said by McSummation:There are 2 nozzle sizes for Diesel - "truck" and "auto". "Truck" nozzles are
big and have a high flow rate so they can fill up a 75 gallon tank without waiting all day. "Auto" nozzles are about the same size as unleaded nozzles.
What you may be thinking about were the "leaded" nozzles that are too big to go in an unleaded fuel tank.
Nope, I'm thinking of the regular ol' diesel pumps.
Like imrf and Lurch, I've been all over the country (in a Freightliner Columbia no less) and I've never seen an "Auto Diesel" and "Truck Diesel" variations. Even with the larger nozzles, it still takes 5 - 10 minutes to fill two 100 gallon tanks.
My vote still goes for "trolling".
