Agreed on the bench testing.
Kinsler, RC and others do this, but are very pricey. All you need is a good, stable DC voltage supply (ie a battery with a charger on it), your PWM circuit, a pressure regulator and some instrumentation. As far as flow measurement goes, you can do a known quantity (like a gallon) over time to get the flowrate, or invest in a little turbine meter.
For the pump it's $60 at RC

...and while that's certainly the best way, I'm probably not going to to it and will just rough something in because once I add a regulator it's just a heat management issue and I've already ran this pump with no PWM on the last 2 engine with no issues.
Good is running and fun but perfect is never finished
