Fuel and emission line routing, service manual

[General23cmp]

Does anyone have the photos from the service manual that show a 71 Blazer’s fuel and vapor line routing around the gas tank and also ones that show what it does when it goes to the engine bay (charcoal canister, etc)? I have the normal big red service manual that many have, which is mostly for trucks with some Blazers and Suburban stuff, but I’d don’t see this in it.

Side question: what is inside the tube next to the fill tube where the three vapor lines go in the bottom?
