A kink anywhere in the fill/vent tubes will cause a problem.

I bet the vent line has a low spot that is acting like a trap under your sink. It probably evaporated what fuel was sitting in the "trap" last week allowing you to fuel.

Great advice...I have another semi truck companyy looking at it Thursday. I'll make sure they have all the details.

So I understand are you saying insert the fuel fill nozzle and then put a finger of the vent hole? I'll be happy to give it a try.

The "vent line" you are referring to...is that the line that connects to the tiny vent hole near the fuel fill hole? Or the vent that goes to the charcoal filled evap system? Thanks for your suggestions

Make sure that there isn't an obstructon or kink in the vent line to the filler neck, and that NO portion of that vent line is lower than the filler tube. As mentioned above, a low spot in the vent line can allow fuel to accumulate in that low spot, which effectively blocks the venting.

Pull up to the pump, raise the fill side a bit with a block or the leveling jacks and try that.

I bet if you put a straw that fits fairly tight in the vent hole and blow through it that will clear the fuel that has accumulated in the low spot and allow you to fuel. Unless the vent hose is actually kinked. Then you will know because you will not be able to blow through it.

I'm wondering if this was ever resolved.

Nothing bothers me more, to find someone with a similar issue that requests from the knowledge of others... gets loads of info, and never updates the original thread/question with a solution (if found)

I've had to do this since day 1... to get a "full" tank.

Now, my fill surround has broken free of the shroud and I'm having the same problem of the original poster. I too assume it's the vent.

Anyone know where to buy a new 'shroud and fill orifice" for a '99 Winnie Cheiftain?!
