Couple of thoughts. That pump is way more than you need. Size the pump for your approximate hp level. The regulator is really nice and probably overkill as well. Search around aeromotives website and you’ll find some stuff more appropriate for your build. Mounting an electric pump high up and on the firewall is a no no. Electrics don’t like to pull fuel, they like to push it. So it needs to be gravity fed and way at the back. I prefer in tank pumps. Last thought, be careful mounting your regulator to the firewall also. Most racing sanctioning bodies don’t allow it because it is a safety concern and a serious one. The inner fender is a better location.
