 How much to make a top part like this Larry?
 I want one now :)
 Two part plunger with teflon O-ring and internal
 O-ring groove. With such a big leak I think the vacuum in
 the upper spring chamber could be lower.
 Can you think of a cheaper way to do it?

 Paul,
 send me your regulator and I make you a top. The screw can still be single
 piece, we just turn the threads off the lower end for the oring to slide
on.

 OK after I get done testing the injectors.

 BTW kill that last message. I made a serious error in measuring.
 It's a whole new ball game.

 Larry, I think a simple hat section cap and O-ring
 screwed down to seal it after it is adjusted may be an easier
 and cheaper way.

Paul, I have the Aeromotive Compact EFI bypass regulator. Do you know if I
will have the same problem, and will your fix work for mine also? If so, you
might want to see how many to make on a "Run" of these. I haven't got to
"engine start" yet but I am getting closer to "making smoke" with the P-Port
Renesis everyday. I should have it running before the snow completely leaves
(around the end of April).

Not to worry. I got it working better. I had the pressure tap
on the wrong port. I lost the instructions and what looked like
the pressure measuring port was not the pressure measuring port.
I notice yours is slightly different than mine and apparently
yours does not have that port. The vacuum is now having a large
effect on the fuel pressure. Here is a picture of my setup as well
as the picture you sent of your Aeromotive PR. I got to get all this
stuff working perfectly before I can test the injectors.

Perhaps Larry can come up with a fix for the vacuum leak that will fit
both of ours. BTW you can get those vacuum pumps in some automotive
parts stores.
