[C320-list] Changing Oil in the Perkins M30

[Warren Updike]

Alan, I found the threaded barb in our marina store. I took the plug from
the tube with me and matched the threads to the barb and to the hose to the
pump. I don't have the dimensions; but, it is apparently a standard size. 
I wasn't aware the Perkins even had a drain plug on the pan.  I'd be
concerned about a permanent hose connection to the pan; but, that's just me.

Warren - Great suggestion using the tube as a 'vacuum extension'.  I've
always fished my oil pump's small flexible hose down the dip stick tube.  My
only challenge (which can take considerable time to get the 'just right'
placement) is getting the tube past the screen in the pan (not to confuse
anyone, the screen is not over the tube opening).  If you are getting 3 1/2
qts out through the tube, and assume something slightly less than 1/2 qt in
the filter,  you are pretty much draining the pan dry since 4 qts is a full
fill.  I should have added an oil drain kit by replacing my drain pan plug
when I had the engine jacked up for motor mounts.  I have seen on Hunters a
neat set up with a small electric oil change pump (not vacuum) permanently
installed and directly piped to pan sump.  Very cool (a separate topic,
Hunters have some very cool features and do not seem to receive the respect
they deserve.  Like Catalinas used to be, well targeted towards a specific
type of customer and price point.  Anyone care to comment?).   Where did you
get the rubber barb, do you have a p/n?
