Hello everyone!
I am an FBBO guy (same username) but have had 67, 68, and a 69 Darts in my younger days.
A few years ago, I retrofitted a 68 Satellite based on slantdixdan's fantastic article at Allpar. It worked great but I now live in the foothills of Los Angeles with lots of hills. After an almost full tank, the gas from the tank vent got into the carbon canister in the engine compartment since there was nothing to prevent the gas from entering the canister from the vent line while going up and down hills. So, what I did not think about was how do I replicate the vapor separator portion / over fill check valve part I see in later 70s A/B body diagrams.
What do you recommend in between the tank vent and the carbon canister to prevent gas from getting in carbon canister?
I know that there is GM product for old vettes and modern Fuel Discriminator Valves. The GM fuel vapor separator valve part number is 353162. There is also a Discriminator Value DV100 from Fuel Safe and I'm wondering if that works as an overflow/gas valve as well.
Any help or A Body part model part that I am not aware of would be a great help! This has been a four year journey for me. Prior to moving California, the retrofit worked great. But since moving here almost overfilling my tank, I never thought about needing a gas/vapor valve.
Thanks and any help is welcome!
