Well what is the deal with this (just sorting out my fuel system)

Are there electric FPR's or just vacuum driven?
if so anyone used one?
Do many EMS's have the ability to control this?

Thanks

Joe

The fuel pressure is required to change due to the changing manifold pressure. The more pressure in the manifold the more fuel pressure is required to push the fuel against it, and vice versa.

Controlling it electronically is adding a level of abstraction (pressure->electronics->actuator) that isn't required.

Regards,

Dave

how does the regulator know what sort of pressure that is going on in the manifold is that by a vacuum line from the manifold?

Yes.
