Your fuel pressure regulator is actually part of the fuel filter assembly located in front of the fuel tank above the rear axle. Finding that hard to believe it is two in one, I sawed the old filter assembly in half and sure enough, there was the filter and the pressure regulator. And I found that part on Ebay for only $15 and replacing it actually made my 1999 Grand Cherokee Limited run better and get better mileage. This should be done every 50,000 miles or less. I hope this helps.
My dad said his 95 grand Cherokee fuel regulator goes on top of the fuel pump in the gas tank
GuruWH611, You are correct on the location of the fuel pressure regulator on your Dad's 95 Jeep Grand Cherokee, but I think Molly is asking about her 2003 model year. The WJ Jeep was 1999-2004 and they were fundamentally the same. But thank you for your additional information. A lot of those 95's are still on the road and running strong.
