Subaru Sump Plug Adapter & Dowety Seal

This is a Subaru Sump Plug Adapter and comes complete with a dowety Seal.

If you remove your original sump plug, you can replace it with this adapter which then allows you to run a drain back hose from your catch tank system back into the sump. Alternatively it can be welded into the side of the sump and used as an additional drain port.
