Those vapor recovery nozzles suck. They've pretty much done away with them in CT. At least the older style with the boot. I will say though that when the tank gets filled fast it will spray out quickly. You can try to pull the boot back but be careful because the idiots that filled their car before you probably tried squeezing in more at the end of their fill up and those boots will fill with gas. When you hold the boot back that gas may spill out onto the tank. Just saying. I lil trick you can do to clear out any gas in the boot is, BEFORE you turn the pump on, stretch the hose out and down the pull the boot back and squeeze the handle. Any gas trapped in the system should come out. Only problem is you'll have gas on the ground which the gas station frowns upon
