a std regualtor is 'linear' rate, so as you increase boost pressure you get a corresponding rise in fuel pressure
eg; 2.5 BAR base pressure at idle (presuming -0.5BAR neg) at std atmosphere would be 3BAR and then with +1 BAR of boost relates to 4BAR fuel pressure

a 'rising rate' reg normally uses a 1.1 multiplication factor so is not linear

Is there a set location for fitting fuel lab regulators or can you fit them anywhere? Car is on standard fuel rails.

Wherever you can safely mount it, but it has to be at the end of the fuel flow through the rails.

I mounted mine here but had to move it to the left slight as fmic pipe was knocking on it.
