Look at the intake holes (on the right side facing the camera) on both of these carburetors. Notice their relative positions to the flange where the carburetor connects to the intake manifold. Do you see the difference in distance? That's what I'm referring to. The line has to be longer for the Zenith, and is so different that I can't simply jerry-rig the line to fit the Marvel (ie bend it a little). It's too much of a difference.
