We only sell a single hood mount bracket now. Dual weren't selling good enough to justify another run of them. I got the pressure gauge on ebay, goes to 200 lbs. Not sure how long it will hold up to meth but have had it on there for a while now without any issues. Don't forget, Julio has an electric gauge for his system now. Didn't see it on his site though but there was a thread on the alky section about it. I did this well before he came out with his setup.
