Air Injection Hose/Tube: Testing and Inspection

Secondary Air Injection Components:

INSPECT

1. Hose or pipe for deterioration or holes.

2. All hoses or pipe connections, and clamp tightness.

3. Hose or pipe routing. Interference may cause wear.

4. If a leak is suspected on the pressure side of the system or if a hose or pipe has been disconnected on the pressure side, the connections should be checked for leaks with a soapy water solution. With the pump running, bubbles will form if a leak exists.
