The plan is to have a seprate fuel system tied into the stock one. Fuel wont be pumped as vapor. It tends to rise in pressure when vaporized anyway. We have a stand alone fuel injector system at the shop that can control 1 injector. The plan is to inject the fuel prior to a copper or stainless line that runs across the exaust manifold then through a nozzle pre throttlebody. No vapor lock that way.
