bypassing charcoal canister?

[sbx22]

What happens if I bypass the charcoal canister and hook up the fuel fume line straight to the carburetor vacuum? I think my evap canister has a leak, i can hear a hissing sound from it. Any short/long term problems with this?

The biggest problem youmay have is driveability issues. The reason isbecause of the already vaporized fuel that you willbe introducing into the engine but also you have a fuel suply issue as well if the engine manages to place the tankintoa vaccum it can make the pump work harder and even burn up. If you don't have to go through emissions then you can just unhook it if it is causing you problems but you will most likely have that gas odor like you smell when around older carbed vehicles. Oryou can just try replacing the purge valve. Its faitly cheap.

yeah, i have had it unhooked for a couple weeks now, tired of smelling the gas fumes in the cab. I just want to fix it now. No smog for me either. I don't think the purge valve has anything with what I intend to do. Anyone else chime in?

I have mine hook straight to the ported vac port on my edelbrock carb. No issues yet

I have done the same as 454Man.

I just finished pulling out the 350 CI in my 79 GMC, and installed a newly rebuilt 454.

Removed all the smog items, including the canisters.  I routed the two gas tank vapor lines, which previously went to the canisters, directly into the front of the Edelbrock carb.

It has been running fine for about 2 months, and no vapor fumes.
