Yes, they're a pain in the butt. I've never been able to set the pump nozzle and walk away from it, but with the flip cap the vapor recovery sleeve doesn't usually fit inside the cap. At the station I use the most it sits on the outside of the flip top frame, so the nozzle doesn't go as far into the filler. I don't have to hold the vapor recovery sleeve, but I have to stand there with the nozzle the whole time.
