Bill,

Thanks. Tried that, and it put me on a path. The pressure will go up to 50
PSI if I pinch the line, and that's when I realized that I still had the
vacuum line attached to the regulator. If I pull off the vacuum line, the
pressure immediately jumps to 44 PSI (as advertised).

I assume, then, that this is correct (and -please- correct me if I'm wrong).
As engine load (and fuel consumption) increase, the vacuum on the fuel
pressure regulator decreases, causing more fuel (at the same PSI) to be
delivered to the fuel injectors.

Thanks.

Hi Michael,
Interesting, on a stock Jeep disconnecting the regulator's vacuum
will kill the engine. I think you're going have to call Mopar for their
trouble shooting tests.

Say what?? If I pull the vac line off my regulator (and rememebr to
plug it so there's no vacuum leak) pressure rises to 41-43 PSI. The
engine will stumble a little then smooth out. Replace the line and
pressure drops to 30-31 PSI. It may actually stumble a bit as I
replace the line but the computer seems to figure it out either way
just fine. Pinching the return line will get me up to 90+ PSI and the
engine gets rough but I've never left the line pinched long enough to
see what finally happens - 90+ PSI in a system designed for 40 or less
strikes me as unnecessary stress on the sytem. I can't remember ever
killing the engine except for the time I intentionally held the bleed
button to test flow rate - 0 PSI or so makes for a pretty poor
injector spray pattern.
