As title says 1990 5.8 starts up but then dies i am assuming a vacuum leak as before i purchased the truck it had vacuum lines missing still does. And i want to get the truck running as i plan for it to be my dd for a while.

1. Truck will run if i keep giving it gas.
2. Vacuum tree has a missing hose i dont know what it is.
3. There are no lines on my front driver side canister
4. Yellow line by passenger canister is capped off
5. Cruise control has a missing connector

I have the haynes book for this truck but doesnt show much for helping this section out!
