It acts like it’s s#^&#^&#^&#^&#^& air, it is s#^&#^&#^&#^&#^& , one minute a ton of pressure the next air mixed in ,,, WTF
No leak on the pressure side.....

It’s getting the water from the live well pump Y fitting ... the lower outlet?
Attachment 66474

That’s s u c k i n g air

Do you have a value shutting off the route to the livewell pump when you’re using it? I’m not 100%, but it may be that the flow rate of the pump is creating enough pressure at the “y” where you’re sharing the pickup with the livewell pump that it’s pulling from both directions at that junction. Turning off the ability for it to backflow air from the livewell pump may help you at least troubleshoot the new unit.

Ray, remember I had the same boat. I moved mine in the off season so I could get at it with ease.
