My 93 FXDWG has what appears to be a small vent hose connection with a rubber hose on it on the top front of the fuel tank under the dash. The hose goes from the tank to a small black plastic canister about 3/4" in diameter and from there disappears under the fuel tank.


Is this a vent hose connection? What is the small black plastic canister for? What would be the consequences of the hose or canister being stopped up or leaking air (I have no fuel leaks)?


Thank you!

Thank you.

 

I have a 01 fxdl ..that hose on mine vents the tank ...if ya put too much gas in it will vent it to the frame right behind the fuse box and out the bottom of frame ..

 

It's a 1 way check valve. Vents pressure out - keeps fumes in.
