    It really can be Helpful ...... It all depends on what set of shoes you are standing in - to be quite honest.

    I've been working on this problem for a while, and, as far as I can tell, there are multiple possibilities. In this case, the mechanic claims that he has pressure-checked all the vent lines and that that doesn't appear to be the problem. He thinks it's a restriction at the bottom of the fill neck -- namely, the rollover valve.

    From what I just googled, it's a plastic ball that also prevents siphoning gas from the tank. I can't quite figure out what would cause it to malfunction unless it became deformed.

    I have worked on Volvos since 1980 and have never had to replace a roll over valve.

    The "can't fill up car, gas nozzle keeps shutting off" problem has been caused in the past by one of my techs blocking off a vent line under the car to do a smoke test - then forgetting to remove the blockage. Car comes back and after removal of the "test plug" is able to be refilled normally.

    Well, then I guess I'll have to take it to another mechanic. This guy says that he has had one Volvo before that had a problem with this anti-siphon/rollover ball in the fuel inlet.
