I don’t know what happened but I don’t see how DEF was pumped into the underground Diesel tank if they are two different thread sizes. But then I’ve never seen DEF being pumped in a tank. Wish the guy would have got a fuel sample from that pump but that would have been nearly impossible since his truck wasn’t running. The thing I noticed is he ran a hundred miles or so apparently without a problem after changing fuel filters then put 9 or so gallons of fuel in his truck tank and shortly after that started having problems. How did he go a hundred miles without problems and then suddenly develop problems if DPF was in the truck’s tank but on the other hand why did he have problems at the station and haft to have his fuel filters changed.
There is something here I don’t understand and I don’t know what it is. When you get more information please let us know.
