Installing a new tank in our RR .
To simplify the system, (this on a 99% street 620 HP big block)
can we block the 4 nipples coming from the tank that was part of the emission set-up?
WE are using an electric pump sucking from a 3/8" sending unit with a 1/4 " return nipple
we are not using either.
Does this now require a different filler cap (vented or not). EDIT: In rethinking, I guess a vented cap is required....
Any other considerations we should be aware of?
Thanks, Joe

Yes you can plug them all off if your not using the original venting emission system that vented tank to charcoal canister or the crankcase. But if you block them off you have to vent the tank some how by either a vented gas cap or a tank vent somewhere. On my sons 72 Dart I eliminated all the tank emission venting system and the charcoal canister and run a vented gas cap. Course on hot days in the garage you may smell some gas fumes since they will be vented to atmosphere. On my 63 I use a 3/8 sending unit and a vented gas cap. Ron
