Possible fuel excess?

[ndutton]

When working properly air goes IN and nothing comes out. I don't have a Groco loop but I'm certain the cap unscrews to access the valve. I'd be surprised if Groco didn't have replacements.

Sorry to sidebar here - If you are replacing bits n bobs, I would also replace the fuel filter (after the fuel pump) with one that cannot melt in case of a fire. Those are not meant for below decks.
