Enginebeginner✓ OP Confirmed

Problem

Power steering fluid leaking from the return port on the steering rack when using a Driftmotion 6AN return line adapter with a copper crush washer.

Power steering fluid leak at the return port on the steering rackLeak persists despite using a new copper crush washerLeak confirmed to be from the washer side of the fitting, not the AN fitting side

Root Cause

The Driftmotion 6AN adapter fitting was bottoming out in the return port before the copper crush washer could fully compress and seal. The standard copper crush washer was too thin to create a proper seal given the depth of the port.
