I was wondering what are the standard Vacuum Hose Sizes for an 1982 El Camino with a 229?

I have all the EGR, EFE and TVS Valves intack. I'm waiting on a few more parts like Vacuum Purge Canistar and some other parts.

All the EGR connections seem to take the same size hose?? And the EFE Valve has some large connections.

Hi Philv32, on Purge canister I used a hose from an external oil cooler.. Size like 7/16" ?, 1/2 ". Hope this helps !
