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, If you still plan to make any of these, I'll take
a couple...

Thanks,

I am pretty sure it won't take long. All depends on
getting them in the NC lathe job que.
