You can generally find the info you are looking for in most inexpensive manuals such as chilton or haynes, available at most larger parts stores. Be aware though that most low oil pressure conditions are not caused by the pump, but by worn main or rod bearings that allow pressure bleed off.
Sometimes it's caused by hard carbon residue stuck to the pump pickup. Either way, you need to remove the engine oil pan to check those things. When checking bearings, always re-torque them to proper specs or you will induce a failure even if there was no problem there..

I have a 2003 jeep grand cherokee 2.7crd limited

Most larger parts stores carry either chilton or haynes manuals. They are far from perfect and their wiring diagrams are pretty much junk, but overall the do have enough info for most basic and some not so basic repairs. Chilton also offers a download for pay which is better but unless you are doing major complex repair work, likely you won't need it.

Power steering pump

First check the distance from the bracket mount points on the block, to the pump mount points on both brackets. If distance is different then the brackets are different. If they are the same, you may need to either change pump itself to one that matches engine year. However, if there is sufficient room on the pump shaft, any shop that rebuilds pumps can re-position the pulley to your specs, or replace the pulley with one that has a different offset.
