So going to throw a bus heater in the ol 23 Hourston sbc 350. Heater under rear table seat. A couple questions
.. I have a couple 3/4 ball valves to shut off supply and return and have 5/8 barb fittings in the water pump and manifold.. Problem.. I can't find a reducer to fit the 3/4 shut offs and 5/8 hose. And even if I did. That's I a lot of potential leaks with all the extra fittings . Which brings up the point that. Correct me if I am wrong. That the water pump and manifold have to be looped. And not closed off. Maybe shutting them off temporary is ok ?
Part 2
To get the heated air out of the rear seat box I want to use 3 inch pvc plumbing pipe. Might even have a run of it going into V berth and up to dash nicely hidden for defrost..
The short of it...
...Pvc can handle the heat?
...How to make heater hose with as few connections as possable.
Long post I know.
Mid to high end diesel heaters are not in the budget.
