Hello to all,

For the life of me I can not find my factory service manual. I need to see if anyone post the schematic of the vacuum hose routing for the EMISSIONS CHARCOAL CANISTER, DISTRIBUTOR, EGR and EFE

I have got about 90% figured out but I am having a 'brain fart' when the distributor vacuum is being attached. I know GM connected this distributor vacuum hose to one of the TVS ( temperature vacuum switched) in the cooling system on some years...but I think they did that for the 1980-1981 Corvettes...but I can not remember if a 1978 is being spliced into one the the two TVS's.

Thanks for any help.

Hey Dub,
All my diagrams show the dist vac going to port vac on carb. Single hose, not related to TVS's.
