Our Olds is going to be powered by a 400 + cubic inch, FAST fuel injected , Bullseye Power Turbocharged Olds engine built by BTR Performance , which means it's going to make alot of power. It also means the car is going to need a stout fuel supply to keep up with the engine. Today, we're looking at the components of our FAST Fuel System In A Box including the fuel pump, filters, regulator, y-block, and all the included wiring and fittings. We're also taking a sidebar to explain the mystery behind AN and NPT fittings and what those "dash" numbers mean.
