fuel tank lines?

Thanks for this info!! Ok, so, I need to leave that 1/4 inch line open and high to vent the tank, i understand this, but do you know of a tiny air filter type deal i can put on it so its not just wide open?

You could just use a small plastic or metal 1/4" fuel filter..............

One way depending on your fab skills is to plumb it into the non pressurized section of the PCV/ crankcase breather system. Some cars actually had a "multi" port breather on one valve cover. One big line went to the air filter bonnet, and it had a couple? of small fittings which would work well for this

Here's one now.......
