This is just a picture I pulled from ebay.

Anyway what/where does this little hose connect to? It's missing on my engine. It's off the big hose from the air filter housing.

Probably connects to the diaphram rupture port of the pressure regulator. Here are pics of the hose and the regulator. Is there anything connected to the port at the bellhousing end of the pressure regulator? If a hose is there, is it connected to anything else? If laying unconnected, would it reach the breather hose port?

Thanks sbourg,

I couldn't see the FPR with the air filter housing on. I'll check on it next week while I replace the MAS potentiometer.

Looks like the hose that goes from filter housing to the side of the valve cover.

Thanks for your input, but if you look closely I circled in red the little hose that comes off the big one. Mine is missing the little hose.
