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 |

I had to fish one of my carbs out of a storage box to make sure I was remembering right that I could mount hose nipples on the bottom side. Yep, plenty of real estate to mount fittings under there. These were in an old Weltmeister kit I bought from the old Automotion in the 80s. The housings are K&N and measure 9"x5.25". I wonder if they are still available.

The housings in my picture/application are 7-1/2" by 4-1/2". Just almost too small for underneath attachments. But we will sure investigate when the engine lid/rain tray gets installed. Carbs and air cleaners bought from AA performance in CA. Linkage we made ourselves. |
