I was getting ready to fill the tank with diesel last week, and accidentally picked up the gasoline nozzle briefly, then realized my mistake and traded it for the diesel nozzle about 2 feet away at the same pump station. Yes, they were color coded correctly which is what eventually caught my eye. This got me thinking, what if I actually pumped gasoline into the tank? I know better to try to start it, assuming I've realized my mistake, but what next? Has anyone carried through with this terrible mistake? What happens if you DID start it after pumping gasoline?

Read about it in forums over the years. Easy to do if not paying attention and drive a gasser most of the time. Just the other day, I went to reach for the gas nozzle instead of diesel at the station where I always fill up my car. Luckily I caught myself like you did before I filled up the truck....

Don't know that to be factual...Roy KenThe diesel nozzle is larger than the gasoline nozzle. It helps people from putting diesel into their gas tank. I always thought that diesel color coding was green until I went out west. I think I saw yellow color on the diesel nozzle.I always double check when filling the diesel truck because that is just the kind of thing I would do!

In my experience the diesel pumps in the normal car area have small pumps (may have encountered a couple that had larger nozzles). The truck lanes almost always have large nozzles. Some places have several pumps for RVs. I have encountered both large and small nozzles.I never trust just the nozzle color. I always look at the label on the pump regardless of the pump nozzle color.
