fuel sender not responding on Sahara
'What is best replacement for bad sender. I would like to keep guage working .Any external sender unit?
Any easy engine fuel line and fuel return line measurement devices that could be installed with another guage?
Anyone replace sender unit?Does front axle have to be dropped?
Thanks in advance for ideas.'

'I found the VMSPC unit to be an excellent solution:

Or you might also look at the Scan Gauge:
http://www.scangauge.com/
There are a number of threads about the fuel sending unit and associated problems on the board IIRC. My rig had the sending unit replaced before I got it and it still is a pain. I suspect it is a grounding issue as someone else mentioned above. There are VMSpc threads on the board, I am not sure if there are any on the Scan Gauge.

Re: fuel sender not responding on Sahara
'From my Bayliner Owners Boating website - doesn't have to be the sending unit (or worst case). Tap on the gauge and see whether it moves. These instruments aren't that high a quality that water or humidity doesn't hurt them.
A more difficult way to test the same is to disconnect one of the wires at the sending unit and if it remains on 1/3 you know it's the instrument.
The sender is relatively easy to change if it's the culprit. There's a plate with the sender mounted in the tank. Unbolt it and bolt the new one in. Make sure that you don't generate sparks while the sender hole is open. Don't want to read about you in the newspaper. The senders have a generic mounting plate and all you have to know is the height of your fuel tank. Available almost at any boating place. No need to pay the dealer prices.

Re: fuel sender not responding on Sahara
'Forgot to add, I did the test that I posted and determined that it was the sender unit. I then opened that plate hatch and discovered that the arm the float was on had rusted and broke off nand the float was "floating around in the 80 gallon tank" and I fished it out. Replacement of tank float are rather straight forward, just follow the instructions for adjustment. My hatch/tank cover and gasket looked symetrical but turn out that it was not and I had to try a lot of different positions before everything lined up. I would suggest that before you take it off (unscrew it), use a marker on both the cover and gasket.

Re: fuel sender not responding on Sahara
' Thanks for the info.Unfortunately this is in a diesel pusher motorhome with the tank mounted above the front axle. Major job to drop the tank even enough to see the sender. What I need is an outside the tank measuring device. Does 96 Sahara with Cat 3126 have connections for Scan unit under the dash? Does Scan unit work on plug in engine service bay? Thanks for info.

Re: fuel sender not responding on Sahara
'If you have a CAT 3126 engine, VMSpc won't help with a fuel guage problem, since the CAT ECM does not measure or transmit fuel tank information on the data buss that VMSpc uses. The ECM measures each tiny dollop of fuel sent to the injectors and adds them all up in order to keep track of (and report on the data buss) the amount of fuel used.
