Sending unit fit?

[maddzz1]

Can you use the sending unit from an 88 2.5 in an 89 4.0? What I could find seems to say I could but I would need to put the 4.0 fuel pump on it. Is this correct?

Yep, just did this on my project build. Replaced the 2.5 pump on my 88 with a 4.0 pump off an 89 xj. Just had to bend a little tab on the 4.0's top bracket to make it fit flush on the sending unit.

but will the sending unit from the 88 2.5 fit in the 89 4.0?

They should if they are both out of MJ's. The different tank sizes in gallons only effect the length of the tanks but the height is the same.

 

Someone chime in if I'm wrong.

Here's the data from the parts manual. Different part numbers for the sender according to tank, engine, and year. What the differences are? :dunno:
