cjomanche Posted March 31, 2017 Share Posted March 31, 2017 Hi everyone, so I bought my first MJ last night! Excited to officially be part of the club now. All the gauges work, even my fuel sending unit, but I'm paranoid about this specific gauge and I would love to have a spare just in case. I'm finding 3rd party ones on carid that say they fit but it also says it fits XJs so I don't think it is the right part. Does anyone have one they can help me out with? Thank you Link to comment Share on other sites More sharing options...
Keyav8r Posted March 31, 2017 Share Posted March 31, 2017 Sending units for our trucks are not commercially available. The XJ sending units are not a replacement for the MJ units as the float arm is oriented in the opposite direction. I believe there has been a post on modifying the XJ unit to work in an MJ but I'm not sure it was specific to the 91 model year. I obtained a sending unit from a 91 XJ and mounted the sending element on my 91 MJ pump and sending unit bracket to replace the original unit that had failed. The ohm range is slightly different, but close enough to work. For more accuracy, you could get a fuel gauge from a 91 XJ and replace the gauge in your instrument cluster. As you are looking for a spare, you have time to source the parts from a JY and then do the conversion when your unit fails. I'll locate the post and send the info to you.
