I can't remember if I shut the truck down when I fueled.
...
Kevin,...
any thoughts to share before I decide to drop the tank?
...
I'm a big fan of "percussive maintenance". If it isn't working, hit it hard with a hammer. If it doesn't work after that, time to take it apart and fix what you just broke, and hope at the same time it fixes what was wrong in the first place.Edit: The float could be stuck? What about trying a rubber mallet bumped up onto the bottom of the tank just under the sending unit? The plastic tank will flex and maybe send a wave of fuel up into the float. This is a guess.
You can take that to the bank. If only my gauge had stuck full or MT, maybe I would have noticed....
I'm puzzled, but it's better than not knowing when it's empty!
It's a science. This is just part of the hammer inventory I keep in my lower toolbox drawer.I'm a big fan of "percussive maintenance".

Thanks for all the help. The service manual is not very clear, but it looks like the pump and sensor are in the top of the tank. "Beat to fit, paint to match" is one of my favorite mottoes, but it didn't seem to work in this instance. There are some trouble shooting steps in the body manual. They are attached.Kevin,
No experience because mines been working fine so far. Here's some info which may help. It's probably worth checking for resistance back to (from?) the sending unit before dropping the tank. Fig. 121 shows an earlier model without fuel pump. Note the comment about open circuit in the wiring. Good luck. vic

Don't do that Kevin!Might just need to bite the bullet and visit the Freightliner dealer. Oh, I even hate to say that.
I've been here a few times with this issue.Vic's diagram says an empty tank reading would be an open circuit so you may be looking for a broken wire.

I found that when this problem happend with my Sprinter 2004 truck 2500 it did illuminate."but the fuel reserve warning will not illuminate."
According to the wiring diagram (8W-40-3) the only connectors are on the top of the tank and at the instrument cluster.

I believe Kevin said the reserve warning was on. That would be an indication that the wiring may very well be OK. That was one of the reasons I said to bounce the bottom of the tank and see if the float might move if an upward wave of fuel hit it. Probably a long shot, but not hard to try.
Since he offered, I think checking in with Wayne would be the next move.

Thanks, but I really want to remind people that it was JD Caples who sent me the books.But Vic, It was your book that helped me with my problem!
Oh, sarcasm... I always appreciate sarcasm. vicYou are correct, oh wise one.
