Re Charcole Canasters On 350 Tbi - Pirate4x4.Com : 4x4 and Off-Road Forum

Just finishing up a 350 tbi swap. And wondering if the charcole canaster is needed or should be bypassed?

When I put a high output 350 in my shop truck I brok off the connector for the canister. I bypassed it, has been that way for two years.

I believe it is there for emissions reasons. It "collects" gasoline vapors and (?)returns them to the tank?

There is a port on the throttle body that has to be blocked too. And you will have to vent your tank somewhere (open air i guess).
At first I didnt put a canister on my TBI swap, i just hooked the tank vent straight up to the TBI and when I had a full tank of gas and got on a steep incline, it would suck fuel up the vent line and flood the engine. I guess the charcoal canister prevents the liquid fuel from reaching the engine.

Got it done
Vent from the tank to canister
Line from canister to tbi simple sweet
Mounted under the battery tray

Thanks for the help

Ok I want to get rid of my charcoal shit box. I have a RCI fuel cell mounted in the bed of my jeep. See pic below. The top line to the right is going to the canister and it has a rollover valve on it. I guess I over filled it the night before i drove up to the Rubicon because half way up the mountain it was pumping gas into the charcoal box. So I want to get rid of it. What do I need to do with the lines. It has the 2.5L in it still.
