I have been custom making some bits, i have made a custom intake manifold (direct feed and front mount throttle body) And to balance it out a bit i want to keep up a slightly higher pressure on the fuel rail. I have an adjustable pressure regulator (a proper one not an FSE thing)
Anyway, Has any one ever fitted one? I have no instructions and not sure weather im suppose to put it before the rail feed, on the return, or disconnect the old one and replace it with this one inline...
Engine is 8v AGG
