Kidoo.....The Centroid fuel sending unit has everything incorporated into it, including the fuel pickup. On your coach, you have a panel on both sides of the coach, just behind the front wheels. I'm not sure if the Cayman had dual fuel fills, but the panel where your fuel door is located, actually opens.

On the driver's side panel, look under the coach and you'll see two screws holding some tabs down. Remove the screws and the entire pane with lift up, its hinged at the top and will take a broom handle to hold it open. Once you have it open. you'll see the fuel sending unit, about a 18" in from the edge of the tank, right on top.

Side Note.....I'm my Diplomat, I removed the screws on these two panels that access the tank and added a latch mechanism. There is a lot of valuable storage space atop the fuel tank. I use to keep tire chains and a blue toilet tote in there.

Here is the Centroid link for adjustment.

Thanks,very good info, I will check this out.

It's been years since I made the last adjustment, you may be right, two units near each other Centroid and pick up assembly.

The rest of my Centroid story: With a new 04 rig Monaco the gauge was not accurate and Monaco attempted to calibrate it twice. Before the second failed attempt I knew more than the Monaco factory service center. I knew they would not be successful since they never asked me to fill the tank.

OK maybe they extended the wires and used a bucket of diesel to calibrate the gauge, yeah right. :@

But Monaco fixed over 70 warranty items some of which they found. So good experience for me although it would have been nice for their QC to find the problems first. :)

Any then I could run to AZ to E and add 80 gallons to a 100 gallon tank not that I recommend anyone else try this. With kids in CA I did this often.

Don, Different than my 04 Endeavor which an separate Centroid and separate gen and engine fuel pickups and returns. Guess I'll check the current rig.

Anyone knows where is the pick up tube? Is it sucking fuel up or is it draining it from the bottom of the tank?

We do the same thing....drive from the north end of Los Angeles and get fuel at the Pilot at the Havasu exit. Fuel up there on the way home too.

I don't think I ever pushed my Monaco past 60 gallons, and only on one occasion. 60 gallons was over 500 miles and a full days drive. I know a lot of people pulled the Centroid unit out to replace the generator pick up tube, making it longer. Monaco made it short so people wouldn't run out of fuel, but many feel it should have been up to them to monitor their fuel use. I know mine would quit working between a 1/4 and a 1/2 tank.

Don,

I agree that the Monaco tank design leaves a lot to be desired. If the gauge was in the center it would have a better side to side average but then it would be difficult to access w/o dropping the tank.

My main concern was knowing the tank level so that when leaving CA I could arrive on E into AZ, driving on a known road, normally I10. Fuel in AZ was $0.20+/gal less in AZ.

So my experience was different and I had no issues with the gauge vs the Monaco design.

On my 04 the gen ran out at 3/8 on the tank and the low light was just below 1/4 on the gauge. You may not have a low light, check the rig manual.

My '08 is just like yours.
Bother me sometimes that I can't use the genny unless I have LOTS of fuel.
And no matter how far I pushed her, never put more than 65 or 70 gallons in. DW gets a lil freaky when I push fopr the limits, so much as I want to know, I've no idea how much fuel I really have.

I kinda like Don's way of adjusting for half a tank.
