Alternative air intake for expansion tank

[Stanley]

The gas tank's coming out for a clean-up so I checked the expansion/evap tank, the hoses were kinked or otherwise bad except a big new braided one the PO put out some bucks for but didn't bother to clamp. Anyway I want to keep the evap tank but upgrade the tank venting. Don't like the lil line going to the flow valve - if it's working it needs some vac before it pulls air. It's not venting - there's a big difference (watching clear fuel filter) when the gas cap's on or off. Have 73 with early SU's and K&N's.

Can I just hook up the lil tank per stock (good references in these forums) except take the top air intake line (with a small filter) somewhere else? Where would be a good place to run it ? Don't want fumes venting in the engine bay if possible.
