BMW E34 M5 S38 - Emissions/Smog Pump Restoration

This video shows the complete restoration of my s38b36 Denso 084100-1000 (BMW Pn 1 312 484) emissions/smog pump. There is little info about these pumps online, and due to the items now be NLA and spare parts rarely available, I thought I'd make this video in hope of helping others in the future!
