Pneumatics Manual says 'The gauge may be placed ...(on the Norgren regulator)', but what that word 'MAY' means to First this year may be a mystery.
Last year, we were called once for no gauge, but may was taken as permitting, not requiring, and we _were_ allowed to compete. And at the Nats, there was no notice taken of the lack of gauge.
We did have to produce a gauge and temporarily attach it to prove that the pressure downstream from the regulator was proper.
