wow, are you serious? that's quite a determination you've made. i don't know that i've ever seen anything quite like that on a vehicle before...
it must be a jeep thing that you wouldnt understand
 
I wouldn't worry about the cannister either. I never had to worry about my CJ and it was an 84. I'd take off all the emissions I could. With less emission devises comes less headaches. Some of the older jeeps emissions were questionable at best anyways.
 
Kidding aside. It has probably been many years since that canister has worked. It is not needed for your purposes.

Even if you were bound and determined to hook it all back up, it would be FAR more work than it is worth for no gain.

The existing system. Tank, pump, filter & carb, is all the fuel system you need for that 1974 CJ.

K.I.S.S.

Something you probably should do while you have the body off though, is replace all the lines from the tank to the carb. No doubt there is rust in the steel and dry rotted rubber hoses.

AND GET RID OF THAT STOOPID A$$ glass bling bling fuel filter.

Put a metal inline filter in it.
Like a WIX 33032
or
WIX 33033

Depending on if your lines are 5/16" or 3/8".
 
That hose in the filter picture is cracked and I would guess fairly brittle. If you have it down to hte frame, why chance it adn half ass it? Plus I would run a hardline the full length of the frame rail run.

Yeppers.

You only need a little rubber line at the connection points. To allow some movement between the various parts. About 6" - 1 foot each between the tank and the hard line. And from the hard line to the fuel pump. Then you will have about a 4" piece between the hard line out of the fuel pump and the filter. Another short piece out of the filter to some more hard line to the carb.

Mind your routing of the steel line - keep it up away from harm from trail trash and rocks.
And avoid sharp bends and body mount areas.
 
Ok I've picked and insulted enough I'm actually going to try and be helpful now.

1)Like everyone has said system will work fine without charcoal canister, set-up.
2) Ditch the glass fuel filter, lots of problems there (broken glass->fire, el cheapo screen filter element not effective, same filter elemet actually coming apart and doing nasty things to carb jet.... trust me ditch it) simple metal fuel filters are great.
3) You definitely want hard line from tank all the way to front, for numerous reasons. (snags,heat,leaks,etc)
4) If its a jeep, and it is, there is a very good chance the tank is either 1) full of rust and soon to be leaking or 2) already leaking or 3) previosly leaking and shodily repaired JUST AN FYI be careful there rust (or GOD HELP ME J.B. WELD) can do many bad things to a fuel system and a motor... if it has sat at all these problems are compounded at a MINIMUM flush the tank well before use.


one side note (from experience that can be difficult to diagnose) an all rubber line set up can actually expand or lose rigidity at higher temps and lead to a drop in fuel pressure that will cause all kinds of weird problems that mysteriously go away once cool... same thing goes for using cheap vacuum hose for fuel line..
Not that I'd ever havee been dumb enough to try that of course, its just what I've heard... errrr... I mean read about in a magazine.. YEAH,YEAH thats it read in a magazine!

Everyone is young, dumb, and full (everyonee can complete this without me writing it) at some point ;)
