Fuel pressure regulators:
There are two types of FPR's. Dead head and bypass. The cheapest by far is a dead head regulator. This is the type of regulator that comes with a Holley blue or red pump. A lot of people will tell you that they work great. Blah. All those POS dead head fpr's do is create back pressure on your fuel pump which not only causes inconsistent fuel pressure, but also dramatically reduces pump life.
Bypass (return style) fpr's are better in that they not only significantly reduce back pressure (the fuel pump will live a longer life),but also help produce a more consistent fuel pressure. BUT you will have to run a return line back to the tank of at least the same size, but preferably a larger ID.
Yes you can you a return style regulator with any electric fuel pump.black90gt5.0 said:i thought you could use a holley blue with a return style system. mine has to ports out, one port in. what is the second out port for?
