I’m installing new pistons in a 96 ultra for my neighbor. Got the cylinders off and there’s a small brass fitting about 1” long and 1/8” diameter coming up out of the upper part of the crankcase between the mag and center cylinder. There was nothing tied into it but it sure seems like there should be. What is it for and should there be a hose hooked up to it? Have a look at the attached pictures. ![BFAB5392-3A69-4D54-895F-DF618C80028E.jpeg BFAB5392-3A69-4D54-895F-DF618C80028E.jpeg](https://www.snowest.com/forum/data/attachments/310/310240-8c1be43eb5e09636dd1a3b890986a520.jpg?hash=jBvkPrXglj)
