Hey there,
I bought my 1970 GMC K2500 after seeing it sit for over ten years. I’m currently driving it as a work truck, and trying to get the money together to completely rebuild the engine and do a cab swap on it.
My problem right now, is I have no idea about vacuum lines. Ive read a bunch of the forums on the website, and have done some googling, so I think i know where to start asking questions.
Very first thing. Should i get a charcoal canister? Mine is completely missing
From there, the Thermal Vacuum Switch is totally unhooked.
The crankcase vent filter doesn’t stay attached at all.
I think the PCV valve works.....i think
