Thanks for the update, I was concerned about the width, the good news is that I have got the bolts out and should be reinstalling shortly.

Nicholas,

If memory serves me right the sending unit is on the drivers side of the tank a few inches down from the top.  There should be some nuts on studs that stick out of sending unit.  The wires go the the back of the fuel gauge.   If making sure everything is clean and tight on both ends doesn't fix the issue it could be the sending unit itself or the gauge.

Sending units are known to wear out.  I had to replace mine and it shows the tank to be completely full for the first two hundred or so miles.  By the time it drops to 1/2 tank it is fairly accurate. I really don't let it get to far below 1/2 so I don't know the accuracy there.

The gauge is simply reading a voltage level from the sending unit.  The voltage changes as the float arm swings up and down.  You can take a screwdriver and touch both post on the back of your fuel gauge to see if it swings all the way to the full position.
Hopefully this will make sense and help you some.

Had the same problem. Solved it by finding a loose ground wire next to the tank. Hope this helps.

Thankyou for the info I suspect the issue may be related to something along these lines. Where was the ground wire , left right, front or rear of the tank?

Thanks!!

OK Fellas, I took a short trip and found a few bugs. The most pressing is the Fuel Gauge reads below empty when full. I think I was able to sort this out one time by rapping the side of the tank with a rubber mallet. I tried that this time to no avail.

Any tips on trouble shooting? Also, does the sender come out the top of the tank or the side?

You may want to try Viscone Rv Salvage.  They have several beavers in their yard.  I have gotten parts from them before.

Brian
Sorry I just reread your last post.
The answer to your question is the new torque rod was the same width as the old one and no shims where required it bolted right in no problem.
It is important that the bolts are tight enough to capture the ball between the mounting plated so they can't move.
The biggest hurdle in the replacement is getting the bolts loose I ended up using a torque multiplier to break them loose .
When I did mine I removed all the torque rods and cleaned them all up replacing the dust boots and installed grease fittings on the remaining originals.
The COMMON PROBLEMS article shows the procedure with pictures.

General Discussion / Multi Plex switch cover

One of the multi plex switch clear plastic covers is broken and falls out of the panel.  Does anyone know if these covers are available and if so where.
Thanks in advance.

Ok thanks. I’ll see what I can find out regarding that and eliminate it from the equation.
