I've promised myself that I will rig up the "proximity regulator" very shortly for the SD.

It will consist of a small tank of diesel fuel (with some added waste crankcase oil), a pump, and two nozzles that are mounted to the rear bumper.

I'm trying to find a fuel pump that is reasonably cheap. I don't think the wsw pumps will survive the diesel fuel.

A small switch inside the cabin and I'll be all set.
