Name of this part?

Recommended Posts

My buddy usually does the work on my car, but we can't figure out the name of this part to get a new one. Pretty sure the previous owner just used glue to re-glue it, wonder if I could do the same thing. If anyone knows the part name I would really appreciate it. The green part. I know it has to do with the gaseous form of the gas, but that's it.

Well my guess would be it is a Schrader valve. They are used on both pressurized fuel and air conditioning lines. The simplest Schrader valve is a bicycle tire valve. It allows air in or out once the center pin is depressed.

I associate the green color with a service/test port for the EVAP system, which as I understand it, aims to hold 1 psi pressure above the gas in the tank to restrict evaporation. So a well glued repair should be able to stand that kind of pressure. Maybe it wouldn't be an easy part to find a replacement for.
