My Tesla modules have 5/16" coolant outlets.
Automotive grade coolant pumps typically have 3/4" inlets/outlets.
Is it ok to hook 5/16" line up to a 3/4" pump?
Seems to me you might have fluid starvation from the smaller feed line.
Thank you.

You should check what Tesla uses for battery module coolant distribution. It would probably be a good idea to use that as a guide, since you are using their modules.

You need multiple modules in parallel in terms of cooling connection.

Bernoulli says the flow rate through the different hose diameters will be the same. Learn the flow rate of your pump using a 12v power source and a couple buckets, then see if your small diameter hose is sufficient

Mr Ohm says resistance results in lower flow for the same pressure.
