Running out of fuel before I'm out of fuel...
I have a 2000 F550 with the aft axle tank. To my suprise one day after I got it last summer, my fuel light came on, and about 2 miles down the road I'm out of fuel. Needle is still over empty and all that. Filled the truck up and it only took about 35 gal if I recall correctly. The tank is a 39 gallon tank, so I should have had 4 gallons left. this happened another time, about the same way. well I was comin home last night, truck is just below 1/4, light not on, as I was trying to get as much out as possible because I wanted to address this issue as well as a pinhole leak in the tank. to my surprise I'm almost home and ir runs out.
Now usually I put fuel in, run the key a couple cycles to reprime it, and fire it up. It will run like crap for a few miles then clear up and run great. Last night, I put a 5 gallon can in it and it wouldn't start. It was trying but nothing. so I let it set overnight with the charger on it, still won't start today. Pulled the filter, looks good, but fuel is a little murky in the bowl.
So, does anyone have any ideas on why this could be happening?
Something else that may be a clue is the truck will go 150+ miles when the gauge reads 3/4 tank, but after that the gauge drops like a rock.
