My rv propane regulator cover broke (white plastic) while I was cleaning the PUP for a trip. Replacement cost online is less than $3, but is it necessary to replace now or can it wait a week?
Put a baggie over it...just so the vents (small pin hole on 1st stage/larger-screen one on 2nd stage) are protected from elements (dirt/debris etc.). Vents need to be free and clear so diaphragms can move.
