Can anyone help me identify this part? I pulled my carbs and VRO for cleaning. While I was in the engine I pulled my High Jet Lines(?)(the very thin ones) off to run a thin wire down them for any obstructions. I accidentally broke the tiny plastic nozzle(not on the carb side...on the other side) The line goes from the carbs to a small black cylinder about 1 1/2 in. in diameter and 3 in. long that has a red plastic turn tab on it. When this tab is turned one way it seems to release the pressure in the fuel system?? I need to replace this cylinder because I can no longer attach my high jet line to it. Anybody know what I'm talking about and perhaps what this part is called? Any help would be great as my engine is ready to go except for this one small part! -THANKS!
