fuel pressure & rail pressure
i have a question about them both, i know i need a fuel pressure gauge because A: i need it and B: im getting a airdog 165. what size fuel pressure gauge should i get and how much fuel pressure am i supposed to have??
Rail pressure.. what is that? do i need a gauge for that as well? and if so what size gauge should i get for that as well.
thank you for your help, im new to this hobby and im learning more and more off of everyone on this site you guys are awesome.

I'm running 20 lbs fuel pressure w/ no issues.
Fuel pressure is what's before the injection pump, rail pressure is after. Too much, and your damaging injectors. Too little, and you have a no start or lack of power condition. Same goes with fuel pressure. Too little, and your starving the fuel injection system, causing damage. The AD165 puts out more volume than pressure because when you have an extreme demand for fuel to the engine, it will keep up.
