A fuel injection apparatus for a vehicle includes a throttle body having an air flow passage extending therethrough with a throttle plate mounted in the passage. At least one fuel injector is mounted below the throttle plate and above the intake manifold of the engine for cyclically injecting fuel into the air flow passage extending between the throttle body and the inlet of the intake manifold. A full time, closed loop feedback control system monitors exhaust gas content and adjusts the fuel flow based on the measured air/fuel ratio. A tank storing gaseous fuel at a high pressure is connected to the fuel injector via fluid flow conduits. An annular recess is formed on at least one location on the side wall of the tank. Annular shoulders are disposed on opposite sides of the recess and extend outward above the side wall of the tank. A mounting bracket is mounted in the recess surrounding the tank and is attachable to the vehicle to mount the tank to the vehicle. A fuel fill door sensor closes the fuel delivery path during refueling.

A throttle body fuel injection apparatus for injecting gaseous fuel into an intake manifold of an engine comprising: a throttle body having at least one air flow passage extending therethrough in fluid flow communication with an intake manifold and a movable throttle plate mounted in the air flow passage for varying the quantity of air flow through the air flow passage; cyclically operable fuel injection means; means for mounting the fuel injection means between the throttle plate and an intake manifold of an engine in fluid flow communication with the air flow passage extending through the throttle body to the intake manifold for reducing noise; and control means, including throttle position sensing means and engine speed sensing means, for cyclically actuating the fuel injection means to inject fuel in pulses of timed durations and cyclic frequencies variable in response to variations in throttle position and engine speed, respectively, sensed by the throttle position sensing means and the engine speed sensing means, for establishing air to fuel mixture ratios.
