Ed, The flow path goes from the inlet into a holding area under the computer, I will call it the " cooling chamber". All the electronics sit on the metal bottom (heatsink) of the plastic computer. More flow the better the cooling. If the overflow is closed then you will only get as much flow as the VP44 is using at any point. no way around that since there is only one way into and out of that "cooling chamber". the flow input from the holding area is pretty small too, no amount of 1/2" hose is going to flow more since the restriction is actually the passageway going out of the "cooling chamber". I would say and I think Mike will agree that above 14 psi is still what is called safe when it comes to cooling defined fuel path will be good though. Now I would guess that most of the timing failed pumps P0216 code are due to bad timing pistons. Thanks Nick
