I have an odd question.
Has anyone used a quick drain, like the one Van's sells, and then put on a back up valve?
I know that you connect a tube to the quick change valve when you drain the oil. But in theory, you could connect up a flex tube and connect a 1/4 turn ball valve. Hose clamp the flex tube to the drain valve and to the ball valve. Then you just have to connect up a drain hose to the ball valve when changing the oil. The tubing between the drain valve and the ball valve would have to be able to handle the heat.
Any thoughts?
