I used the 18" tube that Geno's sells so that I could attach to the post filter shrader valve. I found that if I tighten the connector to the shrader valve, I don't get a pressure reading, but if I leave the connector kind of loose (only finger tight), I get a reading, but it's not consistant. What's up with that?
It's almost like the shrader valve is closing if it's too tight. Should I remove the shrader valve? Any idea's how to make the reading mre reliable?
