    I thought I would post about adding a vapor canister to my '64 Cadillac sedan deville. (Sorry it's not a wagon) I search the web and there are no aftermarket packages to install these on an old car. They have no effect on performance or mileage but they are neglected and removed a lot of the time because they aren't understood. I've installed a Fitech fuel injection system on the car so no more carburetor fumes.
    The caddies of this vintage had a propensity to spill fuel, when the tank was filled, out the vent line. So I wanted to save some cash, stop spilling fuel, stop smelling fuel and save the planet all at once.
    Here are a few pictures of the ongoing install. Still not finished

    The TTV valve only allows ported vacuum to purge the tank once the engine hits 128*. Ported vacuum only pulls from the canister while it's off idle and high vacuum cruise. It will be tee'd in behind the PCV valve so again only when that is purging the engine.
    The corvette part is to stop gas from flooding the canister and is also a rollover valve. I will be installing a restrictor before the roll over valve again to help prevent fuel from flooding the system.

    Seems like a lot of money and work to save a few drops of gasoline. Personally I like sniffing gas. But anything to save Canada.

    When the tank is full it gushes out. 5/8" vent line spills fuel like crazy. I'll be around $200 Canadian or $125 US funds. It's something I wanted to try, and of all the money I've spent on cars it's a drop in the bucket LOL. Plus the garage isn't going to be full of fumes anymore.

    If the car looks as good as the engine it will be worth the money.

    Don't worry. It isn't your fault. Blame it on Fisher Body and GM executives.

    I do now. It's about time the carburetor got put to rest. R.I.P., carb. It still looks tight around that steering gear. Are you planning headers for later?

    image.jpeg No plans for headers. Sanderson makes some but they need a big hammer to make them fit from what I've read. Plus no mounting bracket holes for anything. It's a stock engine with factory 10.5/1 pistons. It's been rebuilt about 7000 miles ago I just repainted and changed a few gaskets and seals. I also massaged the intake for the Fitech.
