> When I'm filling up our pickup, it takes a good bit of time -- the pump rarely runs at full speed or the vapor pressure sensor trips, the tank is pretty big, and there's usually a few cars in line in front of me. 15-20 minutes is a lot closer to realistic. I'm willing to believe that it takes 15-20 minutes to fill your pickup, but that's a far outlier. If I was guessing, I'd say that your tank is a factor larger than most cars, and I'd also say that I can't remember the vapor pressure sensor malfunctioning like that and that's also skewing your data.
