diesel flowing through an inch and a half hose would bottle neck when it hit the nozzle itself, so why bother?

Maybe I'll get you back on track. I can't speak to back in the day but from 1999 most truck stops in TN. use bigger nozzle and hose for the semis. I can fill the pickup I spoke about in 1st post in half the time as opposed to using diesel pump at car pumps.
Now you walk around the corner to the car pumps and they are using the same pumps. Can't speak to computers and pumps different in pumps that look just alike. Maybe the pump guys can help with that.
