do i need these?

I drove my 74 mav without the carbon canister, always smelled like a fuel leak.. I looked for the problem for 4 years..lol.. I stumbled on to the missing canister when I started my fuel tank upgrade in the 71,never knew I needed one, but can tell you I wish I had it.. The fuel smell drove me nuts...My new setup is vented though the gas cap.. Find a newer and smaller one and relocate it to the back if you want to clean up the look under the hood..JMO

 

oh so the charcoal canister is suppose to be connected to the air cleaner? there was nothing connecting it to anything except the line from the gas tank so what should i do keep it and run what lines from the top if the canister? anyone have a pic of one that still uses it or where i can reroute the line to get rid of it

 

OK so...everyone that has one hooked up please post a pic. of both ends...

Sure, if you want to be anal about observing all federal mandates, leave it all in place. I guess you NEVER exceed the federal mandated speed limits either. Or cross the street outside of a crosswalk. Or violate any other laws. As for the hose to the aircleaner, nothing at all happens other than the engine sucking the fumes into the cylinders soon as you crank the starter. I've had it hooked up this way for 7 years now. Never had an explosion from a backfire either. The fumes go into the engine before that will ever happen. The only way you'll have a backfire explosion is when fuel puddles on the carb top, and then have a backfire, that's not going to happen with the hose routed from the tank vent, unless you park the vehicle with the front end at an extreme downhill angle and the tank is full. In that case, you'd be stupid to park like that in the first place. Chances are in this scenario, the engine's not going to start anyway, as it'll be flooded to the point where the plugs are saturated and will not spark. You'll have a better chance of the starter setting it off. All this is an extreme situtaion, that's easily avoided by anyone with an ounce of common sense.

 

ok so ill just answer this im going to keep it so where do i put the hoses comeing from the top of the canister there is two holes for hoses...

 

one of those hoses goto the air cleaner. the other i think is susposed to have a platic cap on it.

 

:16suspect Nope, we all toss that junk in the trash. And funny you should mention it's got a pressure relief. That's also going to be an explosion hazzard.

 

I guess you've never seen what these engines run in marine applications for aircleaners. They're not much, just a metal screen that contains the fumes that build up when the engine's not running. And guess what ? :16suspectThey work to contain backfire- fires. The carb vent tubes are curved in a J formation, directing any excess fuel from a stuck needle/seat back down into the carb throats. An aircleaner serves the same function, only it's designed to clean the incoming air better, as boats aren't known to be run in dusty conditions. The engine fires associated with carbs were almost always the result of the engine run sans the aircleaner assembly or the cleaner lid missing. Every one I witnessed was such. In fact back in east Texas in the 70's, that was the sure fire method to rid one's self of an unaffordable vehicle note. Remove the aircleaner lid, retard the timing, pump the hell out of the gas pedal, and crank her over. Then floor it once the engine fired off. Then call the fire dept. and then insurance company.

 

thanks guys when i put the motor back in ill put it all back together .... painted engine bay today so progress

 

Watch out federal gov't, mavericks kill trees. What a stupid law. I have never seen this in any of the cars i helped part out, i dont think they would even know what to look for?
Anywho, welcome to the forums and good luck with your canister.

 

..or without it in my case...
