Fuel pressure regulator - which one?!

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
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
