Can anyone tell me the part # to the O-ring

in the burp Bung, mine has a small leak, and I want to replace it. Went to Ford, and they say they have no info.

There's a ring around your bung and it has a leak??? :D
2.5mm X 27mm or a 3mm X 27mm (I think!)

Try a hardware store or FLAPS. Just make sure you get neoprene rings.

Thanks, I thought there was a part#, but Ford says that the threaded plug isn't available anymore either.
