Factory installed wrong size full tank

For the last several months, I have been going at it with the dealer and factory over this issue.

My tank is supposed to be a 31 gallon tank, but based on total mileage per tank and the number of gallons it takes on fill-up, it is obvious that the tank is a 25 gallon tank.

When I purposely have run it "dry" several times, it will only take 24.5 gallons. I show them the receipts and they act like I am trying to act like that isn't proof of anything!

They have tried to give me every excuse imaginable but won't admit the mistake. Next week, they are taking the tank off the truck and taking it to a gas station to see how much it holds. DUH!

WITHOUT NAMING YOUR BRAND, have any of you had a similar problem?

If so, how was it resolved to your satisfaction?

Thanks in advance!

    1500.....5'7"/6'4" box......26 gallon tank-----------8' box.....32 gallon tank
    2500.....6'4" box...........31 gallon tank-----------8' box.....32 gallon tank
    3500.....6'4" box...........31 gallon tank-----------8' box.....32 gallon tank

    So which 2015 RAM do you have?
    Sounds like a 2500 that got a 1500 short box tank
  • My clipper has two 30 gallon tanks. Both fill to 26 gallons - the remaining 4 gallons of space is for expansion.
  • My short-bed pickup has a 34 or 36 gallon tank and I have filled it up and taken over 32 gallons when the little orange light comes on on the dash telling me I am close to being empty. My first short-bed had a 26 or 28 gallon tank. Both trucks were and are diesels.
  • If it's a GM it's normal. I think my 08 GMC is supposed to be 34 gal. I've never gotten more than a bit over 27gal in it. That was long after the gauge read empty and the puter screaming EMPTY. Normally at empty it's 24-25 gal. An I have no reason to think it doesn't hold what they claim.

  • Brand new '01 Dodge was supposed to have the limited slip 3.55 axle, and said so on the window sticker. It was an open diff. We were always suspect since it didn't work worth a darn. Fluid change time came around and our suspicion proved true.
    It wasn't worth the fight for the cost of the 'upgrade'.
  • All dealerships answer to a Manufacturers Customer Service Representative for the region. The dealer, if you ask has to give you the name and number for this representative.

    My truck had a power steering issue that the dealer was unable to resolve. They called the rep and he arranged for the power steering unit to be sent to Bosch. Bosch was unable to solve the problem. The same problem happened with every unit they tried. It's basically a noise that sounds like you are out of fluid. It's not loud and I have a written document for a free replacement if the unit goes bad while I have the truck.
  • "WITHOUT NAMING YOUR BRAND, have any of you had a similar problem?"

    Nope, suggest you get the factory run sheet for you rig. Should be easy to sort out.
  • Suppose to be 31 gallons according to who?
    If your looking at a brochure, be sure to read the fine print before making too much stink.
    25 gallon take is pretty typical for a short bed truck. 30+ is typical for a long bed. So which do you have?
