The Powerjection III is offered in four versions. The PN 70020 and PN 70021 versions (cast and polished finish, respectively) come with software, wiring, and sensors, but do not include the fuel components. You'll need to supply your own fuel pump, filter, and regulator. The PN 70026 and PN 70027 versions (cast and polished finish, respectively) include the fuel components, but you still need to supply the fuel feed and return lines from the tank. Professional Product offers its fuel line kit, PN 70107, which we'll show you next time.
