Info About Tube Sight
Tube Sights have been test fit on vehicles without the AC Accumulator ONLY. To install the tube sight, we move the 6AN coolant connection fitting to the back corner of the reservoir. We cannot guarantee that the tube sight and/or coolant fitting will clear the AC accumulator if equipped.

See What's Inside
Each Canister is double baffled prior to the outlet filter for maximum oil particulate separation.
Sandwiched between the two internal baffles, this 3M stainless steel filter mesh provides exceptional oil particulate separation, while still allowing necessary breathability and airflow.
Both canisters drain into the Breather Filter Can body, and funnel towards the drain valve.
Two 3" outlet filters provide the final method of oil separation. These filters are removable and servicable. They can be washed and re-used, or easily replaced when needed.
Removal of the filters also allows for flushing of the Breather Filter Can body. Simply open the drain valve and flush the can with a solvent such as brake cleaner or mineral spirits and allow to dry.
