Re: Water pressure guage HELP!
There should be a hose coming out of the top center part of the block on the V . If no hose is there a plug screwed in there? Normally that feeds the poppet valve on the lower starboard side of the block. If there is a hose feeding out of the top of the block, then splice in there with a TEE and connect the small hose and run it to the guage. DO NOT FILL the hose with water, it works on air pressure.
Tapping into the pee hole will not give you true pressure reading.
