That looks like it would work well. Having the supply right on the bottom like that is gravity fed. Leaving it a siphon and it has to work against gravity. Do you have yours like that? Does it work a lot better than the siphon?
yup, that's how mine is. Only problem I have had was a piece of crud made it's way up into the gun. I literally use about 3 cups of material. I'll take a picture later.
