Not sure if anyone out there has had this happen and might know where to start.

I have a 68 arrow with the IO-360 and it's fuel injected (IO).

About 1 month ago I started noticing about a shot of fuel coming out of the induction vent tube after I would shut down the engine.

I never leaks as run and only leaks a small amount after shutdown. I had my mechanic check the fuel cut off and it's fine, we also validated it was not fuel pump leaking.

Our suspect right now is that it's the fuel diverter that sits on top of the engine. I've spoken with two separate A&P's and both agree that it's most likely the pop valve in the diverter that is allowing a small amount to leak into the induction system after I shutdown and during the cut off.

Likely if we rebuild the diverter/distributor of the fuel it goes away but figured I'd at least ask if anyone else had run into this.
