I believe if the car ever has to go through a DOT safety inspection, or pass tech at a racetrack, there will have to be a solid "firewall" to prevent fumes from entering the passenger compartment of the car.
You are probably right, I've never been to the track so I don't know what requirements they have. No plans to ever go to the track either, but I don't want a safety hazard of my own making. I've seen photos of fuel cells in trunks with braided lines routed out of the trunk, is that a whole lot different than what I'm doing? I'm thinking about adapting a metal box with a watertight lid to fit over the pump/lines that would seal out any fumes and protect that area but still give access. This is my first attempt at something like this, I'm open to any advise...
