Hello to everyone!

My names Geoff - 38yo father of 8month old Elizabeth, husband of Cath, owner of a 1999 built MY00 Liberty RX Manual sedan - silver bought new in August 1999 and now with about 130,000km on the clock

By trade I am a motor mechanic although I gave that up 10 years ago and am now a partner in a small family business.

NOW sorry to put this in my intro - but.......

My reason for seeking out and joining this forum is I am hoping to get some help with a problem with my Liberty.

About 2 weeks ago the low fuel warning light  came on when I still had about half a tank.  Then a few days later the guage would just drop to DEAD empty then sometimes come back. 

My training said simple - fuel guage sender unit BUT On speaking to the local stealer I am told they have TWO senders!  One built into the unit containing the pump and another (main) one.  This to me is WEIRD!!! 

They also tell me that there is a notification about some models having a problem almost identical to mine but they wont tell me the solution without running through the entire check (at a cost of $100!).

Can anyone tell me about this "Second" sender unit or advise if they can help in any way?

Love to get some advise ASAP as I would ideally like to solve this problem before I run out of fuel!!

Thanks

Geoff
