Alright, gotta' tell this one from last summer... . long winded but illustrates that some people should simply not own a Diesel anything!!!!!
To set the stage you need to know that most of the Irving Gas Stations in Maine have a dual pump on the outermost car island that has Diesel (with Green handle) on the left and the three grades of gas (with yellow or black handle) on the right.
It is very handy for Diesel cars and pick-ups as it is a small nozzle plus you are not in the way of the big trucks over at the dual nozzle lanes.
I am waiting my turn for the pump and in front of me is a 3/4 ton Dodge gassing up. I notice that he is putting gasoline in and think to myself it must be a gas sucking pig if it is a Hemi, all I can see is the tailgate at this point.
Then I see him frigging with the pump, sliding his card in it, etc. . Finally he heads inside. I know what has happened, he has hit the $80. 00 limit and has to restart everything.
I see a hole open up on the other side and back in. Look over at his truck, see a Cummins emblem on the fender, gasoline nozzle is still hanging out of the filler door and figured I had better speak up... . His wife is sitting in the truck, I stick my head in the window and ask her if the truck is indeed a Diesel, she replies that it is so I proceed to inform her that Hubby has just pumped it full of gas. She is no dummy and proceeds to call him a few choice names in his absence.
I can see that she has a clue so I tell her to yank the keys, DO NOT START IT!
I tell her I will stick around to pull the truck away from the pumps if needed until a tow can be arranged.
Hubby comes back out and she proceeds to tell him what he has done. I show him the pumps to help explain and he still isn't getting it. he has owned the truck since new, 2006 just like mine, and proceeds to tell me how many injectors it has destroyed in 60,000 miles.
I'm thinking I can see why... ... ... ... ... :-laf:-laf:-laf
Send for a tow, they arrive and want to start it. As luck would have it I know the mechanic that showed up, told him to not start the truck under any circumstances until all of the gas was pumped out and explain to him that it is not like an old 855 or something. he understands and promises to get all the gas out that he can.
Then they are all wondering how to get new fuel back in it as they do not have Diesel at his shop.
I look at the doomed Dodge and ask the befuddled owner what the tank is on the back of the truck?? He tells me it is a Transfer Flow tank.
I say "Why don't you fill the Transfer Tank with fuel while you are still here at the pump and then open the valve to refuel yourself at the shop after the pick-up tank is pumped out????
Well, you would think I had just invented the Microwave Oven or something!!!
Everyone thought that was a great plan, so the owner steps up to the pump, I turn away to help the tow truck hook on, turn back and guess what he was pumping into the Transfer Flow Tank????
GASOLINE

I flipped out at that point and told him if he touched the pump again I would break his arm off and stick it somewhere unpleasant!!!
I was getting tired of the good samaritan thing by now because he just didn't get it and I had invested a good hour of my vacation time already trying to save his truck. I had his wife fill the transfer tank with Diesel and got away from the whole fracas.
Some people simply can't be helped, good thing I had taken a liking to the wife and wanted to see her get home to her grandkids before the day was over. Him, well he could walk as far as I was concerned after that last stunt.
