The regulator was originally used in the main line from the tank to the car
with a vacuum input for a non turbo car. In that application the more
vacuum it received the more it opened allowing more fuel. In our case we
put it in the fuel return line and connect it to boost. If it opened more
with vacuum it should close or restrict with boost. This increasing
restriction coupled with the stock regulator increasing fuel pressure
results in a even greater fuel pressure, Thereby boost compensating.
Sound good?

John

The regulator has three ports. If you hold it upright there is the vacuum
port on the
S pole and a fuel inlet/outlet on the Npole. To the W or E(depending on
how you hold it) there is the other fuel inlet/outlet. I say fuel
inlet/outlet
because there is indeed no markings. According to CNM it matters which is
the
inlet and which is the outlet but I have never had anyone confirm one way or
the other. The vacuum portion is actually a screw in fitting with a pointed
end going into the regulator. I do not know if the distance in has anything
to do with anything but there is a locknut on it. At the recieving end is
a standard 1/8" barbed fitting. You put the regulator in series with the
stock
regulator. Just cut the return line from the stock regulator and tie it in.
You use the control signal for the stock regulator to also run the Bosch.
This
signal is boost only as there is no vacuum above the throttle plate. So it
only cuts off the supply as boost goes up. I have never got any specifics
about it
but would be extremely interested.
