I have a 2001 115 Johnson on a 17 Venom. The power head has been rebuilt and I’m currently breaking in the motor I have about 2 hours left to complete the process. I took the boat out Thursday and my no oil alarm came on soon as I back boat off the trailer, I idled over the the side and checked lines and oil tank and everything looked good. Started it back up and no oil alarm came back on for a minute and then went off. I went ahead and took the boat out and started and stopped several time no other issues. Today I decided to look at the engine to if anything was out of place and found the attached hose not connect Ed to anything. It is connected to a T on the the other end then is commcected to what looks a vacuum pump between the carbs. I can’t find a place that looks like it would hook up to. Any help would be appreciated
