Lund... Venom 320cc pintle type.
BTW, do you have a std. 255lph pump or a HO 255lph pump (That's GSS-317 or GSS-342) ???

Zeus... Wednesday is better than NEVER. I sure could use your input.
Turismo... The adjustment screw that I referred to is only found on the B&M Command flo (which is essentially an adjustable "top" for the OE regulator) or the new Vortech unit. If you do not have either of these, it is OK... your heart was in the right place. If you do... well do the test and hit me with your findings PRONTO !!!
Thanks again to all.

When it pegged my Autometer, I looked around in my Dad's stuff and found an old Stewart Warner pressure gauge. I don't know what the original application was. It looks like it should be in a real old cobra or something with a big steering wheel!
One thought I had Jim, was I used, and you may have also, the JR brass fitings from the JR unit. These are smaller, and maybe too restrictive to lower pressures down. One would have to get larger tubing for the fittings that came on the cartech. The JR ones may be to restrictive.
We bypassed the JR regulator all together. Still stayed at 40-42 psi. Any other thoughts guys??

Are you sure the restriction isn't in the fuel rail? Try doing a straight plumb to the return. That's the only way that you'll find out where the bottle neck is.
Well we replaced the factory fuel rail with a new STR fuel rail this saturday. It dropped the pressure about 1-2 psi at most.

Did you try to replace the vacuum lines with the shortest possible length? Sometimes the lines are weak or soft and crush from the vacuum and restrict the line. If the regulator doesn't see full vacuum at idle, it won't give you a true reading.
Can't hurt vacuum line is cheap..
If the restriction is the return line, you should try the direct hook up just to see. I don't have a situation like that at all on these cars. Ones a 95 GSR and the other is a 98 R Type with a lot of rework. Maybe newer cars are different?
Maybe I'm thinking wrong here but if the using the Cartech by itself wont let you lower your pressure as low as you desire wont you still have the same problem as with the JR unit?
Wont the lowest pressure obtainable be determined by the most restrictive part in line?
Did you hook a straight line to the return (no regulator) to see the lowest possible pressure?
Maybe it's the volume the HO pump puts out vs. line size and the stock pump's capability.
