Air Pump

Accelerate engine to about 1500 RPM and observe air flow from hoses. If air flow increases as engine is accelerated, pump is working properly. If air flow does not increase, check system for plugged or restricted hoses, proper pump belt tension, leaky valves or defective air injection pump.
