AGGGHHH! Bail out!
Okay, actually, ... How much did you put in? Diesel is harder to ignite so you can expect misfires, it burns much hotter than gasoline which could melt aluminum pistons, but it also has lubricating properties that are not found in gas. Diesel fuel can be used to free rusted pistons and rings in engines that have seized up from being in storage a long time but that's a different issue. The point is it's unlikely anything will get damaged, but you'll want to get as much of it out as possible. If you just put in a few gallons, and it still runs, dilute it with lots of gas and run the whole tank out. If you filled it with diesel, I would pump it out but I can't think of what to pump it into.
Diesel fuel is sprayed in under around 2000 pounds of pressure because it's going right into the cylinder instead of the intake manifold, but it also needs high pressure to vaporize properly. Gas systems only run a maximum of around 55 psi. I don't know how that will affect the diesel but there is going to have to be enough gas entering also to form a combustible mixture.
Being the cheapskate I am, I would try to run the truck's fuel pump and use the fuel pressure test port to pump the fuel into gas cans, then try to use it in one of my pieces of construction equipment. By using half a gallon of your concoction along with ten gallons of fresh diesel fuel, I doubt there would be a noticeable problem.
