21006, hrc fuel pump and stock fuel pump setup questions
Posted by jamesman, May-01-02 04:41 AM
okay i got a question, with the hrc kit on our car when the HRC pump exceeds the flow of the Stock intank pump does it suck fuel through the intank pump or does the intank pump have some type of bypass that the HRC pump pulls fuel through. the reason i ask is because i have this damn awful loud vibration noise when my car reaches 6 psi of boost, it is not RPM dependant, because i can produce the vibration at any rpm, as long as the boost is at 6 psi which in turn is making me think it is from the fuel system because the sound seems to be coming from under the passenger seat area where the hardlines for the fuel are. i am not using the stock fuel lines, i have -6AN lines from the fuel pump to the filter then -4AN from the FPR back to the tank. i think when the fuel pressure reaches a certain pressure at 6 psi of boost it causes this noise i really hate it it is really loud and it makes my car sound like it is going to fall apart it is a high frequency noise.
sorry so long
thanks
james

well if you think that is the reason, then swap out the stock for a Holley or walboro and see what happens. Better to run two pumps than one.
Hey you still have those 315 injectors?
