Hi everyone,
Thought I'd post up my ordeal to help others out.
Recently I purchased a '91 XJ. The fuel pump would start whining - usually after about 30–45min of driving. So I decided to change out the fuel pump this weekend. Turns out, the PO had installed an Airtex pump.
I first purchased the following:
Spectra Premium SP7091H Fuel Hanger Assembly with Pump and Sending Unit
Amazon 'confirmed' it fit a 1991 XJ.
Upon installation, the fuel gauge was reading opposite of normal. My fuel gauge increased the more fuel was spent. This is because Jeep reversed resistance in the sensor in 1991 as far as I can tell.
So I immediately pulled that pump assembly back out and went to O'reiley's. They sold me a fuel pump with assembly under the brand name "Precision". I brought it home, took a second look, and noticed there was another sticker hiding under the Precision sticker. Turns out, it was an Airtex on which they just slapped another label. Precision = Airtex. So back to the store that went and returned it.
Finally, I went to Advance Autoparts. They sold me a Carquest pump. Upon testing the float it read correctly on the dash.
No matter what I tried I couldn't get it to sit flush against the tank. I reached into the tank and pulled out an old grommet, but it still just did not sit right. Eventually i forced it into place and put a lock ring on. It is now weeping fuel a bit. I am hoping it will stop after some time, or I will have to pull it all back apart again.
Hope this helps someone in the future.
If anyone in Colorado needs a 1990 or earlier fuel pump, I have one that was only installed for a few hours.
