Here is a part you are going to need if you run Tracy's
 EFI system with a p-port. This screws into the apex
 seal oil injector port. It has a 10 mm 1.25 thread.
 The hose barb is for about 3/16 ID vacuum hose.
 The small hole is about .050 diameter to damp the
 pressure pulses. This works like a charm and it is possible
 to idle the p-port down to about 1500 RPM.

Paul, would this be an appropriate place to get the pressure feedback for
the fuel regulator, or is somewhere in the intake resonator still most appropriate?
C. Smith

Yes. Ideal place. I would tee them together for the fuel pressure regulator.

One hidden advantage to this is there is nothing on the
SS tube that could interfere with the sealing collar that slips around
the outside of the tube.
