I fix industrial equipment for a living. My relationship with my boss is pretty good and I have free range to the shops equipment on weekends and after hours. This includes a blast cabinet, parts cleaner and ultrasonic cleaner. I also have some connections with a company who does powder coating so I can prep the hardware and then send it to them for a lot less than what's typical.
Still looking for a space to totally strip the truck down but one thing at a time
Get rid of the stock filter up by the engine. Only need one. Put it before the new electric pump. Something like this from Amazon...
