Plan is to install a Gen 3 5.7 into a 1973 Cuda. I purchased a Spectra EFI tank from RockAuto. It came with a Walbro GSS342 pump. Although the tank is of original design it seems like a decent setup for what I am looking for (just a nice day driver) especially for the price. My question is, this tank has the original 4 vent ports on top. The original setup had those vents plumbed to a manifold then a single vent line brought to the evap system in the engine compartment. My thought is to just cap 3 of the vents, install a rollover valve in the 4th and plumb it up to the engine compartment. Thoughts? any other solutions have haven't considered?
