    I need the hard lines for a '72 Blazer that connect the tank to the vent standpipe and to the charcoal canister (the ones that mount to the rear most crossmember on the frame).

    Hi,

    I'm just curious why you'd want to maintain emission parts of your Blazer. Don't get me wrong, I think it's great some people try keep theirs rigs in clean factory shape (if that's what you;re doing)... it's just it seems that finding and replacing some of these odds parts is more hassle than it's worth, especially given that our pre-73's are SMOG exempt (for now anyway) in CA.

    i probably have what you are looking for(lots of parts trucks), but i have no idea what you are talking about. Sorry, are you talking about the gas tank vent tube that has the 3 lines going into it? anyhow email me at kilomanjaro63@hotmail.com if you are interested

    I'm in the process of redoing the Jimmy, and I know exactly what you are talking about. Looks to me like these 3 lines have relatively simple bends, and I am planning to duplicate thm in stainless. Should be no step for a master fabricator like you. Good luck.

    ErikH, the evaporative emissions equipment doesn't hurt anything performance-wise and can increase the life of a fuel tank by separating water from the air that's venting into the tank.

    Another common misonception if that there are vehicles in CA that are exempt from emissions standards. That is definitely not the case for anything built in or after 1964. Vehicles made prior to 1974 are exempt from the inspection, but not exempt from having to meet the emissions requirements. Our wonderful State Government is trying to repeal the inspection exemption and they are also trying to put remote-sensing equipment into place in order to bust those of us who have modified our vehicles. The remote-sensing equipment will be equipped with cameras and shoot photos of the vehicle and license plate numbers while recording the emissions levels. The vehicle will be ordered into the referee system for inspection if the measurements are too high (this is currently legal, but the exemption of mandatory inspection is yet to be repealed).

    Steve,
    Yeah, I was aware of the regs on the inspection exemption for our pre-74's, but I didn't realize the benefits of the emissions equipment related to the canister.

    I have a feeling that a well tuned, mildly modified V8 without emissions equipment would burn cleaner than an older factory engine with old emissions equipment. And it'd sure suck getting cited for running an aftermarket carb or manifold knowing this. I imagine the key to avoid getting cited by these remote devices is to avoid a radical cam (or rich mixture).

    I don't know about out in California, but in Colorado Springs my 72 blazed through the emissions test with my 383 and radical cam, no sweat..........

    Like to go sloppin' 'round in da mud in a rapid fashion....=)

    You're pretty much roght on there, ErikH. FWIW, my Trans Am passes smog even with a pretty wild cam and head setup. Part of the equation is in getting the tuning just-so, the other part is selecting parts and combinations of parts that have CARB EOs.
