I'm trying to achieve a vacuum by sending air through the green tube, (in to out) sucking in air from the in/out blue tube. pulling the piston back to the end

Would this T valve work?

It's entirely possible, but the shape of the tubes affects the results. I have one of these that I bought for making a suction filter from tap water flow. I believe you need a nozzel so the air flow is introduced at smaller diameter than the tube it is blowing past. A tiny bit of googling would probably clear up this point.

I think the injector tube is too long. Try making it adjustable! and get rid of the interfering shape on the end of the air exit tube.
