$50 Craigslist 360 EXTREME budget rebuild??

20170422_163013.jpg I could still use ideas on routing the water lines. Mechanical aftermarket pump with a plate on the fins??
I gutted the thermostat and using short bypass hose so would it hurt or help to just make a short heater hose line from the pump to the intake? I just as easy could pop a piece of hose on and paint it.
