2022 Ford Transit 3500
So, this is interesting:
I vaguely remember reading somewhere that the NCV3 does not actually read the fuel level in the tank except during refills, relying on dead-reckoning from ECU information to compute remaining fuel while driving. I can now attest that this information is correct.
For the past few weeks, I have left my Espar coach heater running in our driveway, as an experiment. I occasionally turned on the key to check the fuel level, which started at 2/3. At first I was impressed at how little fuel the Espar was using--I couldn't even see the difference. Eventually, I started to get suspicious. This morning, I got a "lost flame" code from the Espar. Hmmm. Looked at the diesel feed line and it was full of bubbles. The fuel gauge was still showing 2/3. Well, well...
So, I drove to the gas station and filled 'er up, watching the needle as I did. After a few gallons, it suddenly jumped from 2/3 down to 1/4, and then started tracking the fill-up normally. I never did get a "low fuel" warning, even though I usually get it at 1/4 tank. The pump clicked off at 22.4 gal. So, there were 4 gallons left in the tank!
From this, I conclude two things:
1) The sprinter is oblivious to any fuel consumed through the aux tap; and
2) The aux tap (at least mine) goes a lot lower than the 1/4 tank that I was led to believe.
Worth keeping in mind if you are camping in the boonies.
