A couple weeks ago I was on St Clair and had my reserve oil tank start leaking all over the place and a Merc dealer got me in right away and replaced it (Thankfully). However, I noticed that the day they fixed it, my pressure gauge stopped working. Water was pouring out of the cowling so I knew it had been disconnected. I pulled the cowling off and found the grey tube dangling, but I have searched high and low and can't figure out where to connect it back. Optimax 250 pro XS 2018. Serial number in the signature. Need some help. :)
