Vilter HPLD CO2 system oil filter change

Come with me and replace the oil filter on a Vilter HPLD CO2 package. It is a pretty typical and straight forward procedure with a couple of differences with the filter housing itself. The CO2 housing is built to withstand the high operating pressures of CO2 trans-critical systems and has heavier bowl with a different type of securement and seals (an o-ring AND a Teflon ring).
