I want to get rid of all the smog crap on my FJ40. It's a 1973 with the stock motor. Texas doesn't require I have it on there since I am registering the vehicle as antique. I have been running it with no belt on the smog pump and that seems fine. What do i need to do to get rid of all of it? Are there plugs I can buy to put in the holes where the Smog rail goes into the Intake Manifold? Do I have to make any changes to my carb? What about the line that goes from the canister to fuel tank? Looks like there is quite a bit to contend with. Am I making it more complicated than it is? Help!
 
The AP and associated plumbing can be removed. The carb does not have a ported vac fitting to supply vac to a vacuum advance dissy. Unfortunately the truck is equipped with a vacuum retard dissy, so that should not be connected to anything. Set the base timing to 10* at idle.
Keep the canister system as intact as possible. It provides a method to get air out of the tank without as much gas stanky, and allows makeup air back into the tank without the FOD.
 
You can check out my thread I just recently wrapped up my desmog - it was a bit more involved than I expected but I'm not a mechanic so had the pros help me some. Mine is a '74 so should be similar. Keep you smog stuff in the event you sell. Like @Racer65 said about stock...

Thanks a bunch. Do yoou have any issues with gas smell since you took it all out?
 
I will tell you desmogg'n my early '74 really made a difference. If you have your carb rebuilt by Jim C. (poster above) or 65swb45 they can drill the throttle body and install a vacuum advance port which will allow you run a NEW vac advance distributor available from Toyota or Trollhole, which seemed to make mine much more responsive.

I'm in Kalif, so I moth-balled all the smog stuff, just-in-case, 'cuz you never know with the bastids that run this town....

No smell of gas I kept my canister which everyone said to do. My cruiser smells less of gas than it ever has since I replaced the hoses and that stopped the small fuel leak.
 
Engine bay is a little cleaner without all that stuff that's a fact.
