Perfect fit
After doing some research, I figured I could handle this job. I got the wheel off, removed the liner and support bracket...and didn't see anything that looked like the part I bought. It took a while for me to locate the last bolt to remove the bracket. My biggest concern was possibly breaking one of the plastic connections. After wiping off almost 20 years of dust and dirt, I found clips retaining two of the lines that needed to be removed prior to pulling out the assembly.Once I removed the complete bracket, I could clearly see the pump. The new one was an exact match and installed easily. I'm going to run the jeep a while and see if this clears the code and turns off my check engine light.When I didn't see the pump at first, I called Dormans tech service number that came with the new pump. The agent double checked to make sure I had the correct pump and gave me some advice on where it was located. So the seller was a big help. The pump showed up quicker than expected. The pump filter on the other hand got held up in transit. After three days I cancelled it and got a refund. The filter is a breeze to change, so if I need one later, no problem.

It fit perfectly on my mother's 2003 Jeep Grand Cherokee, and it's still going strong months later. If it shoots craps soon I'll update my review.
