I moved my firewall penetration to the right side, mostly to reduce heat load on the fuel, but also to make it easy to access. The primary fuel line runs forward along centerline to the base of the firewall, then right in front of the pedals, then up along the edge of the firewall, then penetrates the top of the footwell. It's then a super-easy route to the fuel pump. Thousands of words attached.
