Check valves and vibration
« on: June 03, 2015, 09:11:45 AM »
Spud,
 What are your thoughts about isolating your check valves from engine vibration. Is it necessary?

 An idle or main check valve is open all the time anyway. A pump saver is set so high (130+) that it isn't going to open from vibration. A Secondary is ineffectual at wide open throttle. The only one I might worry about is a high-speed lean out set under 60 PSI. I think a vibration problem is pretty rare, but I have heard of them.
