water pressure gauge

[Ray 2000]

do you need to winterize the water pressure gauge?<br />i plan on replacing gauge because needle is pegged all the way over on high side.<br />when installing new line should it be filled with water or antifreeze?

Re: water pressure gauge

The tube is generally filled with air.<br />Water in the engine pushes on the air in the tube, which activates the guage.<br /><br />If you are concerned about water/freeze damage in the guage, just disconnect the guage end and blow some air thru the tube to expell the water. Don't forget to re-attach, or you will pump water into the boat the next time you start it.

Re: water pressure gauge

Thanks a bunch!!!!!!<br />I pulled it apart today and it had some water in it, I drained it.<br />I think I will need to replace gauge, the needle is stuck all the way to the high side. Any ideas?
