Update:Spring with no spacer and fresh dot=leak at all pressures.
Spring with spacer (Same Dot)=200 PSI leak still.If I move the pilot with an allen key the leak seals at higher pressures .I tried turning the pressure up and holding it for 5+ minutes but no luck .
Spring with 2 spacers(different Dot)+(Metal Washer)+Original Spacer=Same Issue.
Can anyone confirm Century Spring Part II-21 is the correct spring for the pilot?
I have a Bin 5 noid FYI.
The bands on your case indicate this as well as the # on the noid.
Both mine match up so its not a mix and match.
Installed 2 pilot springs ,same pressure ,same issue.
