A while back I installed a Fumoto valve to make oil changes easier/cleaner.
I'm still trying to come up with a solution for the oil filter removal, which can be a bit messy. So far the best method is using a nail to punch a hole in the lowest point of the filter and then let it drain first. This works, but still requires a drain pan or a funnel and jug.
I'd love to find some type of self piercing/tapping drain valve that you could attach a rubber line to.
I found a product like this for aircraft engine oil filters that looks like it would work, but the price ($40) is a bit more than I'd like to drop on such a luxury. Anyone have any ideas?
I found this one that is cheaper, but it doesn't look like the company is still around.
Also found this video, which really to me is the best approach, a strong magnet, stick to the bottom of the filter, tap with a hammer to pierce, open the valve. But, doesn't look like the guy is still around or making them.
