Getting Diesel at service station or truck stop?

Also remember the truck pumps have large nozzles and unless your pick-up has the larger fill tube, you have to hold it tight against the tube and it comes out very fast and will spray the side of your truck. I understand you can get an adapter for the nozzle. Our truck doesn't have the larger fill tube. The biggest problem we have is finding which pump has the diesel at the smaller stations. They should mark them better I believe.
