I own a 2004 Truimph 191 FS that I bought 2 years ago w/o a motor. I put on an older OMC 110 and noticed that the engine would not run off the onboard fueltank. Runs fine off portable tank. Inspection found broken fuel line connections at top of onboard tank. There were three connects and only two hoses. One primairy, one reserve, one not connected to anything. Cleaned tank, replaced connections and fuel lines but engine will not pull fuel from tank. Any advice?
