Hello I have a 76 corvette and I was looking at the vacuum hose diagram for my smog pump and it on my manual it looks like like there is two hoses that run to it but I’m not exactly sure and if the other hose that looks like it connects to it doesn’t what would it run too? Here’s the diagram This is what I think connects too but I’m not sure This is the only part for a connection for the smog pump That’s the carburetor vacuum port That’s the efe tvs switch that also looks like it goes to the pump
Your confusion is because you're mixing emission system connections. Smog or A.I.R. differs from EFE. See if this 76 photo and schematic help. The engine photo is an L48 M40 and did not come with EFE...only L82 in 76.
