Are you wanting in tank or on the frame for the pump? Autozone has the in tank for the 22RE for 130.00 but you can probably match the PSI and flow rate to one that mounts to the frame for 80.00 - 100.00. I bought an E2000 pump for 90.00 from them that is pretty small and works great. Looking at the stock pump specs it puts out 60-95PSI and the E2000 puts out 70 - 95PSI so it should work for you except the gallons per hour is a little less on the E2000.

that sounds like it would work, is that what you are running on your jeep?
From what I've seen most just cut the hole and use a Toyota pump and lengthen the pickup tube. I wouldn't spend too much time or money on it if your like me and many others you will learn to hate the RCI aluminum cells
