Just finishing a 2056 build with weber 40's.
With the D-jet FI system on our 1972 there is a hose that came from an output nipple on the passenger side of the fan housing to input of the charcoal canister in the front trunk. The output return line from the canister plugged into the air cleaner. This system blew air from the fan housing thru the canister and I believe sucked the vapor out of the tank routing it back to the air cleaner. So with the carb conversion I would still like to vent the fuel tank vapors but where would be the place to do it? We could modify one of the new air cleaners and place the return line there, or maybe put a vent in each air cleaner and vent into both with a tee. Or just it safely somewhere to atmosphere. O I suppose eliminate the charcoal canister altogether, but then how does the fuel tank get vented? What have all of you done with this with the carb conversion. Thanks jjs3rd914 |

We will vent the fuel vapors into the carb air cleaners.So as to not favor one carb over the other we will use a tee and vent to both.. jjs3rd914 Anyone got a descent pic of dual idf's with such a set up? I'd like to see how people have addressed this. Are we adding fittings to the top hat/cover or from underneith? |
