Jay, I removed the fuel rail from my friends (Judd)  3B & my own, purchased & modified a pair of metal valve stems, drilled holes in the top/center of each fuel rail, Judd silver soldered the stems in place reassembled both vehicles.

Now fuel pressure checks are quick and easy.

I just did some poking around the fuel system on a warm start issue. 
Cold start is fine although there is a slight idle variation adjustment 
cycle right after start and it seems to almost dump it's idle on some 
couple minute schedule and recover and run normally.

I tried to find a way to adapt my CIS pressure gauges to this car and I 
couldn't find a way to do it with the adapters I have.

I cracked the fittings on the fuel filter to check if it was restricted 
in any way and it wasn't but there was no residual pressure with a few 
minutes of running normally. I think this points to my brand new fuel 
pump check valve being stuck open again or maybe has a flake of 
something stuck in it.

The question is can the fuel pressure regulator stick open and kill rest 
pressure? Will get a gauge set as soon as possible to verify and I will 
take the FPR off as well to inspect.
