There is a big, fat hose that sorta lays on the HE and connects to the outlet. On the other end, a smaller hose rises up thru the engine tin to the pump itself for the thermostat. It's the only air hose that has anything to do with the MFI on mine. There is also a hose from over under the oil filter to the snorkel tip for warm air idle. I've never seen one hooked up. '72-73 had another device for the induction air. I don't know about that.
