I wonder how much pressure your system will maintain, and still be quicker than 85 seconds.

To test at 9psi, turn the regulator up to about 11 or more, then you can see if it’s still better than 85 seconds with the valve adjusted to 9psi.

As long as it’s better than about 85 seconds per gallon, you’d be pretty sure the pressure(9lbs) is being maintained for the full pass.

You’re running jet extensions and a notched rear float right?
