Jim Was Correct, the Bosch Part # I posted does only have 2 ports (fuel in
and fuel out). However, the BCFPR does have the same bosch #'s and 3 ports
here's why: Both MSD and a Custom Network Motors (Starquest Specialists)
purchase the stock fuel pressure from Bosch and then modify it to add the
third port and make it boost compensating. What that means to us is: We
can not just order the bosch part # from out local bosch dealer for about
$30. We can order the MSD part # 2222 from our favorite MSD supplier for an
approximate price of $60.
I have attached some of the old posts for reference.

John
Below is my summation of the MSD/Bosch BCFPR. Below that, is Scott's
Installation procedures for a StarQuest.

In our case we put the BCFPR 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.

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.

This is supposed to be used with the stock regulator not in place of it.
like George described the N9TEx.
I am getting a better idea of the installation procedure, although I can't
confirm this as fact.
I believe this part goes in the gas tank return line and to the intake. It
is described to have 3 ports (all unlabeled) gas in, gas out, boost/vacuum.
The way it is supposed to work is:
On boost restrict the amount of gas allowed to return to the tank, Thereby
increasing fuel pressure.
If this was installed like I described on a N9TEx, Would it increase Fuel
pressure on boost? If it does I am sure it is the same on a StarQuest.
Given it is a 1969 part. Can anyone get it real Cheap? I will certainly
play with it and report back.

Yep, D-jet, i can confirm. My friend had a P1800 and it used thatregulator.
