[C320-list] Oil changing pump kit

[Warren Updike]

Bruce, on my Perkins M30, there is a pipe from the bottom of the sump that comes up alongside the engine by the oil filter.  It has a treaded connector with a pipe nipple in it.. To change the oil, I replace the nipple with a threaded hose barb, connect the pump hose to that and pump.  It takes about 5 minutes or so to suck out 4 quarts.  It's easy and clean.  When done, I unscrew the hose barb, replace the nipple and go dump the oil at the marina.  

Apparently, Yanmar engines don't have such a pipe into the sump.  Some have replaced the drain plug with a connector and a hose permanently installed by which the sump can be completely drained.  However, leaving a hose and connection in-place is inviting disaster.  I don't know that I would do that unless the connections were threaded and the hose was a copper pipe.

BTW, commercial fishing boats often have tanks of clean and used oil connected by pumps to the engine.  They can shut-down and change oil in minutes and be back up without getting their hands dirty.  All connections permanent, throw some switches and your done.
