Currently exploring that option, but having the fan belt drive a pulley.How much room is there above the starter, in front of the alternator? Pics look like the pump might squeeze in there driven by a longer shaft, you get the idea.
Like a serpentine belt on a car, the pulley would be driven off the back aide of the belt.
I really want the pump as low as possible so the pump inlet is “flooded” rather than trying to draw from a tank mount lower than the pump.
But JD isn’t making this easy, every square mm seems to be crammed with something…
