Fuel Gauge

Has anyone else had any issues with their Fuel Gauge on their 2008 F250 6.4? My gauge indicates it's almost empty when in fact it's still got 10 gallons left in the tank.

Anyone know if there's an adjustment that can be made to make the gauge more accurate?

Jim

My faith in Ford fuel gauges is low right now. 2 trucks were the low fuel light comes on with about 3 miles of range and another truck that reads 1/4 of a tank when empty.

Tank holds 30 gallons... I put 20 gallons in it... 30-20=10.

In case one might think it's an isolated instance at one station/pump, nope.

I've learned that when mine hits E, by the warning message, I still have more than 4 gallons in reserve - it takes about 25.5 to fill it up at that point.

When mine gets to the warning I've probably got that much left too... I'm just not used to less than 1/8 tank on the gauge meaning that I have 1/3 of a tank remaining. It seems to me that they could do a better job on the gauge. It kinda makes me not trust the gauge and I'm probably more likely to run out of fuel than if it was accurate.

Mine's supposed to hold 38 gallons.
When it says 0 miles to E and empty on the gauge it will hold about 33 plus gallons without topping it off. I think that means I have 4 or 5 gallons left.

It does seem to be very accurate other than the bottom of the tank. I can't say I miss the other 5 gallons very much. Probably because I'm used to a 32 gallon tank. If it were ten gallons off then I would consider it a problem. Maybe worth bringing it in.

One thing is, when I'm on a long trip I don't worry about fueling up if I have 1/4 tank on this truck. I go to E.

Mine holds 30.5 supposidly. I normally fill up at 1/8-1/4 tank. When I do that, I put 18-20 gallons in it indicating I've got 10 or so left. I'm just saying that with this expensive of a truck, when it indicates 1/8 tank I'd expect it to have 4 gallons left NOT the 10 I'm experiencing.

The only time this is a problem is when I'm towing out in the boonies and fuel stations are few and far between. When the next station is 30 miles away and I'm sitting on 1/8 tank I can't help to worry even when deep down I know I've got another 8-10 gallons.

FYI I love the truck otherwise.

Now it sort of seems like your at about 4 to 5 gallons on E. That seems to be the same as others have said.

My theory is that this extra fuel is intentional so that you don't run it too low and get the fuel hot or possibly foam from the returning fuel causing air in the fuel system. Could be that there is a large volume of return fuel on this system.

Once I decided that's what was happening is when I started to go right down to E on a trip as if it were 1/4.

It would be nice if there was some official statement about the actual intent of the extra fuel and how much there actually is.

Exactly...

Apparently I'm not the only one experiencing this so I've just got to realize that "E" is not really empty, it means that I've got another 50 miles left. I'm just mentally having trouble with that concept.

I've got to realize that like with computers, it's a feature, not a bug.
