. might i add the motor blew recently and i had a complete new powerhead put on, all new fuel lines, filters and tanks scrubbed. so i dont think theres and fuel restrictions due to filters etc. the vst filter was clean when i pulled it.
does anyone have any suggestions as to why im only getting 18psi other that the pump being shot? can it be anything down the line thats possibly causing this? I pulled the line going from lp fuel pumps to vst to possibly rule out a vacuum.
any suggestions would be greatly appreciated before i fork out the cash for a new pump, goodness they are expensive for what they are.
