I've been driving my 77 Bronco post EFI conversion for 2 years now w/0 any leaks. The other day I noticed a puddle under my Bronco and to my surprise it was gas. The leak was coming from a a junction in the vent line on the outside of the passenger frame rail. Please see picture. Does anyone know what that thing is called and what it does? Can I just bypass that thing? My vent lines ultimately end at the charcoal filter in the engine compartment. Has anyone had a similar problem/ what should I do?
