If you mean the pressure at the fuel rail, I just looked it up for another post, and for a 4.0, it should be 31 psi at idle with the regulator vacuum line connected, and about 39 with it disconnected. This appears to be the figure for both the 87-90 Renix system and the 91-up Chrysler system, although they use different injectors.

The injectors are rated at about 19lbs if that helps any.
