My truck was purchased with the emission vacuum hoses disconnected and plugged. The diagram on the air cleaner is damaged. I shows HKS. The truck is a 1985 Chevy K20 with the HD LT9/350M motor. I want to hook up the hoses but need a good diagram. The Factory Service manual tells me to look at the sticker. Any help would be appreciated.

I found that same one on AutoZone but it is not quite right. My carb has a plug on it on the backside and this diagram does not show that hose. BTW. It is a Manual Trans truck with the Heavy Duty Emissions. Thank you for trying.
