Nope it wasn't me. Nice thing about truck stops around here is they do not mix gas & diesel nozzles on the same islands.
On the U-haul running gas. If it has a Ford and run all day, I would consider it down for a 4,000 not 400 repair. Complete fuel system replacement including injectors.
A buddy in Seattle area emailed me about his neighbor topping off the tank on a new PowerStroke with gas. It ran rough, but got him home. Ford dealer came and picked it up and said if the gas ratio was low enough and not run long it would only be a fuel sysem clean-out. If the gas ratio was high enough, then a complete fuel system (including pumps & injectors replacement) was needed.
