1984 GMC/Chevy Truck

I need some help, I have two trucks one was an 82 chevy stepside, and the other was an GMC High sierra) that I am going to converted into one, I had strip both of them and pick the best of both of them (body parts, wires, frame, etc. ) to make it into one truck, I decided to use the 82 frame, and the parts of the 84 GMC with ac, i am making some modifications and at the same time trying to keep it some what stock, I had put a mild sbc 350 so I dont want to used any of the stock electric gauges, i am going with the mechanical gauges, i am using an edelbrock 600 or 650cfm, my two questions is, my gas tank has three outlets one for sending, return and evaporator, that is supposed to go to this canister in the radiator, if i was to used this canister (with three outlets) can i connect one to the evap. line from the gas tank , and the second line to the pcv valve outlet from the edelbrock carb. or should i just capp the line and do away from the canister, has anybody done this. second question: my truck will have the ac unit that came from that year(84) i know is r12 but i just want to make it look like it works, i connected all the lines but one, is a black tubbing line that goes out of the firewall and is supposed to be connected to some vacuum tee, can i connected this to any vacuum line coming out of the intake manifold?

Can't help you with A/C because i don't know anything about that and have not run A/C in probably 20 years unless the car i'm currently driving has it working----usually a borrowed car or the car i just bought has it working.

2) i'm curious why you want to run mechanical gauges when you have to wire them for light anyways? Unless you only drive during the daytime? Mechanical are not bad--they may even be more accurate, but in my opinion electric is actually easier to install.

3) i don't know what the emissions laws are like in taxachusetts, but i've simply plugged my canister off since i don't use the stock quadrajet anymore; i have an 83 truck. i've also plugged my return line off with a bolt and hose clamp---i am now using a 78 malibu fuel system--rochester 2G and the 78 2g system did not use a return line.

This works well , but i would like to hear as many opinions on this emissions matter as possible.

a) The black tube coming out of the firewall might be for the torque converter lockup. A picture would be helpful.
