This type of nozzle (shown) is very easy to use because it does not have the sleeve over the nozzle. I can insert it into the filler neck and it will stay there without my assistance. I can then put the trigger lock on - let go and relax while I'm filling up the tank.
Question: Why do some service stations have the other kind of nozzles (not shown) that have the rubber sleeve extending the full length of the nozzle to where you have to stand there and hold pressure on the nozzle so it won't fall out? What a PITA!!!
