I posted earlier and forgot to mention What I found with the Pulse Limiter Valve.
I know this is there to protect the VRO pump from a hard backfire I guess my question is what would happen if a PLV is stuck open I removed mine there was no carbon or anything like that but I did find it was stuck open meaning you could blow through from both ends and the valve would not close Would the piston that the PLV is on be able to push a positive pressure back through to the pump under normal running conditions(not back firing) thus creating I guess a lock in the pump causing the pump not to be able to push fuel through.
Does the PLV close on each piston exhaust stroke and open say on the compression stroke to pull vacum and allow the pump to pull fuel in.
If so this would explain alot it would explain why there seemed to be alot of pressure right at the fuel filter.(the filter was clean and un-obstructed)
