EFI Fuel pressure regulator

I want to replace the fuel pressure regulator with adjustable one that includes a guage. The only ones that seem to be available are rising rate regulators (these are the ones sold by RPI)

I'm using Megasquirt on a standard hotwire plenum/fuel rail etc. Presume that I want a flat regulator rather than rising rate? Anyone been here before?

There must be someone other that RPI selling them.

I guess you could use a rising rate one and leave the vacuum input disconnected....

I wouldn't of thought so, because it wont reduce pressure when you are in high vacuum.

Why do you want to adjust it anyway?
Glencoe, sell a 1:1 regulator:

(although they are more known for their rising rate ones). And I dont think that one will attach to the rover rail particulary neatly.

Stevie may have some ideas.

I suppose I could just leave the standard regulator in-place and see what happens. It would just be nice to have some idea what was going on to make setting up the megasquirt fuel maps.
