Inspecting Element

1. Hold a bright light inside element and check carefully for holes. Discard any element which shows the slightest hole.

2. Be sure outer screen is not dented. Vibration would quickly wear a hole in filter.

3. Be sure rubber sealing surfaces are in good condition on both ends. If damaged, replace element.
