I have a 1980 Z28 350 that I'm trying to smog. The smog pump is missing. There are 5 hoses that need a home. 2 come off the exhaust manifolds and a small vacuum line that should go to the pump diverter valve. There is also a half inch line that Ts with the drivers valve cover and under the carb. Also, the air cleaner has a hose coming off the front.
