I know the pump PSI is 45 Max 35 Min, so between 35 and 45 you can best findout by looking on the top of your pump at the regulator. As for the GPH I don't know my guess would be around 40-50 again I have no certain answer but my guess is that. The ohm of the sending unit, well I can't give any exact number or really a guess because each sending unit is different but you might be looking around 250 ohms usually a higher number because if they went to low then the sending unit would get very hot. You could find the 2 wires that lead from that sending unit, it's really 3 wire but one is a ground so I and chrysler drop it off to 2 wires in the diagrams, yea take the two wires and connect an ohm meter to it, if you want I can send you a PDF of the sending unit diagram that will show you the exact wires that are attached to the sending unit, colour coded and all. Just let me know!
