I'm in the process of putting a 383 sbc in an RX7 and am wondering about the tank vent. I've removed the charcoal canister underhood and removed the in-tank elec pump and installed a larger line. I'm using a mech pump and wondered if using a vented gascap will work for a vent. I also installed a Holley blue pump for the nos system. Will the vented cap be enough? I don't want to run short of fuel and lean it out. Any ideas?
