Fuel line question

clhyer said
Terry,
You are correct regarding the second line going to the charcoal canister. Will I not need this line? If I do not use this, how do I vent the gas tank, or prevent vapor lock?
Second, my 318 is stock. I have no plans to race or anything. Will there be a benefit to the 3/8 line? IIRC they are the same price, so it's just getting the best parts for the job.
Thanks,

Most of the original system is detailed in the factory shop manuals. Read both the section on fuel, and emissions. This system changed almost every year. you can download the manuals FREE from MyMopar. Some of those came from the guys here on FABO

The other line to the cannister is for emissions. Keep it or do away with it. With a vented gas cap or vent line in the filler tube you'll be fine.

If you "do away" with it you'll have to something additional for venting. PLEASE reconsider using a vented cap. That's a "quick way" to end up with paint on side of the car

In my opinion, the best way to vent a newer tank with "did away" evap lines is to construct the vent system exactly like the 69/ earlier cars did.....a vent tube in the filler neck

Other guys simply leave the evap line up front, and leave it "up high" so it cannot siphon. I believe the earlier cars ---70 CA only and 71--- had no carbon can...........they "teed" the vent line into the PCV breather
