Just got a used 2006 Ford diesel 350. My gas gauge looks like it only shows 1/2 of what's in the tank when it's below 1/4.
Is there a switch to show how much is in the tank or does it need to be recalibrated?
Do you have the 46-gallon Transfer Flow replacement tank installed?
If your van has the 46-gallon tank rather than the stock 37-gallon Ford tank, then your gas gauge will most likely behave in one of these two ways after fill-up:
- Gauge reads "Full" for about the first 10 gallons,
then moves down to "Empty" when the tank is really empty. (This is what my tank does.)
- Gauge immediately starts going down, but starts reading "Empty" when you still have about 10 gallons left.
I do not believe there is a way to recalibrate the fuel gauge.
- Guage reads "Full" for about the first 10 gallons,
then moves down to "Empty" when the tank is really empty.
Some of us also have trouble getting this last 10 gallons in too due to foaming shutting off the nozzle, makes it look like a 38 gal or that you have the 10 on the bottom when you don't.
I wonder if any of the additives we're supposed to be using with the ULSL diesel would help with the foaming. I know there are things some of the refiners add that help with that.
