How big can the fitting be at the back of the intake manifold and still promote good water flow throughout? Curious as I have dumps from when my boat had blowers on it and would kinda like to hook them back up again

Currently have a mechanical water pressure gauge with hook up at the front of intake manifold... Is that sufficient
most water pressure rigging I've seen and rigged is taken off the engine block, there is a port (1/4" NPT) near the center core plug

I run -6 AN off the back of my intakes to overboard dumps in conjunction with separate intercooler dumps

Chris, I'd just tee the lines together and install a valve to regulate flow. You don't want much flow, too much and you won't build any heat, stat will never open. Whatever size the fittings are would be ok or you could reduce down to 1/4 npt. I'll bet that's what the fitting size is that's there now.

Any pix?

Wasn't going to install there... see below

CP has a 1 1/4 inch slip on union with a 1/2 npt fitting in the center for mounting the press reg valve. This should go in the rubber hose that goes from sea pump outlet to the engine, preferably near the pump itself.
I actually already have that exact one and plan to use it for the relief valve.... going to install it after the oil cooler but before the cross over. That's better than intake manifold no?

In my opinion, yes.
