carburetor question
 

Ok, so I've got a four cylinder F head engine on my old jeep. I'm replacing the carb with a Holley 1908 carb since it is a direct bolt on and has a lower profile. Anyhow, does anyone know what that line is that goes into the carb base? It's basically coming up from the bottom of the pic and going into the top of the intake/bottom of carb. It isn't the fuel line. Help? thx.

Fetzer valve.

Vac line?

no, the vac line is coming out above it and is currently taped off. I've got to reroute that. I just know that i've read all over that this is a direct bolt on app, and the new one doesn't have the port for the whatever the hell it is.

That's what I as thinking. Also with a ?

If I had to guess, I'd say it's your main vacuum supply line.

Oh. You're talking about the line running from the carb down to somewhere.

well shit, that is what I originally was thinking. So, then if that is the case, then it is the main, and the one coming out goes somewhere like the crank case?

Where is it going to?

IF we knew that, it might be easier to figure out?

Its it running to a power brake booster somewhere?

Could be an oil breather or pressure relief line of some sort. Is it going down to the crank case or anywhere else on the block?

I'm taking the carb off tonight, so I'll get better pics.

I'd probably ask these guys.

Hope to hell the thing doesnt come apart in mid air. If it does then we know its the "anti come apart in midair hose"

That’s where I’d go with this question.
