F.V.S. AKA: fuel vapor separator, that thing with the color stripes. But no matter you call it.
"In theory" give the fuel surge and the vapor that might get in the line separated to send it back to the tank or another Smoggy part. I went from the pump to the carb for years. But I never did cut one in half to see just what makes it tick. Might be interesting.
