Charcoal Canister Removal

[rebootej]

I have a 74 Satellite Sebring with a 318. We removed the charcoal canister and line from the gas tank during the rebuild. I currently just have a hose attached to the outlet on top of the tank.

What have you guys done when removing the charcoal can? Can I plug it off or will this cause issues? Put a filter on the end of the hose? Any help would be greatly appreciated.

So, if this in only short term(I wouldn't do this long term), you can cap off the vapor line, just make sure however, the tank can breath otherwise when it gets hot, it can over pressurize and/or you can end up with vapor lock situation or high pressure when you take the gas tank cap off, release of a lot of fumes or fuel. Be aware that having an open line will let fumes out to the atmosphere.

Thanks idrive, what about long term? just put a filter on the hose and attach to trunk floor? Im not going to run a charcoal can.

I kept my Charcoal can. Just have the gas tank vent line hooked up to it.

Every vehicle in the US was this way until the late 60's via the vented gas cap, and did seem to kill that many grasshoppers or gophers. You may smell a little fume on a hot day. Back when it was normal... When overfilling the old tractor it would even seep a little gas out of that tiny little hole.

I cant really recommend to you what to do since having an open vent is a safety issue. Also, disabling emission control items on cars in California, not sure if that will be an issue for you passing state inspections, but it might be.

Just curious what is your reason for removal, having it does not have any impact on performance?

Luckily the car is Ca smog exempt so no issues with the emissions. Pulled it off years go when we put a crate engine in the car. Left it off with the latest rebuild because I like the way the engine bay looks with out it. Less clutter. Can I close it off and put a vented cap on?

What about using a vent from a rearend on a short piece of hose back by tank? That was my thought for my car. I do not have a charcoal can and need to do something with mine as well. You could always run that hose over to frame rail and secure it there.If anyone has any other ideas I'm open to suggestions as well.

If you use an aftermarket line vent, just make sure its mounted higher then the highest point of the tank, including the neck, otherwise you will get fuel leakage from the vent tube.

Thank you!

Old post, but just for the record, we don't have safety inspections in California. As well, the car is smog-exempt. The issue I'm facing is that the charcoal canister is old and no real way to rebuild or replace, so even if you actually have the external bowl vent on the carb (good luck with that on most aftermarket carbs), you still need to put some sort of fuel filter to prevent charcoal breaking free and ruining the carb. So seems even if you want to do the right thing and run the charcoal canister, lots to contend with.

Out of curiosity, WHY did you eliminate the charcoal canister and the vapor line to the tank? The vapor storage system is a static device and does not "hurt" the engine's operation and most importantly, provides a fuel tank vent provision. By eliminating the vapor line to the tank - canister, the fuel tank has no vent; the tank must be vented to allow for air to come in as the fuel level drops. With a vapor storage system, the fuel tank cap is not vented....the vapors must be contained or stored, by eliminating the vapor line to the tank via the charcoal canister you run the possibility of collapsing the tank UNLESS you vent the tank. Just my opinion of course.

Sorry for the high-jack.
The tank vent/fuel vapor problem is easily
overcome by installing a charcoal filter
and bug screen. The canister is the same as
used on a Corvette brake booster hose, the
screen is typically used for boats but is
available thru Summit.
This has been on my truck for a year, in the
garage, no hint of gas fumes. And cheap.

You could grab a charcoal cannister from a junk yard and make it work, if you really wanted one.
