Fuel tank capacity Monaco Cayman 2003 Diesel
I would like to know how much fuel you put in your fuel tank? The book says 75 gallons. The other day, it was between empty and 1/8 and I added only 53 gallons. So this would be 22 gallons left to use...

Diesel engines stop immediately when then get air so you don't want to run the tank low on fuel. For this reason Monaco sets the gauge to read E when the tank is about 20% full. The generator pickup and low fuel light are above that point.
Monaco uses a large side to side tank and a Centroid fuel gauge. Because of the design of the tank and the fact that the Centroids are not very accurate, your fuel gauge will be way off. The Centroid fuel gauge sending unit is adjustable, but takes some work to get it relatively accurate.
The Centroids I've had are very accurate, repeatable and stable. The design is 2 concentric tubes and when the fuel reaches the bottom of the tube that is E on the gauge. The tube length is cut to length so that the gauge reads E when there is about 20% of fuel remaining in the tank.
The Centroid can be calibrated. Fill the tank then pull the gauge out and set empty. At that point you can measure it's length and measure the tank to determine how much fuel is left when the gauge reads E. Reinsert the gauge and adjust for F. I did this at a truck stop and my 04 Endeavor Centroid was cut to read E with 18% fuel left in the tank.
Best to add fuel before the low fuel light comes on as the generator pickup will be above the fuel level.
