I decided to cut down an old filter.
Just cut through about an inch up from the flange, remove the filter shit, TIG weld a plate that has a small pipe at one edge and attach a hose (hose needs to be positioned at the bottom once screwed on).
Very basic and pimative, but it works. Took me 20 min to make and no mess at all.
A very small amount of old oil may make it back into the system once you see the new oil, but with old oil still sitting in your sump, pump, motor and hoses this small amount aint gonna bother anyone.
