fuel gage misreading fuel level

[Travisn1]

well, here goes...
bought an 04 f350 crew psd with 94,000 miles july 1, 07.
since purchase have had it diagnosed at 2 different ford dealers for issues.
it will run like crap under 1/4 tank of fuel, it gets hard to start, etc. after about 1/8 tank of fuel the truck wil start to shudder and loose power while driving, if you don;t get fuel right then, you better be prepared to walk. i'ts left me walking twice now.
ford dealer number one diagnosed an egr issue and possible injector issue, but wanted 100 bucks to go further to cover the diesel warentee deductible.
ford dealer number 2 said it is low fuel pressure caused by the fuel pickup sucking in air. they said they think my sending unit is reading off by about 1/8 of a tank and they can;t tell me for sure until they drop the tank and they wanted 750 for the parts and labor to replace the sending unit. they said it is not covered under the diesel coverage.
thats just the start of my headaches with this truck...i purchased it from a chevy dealer and so far i have been told that collectivly between the estimates for all repairs from both ford dealers that it needs about 3,250 worth of repairs. the chevy dealer agreed to fix 1,100 worth and said thats all they could find wrong.

anyway has anyone else had issues with a fuel sender being incorrect like mine is?

Hey Travis where in Michigan are located. Maybe we can meet up drop the tank and take a look at the inside of it. If the sending unit is off. What is the cost of a new one and installing it yourself.

My gauge was inaccurate needed a sending unit. Ford has a tsb that if you use some chevron techron additive it MAY fix the gauge inaccuracy. It kind of sounds like your tank is pretty dirty. Dropping the tank is easy and so is replacing the sending unit. If you and Bigcountry can get togethor that would probly be your best bet.

the sending units are outrageous. I just priced one for my 7.3 yesterday. they want 500 bucks for the whole assembly

Mine has been doing this for a year or so now. Before the tank goes below 1/4, I just stop and put fuel in. When I top off, the gauge goes above full. I know the sending unit is causing the problem (either bad, going out, or dirty), but this is a minor problem since I try not to let the tank that low in any truck/car I own.

i am on my second Ford truck, both having 2 tanks.

I WILL NOT TRUST THE FORD FUEL GAUGE TO SAVE MY LIFE.

I don't go below a 1/4 or go beyond 200 miles per tank bcuz that gauge is not accurate. i either switch tanks or go fill up. all too often, i fill at 250 - 300 miles bcuz it's sssooo unreliable.

How large is your tank? At 1/4, I'm usually at 325ish if I am pulling and 375 miles empty.

i think my total capacity between both tanks is about 35 gallons or whatever that stock amount is for a 96er with a Long bed. i ultimately don't know how much is left cuz i don't know what the size is of each tank.

Before i got my 05 i had a 99 psd an my truck was doing that an we had the tank replaced an it still did it but then we took it to another dealer an they replaced a fuse an it worked fine after that. So that could be your problem
