Fuel injection tank... vent line? I'm running a Spectra Classic injection tank with dual walbros put in. Before I did this modification, I noticed that the tank would build up pressure as ambient temperature increased and decreased, which was prevalent when I took off the fuel cap.
I know the OEM systems use an EVAP setup, but I was wondering if I need to have a vent line to alleviate this pressure, in lieu of an evap system?
Also, is this vent line going to let vapors out and create a dangerous atmosphere under my car while it sits in my garage?
I set up a 1/4" hose barb with a sort of breather muffler pipe fitting on the end that I'll have up above my rear axle for the vent line.

You need a rollover valve. Its an open vent that closes itself if the car flips over so that fuel doesn't leak.
Summit sells remote mount ones. Tanks Inc has a fairly cheap one that you can drill/thread right into your tank. The only problem with not having an EVAP is that you might smell gasoline when near the valve, that's why most of them have a barb fitting for a hose so you can run a remote charcoal canister.
