I have a 99 Mercury 200 EFI 0G803451 on my 99 Ranger. The last owner told me that the water line going to the gauge split. He capped it and a didn't worry about it. I would like to get this hooked back up. It looks like I should be able to splice the line and connect it back to the gauge. It is a black water line. I believe it is 1/8". What kind of connection is the back of the gauge (Compression or standard pipe thread? Thanks for any help
