ReplyNow that I think about it , if you did the pinch off way , your better off adding a shrader near the bad valve , otherwise you wont be able to flow nitro while brazing. Now you can pull a vac from both sides as well.

you could add a 1/4" tap. Use two pinch offs, cut out old filter and reinstall filter w/ shrader and pull a 5 minute vacuum. reform tube.
I'm not a fan of pulling vacuum through a TXV.
