There are two tanks and each has a sender. Have you tried selecting the aux tank and seeing if the gauge changes?

After my shakedown cruise last week, -I'm guessing about 250 miles or so round trip, the gas gauge showed just under 1/2 tank.

I'd filled it to the brim before I left, BTW.

I've been back about a week and put about 2 or 3 hours on the Onan so I could run the fridge and keep the house battery up. Well today I had the genny
running and after about 10 mins it coughed a bit then quit. Wouldn't start again, tried to run for a second or so then died again.
Even though the coach was level and the gas gauge still showed just under 1/2, symptom was "out of gas" in my mind. Headed over to the gas station and
put $100 bucks worth in. Up here in BC, gas is $1.66/litre which translates to $6.28/us gallon and $100 gets you 59.3 litres or just shy of 15
gallons. [yep I know it's fupped up, but what can ya do]

Anyway, was surprised to see gas gauge stay at just under 1/2. Onan fired up no problem and ran steady after the fill-up.

So ....looks like the gas gauge isn't working properly? I was, as the title says, "messing about in the dash yesterday" -however if it was down enough
to make Onan quit it certainly wasn't at half a tank. The gauge might have stuck when I got back, before I took the dash apart, because it didn't
really change from just under 1/2 all week.

The gas gauge always showed the amount of gas even when ign was off which I also found odd, the other two indicators, temp and oil pressure zero out
when the engine quits, but not the gas gauge  ...normal behaviour?

Have you replaced all your fuel lines.
Some left the gen line alone and it will draw in air and no fuel when
level loweres a little.

The gauge did rise a bit past 1/2 when I switched to the Aux tank  ..I guess what I learned from this is that the gauge works and a hundred bucks
worth of gas in Canada ain't enough to push the gauge up a notch. Basically, money doesn't buy much anymore! :roll:

How big are the fuel tanks anyway?

Larry,
I actually did the test with my 4.0 BF.
0.28/hr at no load
0.52/hr running 1 A/C unit.
There is no reason a 6.0 NH would be much different.
