AirSensors TBI Fuel Flow Path Diagram - EFI Fuel System Component Layout

This document is a black-and-white photograph of a display board showing the complete fuel flow path for an AirSensors electronic (throttle body) fuel injection system. All major components are physically mounted on the board, connected by fuel hoses, with printed callout labels identifying each part. Components shown and labeled include: the AIR INLET PLENUM (a finned air cleaner assembly with flexible intake duct, bearing the AiRSensors logo), the THROTTLE BODY WITH INJECTORS (a four-bore throttle body unit), the FUEL PRESSURE REGULATOR mounted at the throttle body, the FUEL TANK SENDING UNIT with in-tank pickup, the FUEL FILTER-PRIMARY, the HI-PRESSURE ELECTRIC FUEL PUMP, and the FUEL FILTER-SECONDARY. The hose routing illustrates the flow of fuel from the tank sending unit through the primary filter, the high-pressure electric pump, and the secondary filter to the throttle body injectors, with a return line from the fuel pressure regulator. A reader can learn the order of components in the AirSensors TBI fuel delivery circuit and how the supply and return lines are routed, which is useful when installing or troubleshooting this aftermarket fuel injection kit. No year, model, part numbers, or specifications are printed on the document itself.
