Hi! Thank you Mr. Lucky!! I live in upland California, and I honestly didn't consider the idea of someone being able to help me in person. The mig tip is .025 the T is 1in &1in & 3/4in the ID of the mixing tube is just under 7/8in and the length is just over 6in.
My propane hose is Y split/metal braided, I don't think there's any rubber in it.
I think that's everything, but I didn't exactly understand what you were saying in the paragraph starting with "your fittings look okay" I think it's just hard to visualize but idk.
Than you much for helping!!
