The prior owner of my lakester used a port-injector system, but my engine will have a blower/injector/scoop that will extend somewhat above the existing roll cage and body. In another thread I stated that I intend to assure that the little gasoline primer tank is inside the cage. But what about the injector with its alky system- nozzles, hoses, barrel valve, etc.? Have I missed a rulebook section that clarifies these requirements?
