Ever get that sinking feeling when the engine's rpm starts to fluctuate, eventually killing itself? Hate that feeling...especially when you are about to enter a marina. Yikes! Recently my engine died. Went below deck and loosened the bleeding nut located on the fuel filter (not the primary one, but the one between the fuel pump and the injectors). I bled quite a bit of air, started the engine and it runs just fine. So, now it's a matter of finding where the air is being drawn into the system. First thing I did was checked all the fuel line fittings, make sure they're nice and tight. I found that 2 of the hose fittings were 'snug but not tight'. I put a wrench on it, and without much effort, I managed to put about a 1/2 turn on the nut. Question: How tight should these hose fittings be? Like I said, the nuts were snug, not loose. Would that be enough to cause air to be drawn into the fuel system? Is it possible to over tighten some of the fittings/nuts? James Marohn Perelandra - Vision 32 Seattle Washington
