Gasoline smell in R27 OB

[brofish17]

I've occasionally smelled gasoline when entering the cabin, but it dissipates quickly and is never noticeable while we're using the boat. Yesterday I went to the marina and entered the cabin and the gasoline smell was overwhelming. Again, it dissipated quickly, but now I'm really concerned. I opened the center cockpit hatch and the smell is very strong there initially. I closed it for 10 minutes then checked again and the smell returns. There's less than 40 gallons in the tank, which is is rare for me. How do I go about isolating and resolving the issue?

Any indication of gas in the bilge? Check any hose connections for leaks.

Also check the fuel tank vent line.

We had a loose fuel filter on our r27 outboard when it was new. It caused a fuel odor. Check that the fuel filter is tight. Hope that helps.
