I purchased this Atwood hand-pump oil changer for about $40 at a local farm supply store. It originally had a very thin vinyl hose that plugged into the larger clear hose shown in the picture.

I ditched the little hose and used a piece of 1/4 inch copper tubing. SO MUCH EASIER to install in the dipstick opening at the base of the engine block. No more guessing if the silly thing made it all the way to the bottom of the pan.

If the oil is hot, after 4-5 pumps and it will draw out the oil on its own. Works quick. 5qt capacity so I have a spare jug handy in order to fully empty the 440.

Only 5 quarts, so you'll need to empty it halfway through. Neat rig.

I got this one when it was on sale. The regular price is kind of high. It holds almost 7 quarts. It works much better than an old wore out "oil buddy" that I used to have...

Being a legendary cheapskate, I made one from an old, free (naturally) propane tank and some left over pipe fittings. I used one motor to generate the vacuum while sucking oil from the other one, then reversed the process. The tank holds well over 15 quarts, which I emptied out later in my shop. Nice and neat! And cheap. I really like that part.
