I have the gauge in hand but ain't found time to install. It does have a water line. Ran it some today it actually shows 10psi with engine off. There are scenarios where a guage will not help. But it will show degredation of a water pump. And I am a sucker for data points. I actually went to school with Tutor Meredith. One of the pioneers of low water pickup.

A new guage did the trick. While I was in the engine I noticed the water line and fuel line was a little choked down. After replacing and rerouting I ended it with more water volume and two more mph on top end.

Sounds like some frustration turned into a pretty good exercise with great results. Now you need to get us some fish pic’s.
