Good day everyone. Fuel sending question. First things first. I have a 2004 Monaco Lapalma 36 dbl. on a w22 chassis, 8.1. Enough said. Gas gauge not reading correctly. Where is the sending unit located and is it adjustable. Or is there an adjustment through the dash cluster? Any info would be helpful. God Bless everyone.

My 2000 Monaco Executive suffered the same problem. IE...needle bouncing around, inaccurate readings. Very simple fix. Locate where your fuel tank. Open panel to get to tank. Your sending unit should be on top of the tank, (round puck like object with wires running from it). Find the model number by searching sending units for your rig and order that one. There is a place out of Michigan that builds them. 10-15 minute job.

The fuel gauge sending unit is on the side of the electric fuel pump module that drops into the top of the fuel tank .
Not aware of any adjustment .
Questions.

Has the gauge ever worked correctly ?
Is this a new to you coach ?

Sending unit float is on the table in the back of this picture of the pump module.

The fuel gauge works. When filled it reads about 7/8 of a tank. Your pic looks like a standard gm/ford type combo pump. Probable no adjustments their. Dealt with plenty of them. Maybe something can be adjusted at the Instrument cluster. We'll see whom else chimes in.

Ed grey , answers a bunch of questions in the Workhorse forums ; if any member knows about a possible reset or adjustment ; Ed is the member who will know about it.

I have same issue. I’m thinking I’ll try a solid ground to the guage before I dig in the oily panel and access

Food for Thought.

With all the contaminates that grow in stagnant diesel fuel systems and the carbon tracking that rears it head from time to time in gassers in todays vehicles causing irregularities in fuel gage readings, I would first try a quality product that cleans fuel systems and use at least for a min of a couple of tanks of fuel.

Yes they do work if contamination is the underlying issue and it normally takes a few tanks of fuel for them work.

Yes they could make a product that might clean it in a few hours in one shot ..... that said it would probably take out you fuel pump and injectors in the process

Happy Hunting

Update....hope this might help others. Found out my dash guages are part of a workhorse recall. Whom ever performed the replacement procedure might not have gotten all the gauge dials set correctly. Easy fix. Pulled out gauge cluster and removed plastic bezel. Rotated dials in appropriate direction to set them to zero. There is a test function for the gauges if you have the recall manual for the gauges from. Acacia . I think i got that name right. A lot easier than pulling a fuel pump.....All is well. For now...
