Fuel gage sending unit

[Rfw1955]

I have a 05 beaver Monterrey with a bad fuel gage sending unit. I can see the sending unit on the drivers side on the side of the tank. My question is any info on changing this unit? Thanks

Yes sir! I just completed mine on a 1999 Diplomat. I called Monaco and talked to their parts department. I gave them my VIN and they will cross reference it to my sending unit part number. I ran the MH out of fuel. There is a drain plug on the bottom of the tank. I thought I was pretty close to empty, but ended up draining 28 gallons. Once you're empty, I could access my sending unit via the first compartment door on the front side. Inside the compartment, I had a 4" cover plate that I screwed out. Pull three screws and it will slide right out. Be sure to mark your wire connections before pulling unit. We completed the job in about 1 hour.

Thanks gprince was your unit on the side of the tank , also was your unit a centroid ? Mine looks to to be a round 3" unit with Allen screws holding it into the tank

That's it !! Thanks Rex did you get the unit from Monaco or centroid

[gprince]

Mine was the Centroid fuel sender.

Has to come from Monaco as I don't think Centroid selld direct. You could check with them first about selling direct.

Rfw1955......You say it's bad.....what's it doing. They are adjustable. Mine was reading fine for four years and then acted up. Centroid told me that I probably had algae on it. I knew that wasn't the issue. I readjusted mine and it's been fine for two years.

Diplomat Don here what is going on the Gage reads past full sometimes after sitting the unit works fine now the Gage reads past full all the time.

Rfw,
Just had my fuel gauge fixed. I thought it was the sending unit, but turned out to be a wire shorting on the chassis somewhere.

Rfw1955......I would remove and clean all of the wires on the sending unit and then adjust it. Moving the adjustment screws MAY resolve your issue. Here is how to adjust the unit http://www.centroidproducts.com/moncal.htm

Thanks don for the info by the time I checked into this post it has been pulled now I am looking at the sending unit the damn thing looks clean and new, I wonder if I can bench check this thing?.
