I have a 1981 XJ6 and the right fuel sending unit is out I am going to change it out. Can you change it out from the tail light section or do you have to drop the fuel tank? Thank Jerry

 

Mine (series 2) is accessed through the tail light, I don't know if that changed with series 3.

Tail lights are easy to remove and take a look. You might be surprised to find it's only a matter of the ground wire falling off. There's a rat's nest of wires there, for the tail light complex, marker lights and the fuel sender. They all share a common ground through a bullet connector. At least mine do.

If you decide to remove the sender be sure you drain the tank below that level before you break into it though.

Yes, it can be done through the tail light! Just don't make the mistake I made, make sure tank is almost empty when you do the job! I posted about what happened to me in a post that is labeled "engage your brain before working on your car! "
Cannot link to it from my phone, just know that a garage floor flooded.with gasoline is scary indeed!!!

 

I have already drained the fuel tank and removed the sending unit which was rust up and frozen. It is just holding in the new sending unit and then trying to put the twist lock on at the same time looks tricky. Thanks for any input...Jerry

 

Yeah, it is a twist and lock device.


Elegant. Find a large worn out socket. Grind it with gaps and teeth to engage the lugs on the sender. Offer it up, push and twist.


Not so much: a chunk of tubing with the end cut to fit the lugs. Perpindicular hole for a lever to twist.


Not sure if there is enough room for a brass drift to drive the lugs home.
