New Fuel Sending Unit

The gas gauge on my '89 Jeep Cherokee w/ 4.0 has never read over half a tank since I've owned it. I attributed it to a bad sending unit and just used my trip meter. This weekend I am going to drop my tank and replace my failing fuel pump along with a leaky seal so I want to replace the sending unit while I'm at it. Problem I'm seeing is that NAPA doesn't have a sending unit for it. Where can I find a new replacement sending unit?

thanks,
justin

kragen.com (powered by parts america) has an entire fuel pump assembly for an 89 xj 4.0 for $187.99 it is Master brand fuel pump PN# E7091S Hope this helps.
