Review on Enhance Accuracy and Durability with Yellow Jacket 49010 Lexan Crystal for Most 2-1/2" Gauges by Daniel Steele

Why buy a new pressure gauge when all you need is a cup? Please note if your gauges are older than 1985 it will not fit. The old ones have fine threads in both the metal head and the cap. This is for the newer sensor which only has tabs on the body for screwing on the cover. If you're reading this, you most likely have a newer style. I still use) still kick (no cure for those old sensors or me for that matter)
