A correctly restored gas pump should have the correct nozzle.  The correct nozzle is the one that was on the pump when it arrived at the station from the manufacturer.  Most of my literature on individual pumps identifies the nozzle or nozzles that were available when the dealer ordered the pump.  Just click on the company to look up the correct nozzle.

(Please note, this is something that is under construction, it will take a while to look up everything and get it posted here.  If your pump is not listed, just contact me and I will look it up and get it posted.)
