Hi. Hope this helps. What we do at
www.wetstar.com is to provide for an adapter donut (if you have a spin on oil filter) with a side port fixed with a theaded nipple and controlled leak (as easy as replacing the oil filter), pass through a Parker-Hannifin bypass filter with a bracket (nice compact size) and go directly to a properly tapped/threaded drain plug. Alternatively, we provide the plug with a male (small end) quick disconnect to undo the drain plug for and oil change once is disconnected from female connected to the return hose. Easy install, now if you have a cartridge then the access is a bit more complicated sending unit, port, and ....... Later....
