    This is an easy fix.

    Our Volvo did the same thing. What is happening is the float is getting stuck on filler cap hanger... basically at the bottom of the chain there is a flattened looking V with a little coil in the middle connecting the chain to the cap keeping the cap with the tank. This flatten V looking thing hangs up the float giving you the false reading. Remove the flattened V piece and it will fix you problem. Just get a long needle nose and angle it out and remove her and you are done.

    Now, the only other thing you have to figure out is what tank has the float. If I remember correctly it is the driver's side at least that is how ours was set up. There is only one flat and you'll see the wires coming out of the top of the tank.

    The only thing is you have have to remember to put the cap back on or she is a goner.

    Hope this helps.

    I always wondered why one of the fuel tanks was missing the chain and V. I may just have learned something today lol.

    I am glad I could help.

    I just wish I knew what technical name was for it.

    This is not a big deal. The gauge has been acting up over 4 for months now. The only reason why am concerned is coz a mechanic told me that with these volvo when the gauge goes to empty the ecm might interpret it as no fuel in the tanks and thus shut down the engine so you dont have to bleed it when you put diesel in. I always reset my trip odometer when i fuel and monitor how much i use.

    If you cant help me with advice i could use then keep you smart comments to yourself. This truck is under warranty. Volvo will fix it whether its something small as a faulty fuel gauge or a new engine. Thanks turn 3

    You are welcome... I hope it is an easy fix and I would personally check easy stuff first before tearing everything down. Also if I remember correctly don't the gauges do a full swing on start up and I think there is a gauge check from the driver computer. It may be password protected. Just scroll through the menus and it is there somewhere.

    One other thing.... the new fuel is wreaking havoc on some diesel components and seals. My GMC Duramax fuel gauge is off around 1/4 of tank.

    Keep us posted.

    This morning i checked the tanks as you had said turn 3. Mine has an anti siphon device already installed. The chain that`s attached to the fuel cap does not even go into the tank. This is on both tanks. I payed a lot of money for this truck and i feel that everything should work properly regardless of how minor it is.

    It was worth a shot and sounded just like the problem I had.

    I agree.... thing need to work the way they are intended to! We currently have a person problem with a "toy", again... I agree things need to work!

    Best of luck and keep us posted on the findings.

    I have to agree with you on this. There is no earthly reason why your truck should NOT be in working order. That being said, carrying a means to stick the tank is still a very good idea. It can make the difference between paying a premium for fuel that you could wait a bit for, and paying a reasonable price.

    Did that make any sense to anybody?????:biggrin_2552:
