Review on Mr. Gasket Silver Fuel Block with 0-15 PSI Pressure Gauge - High Quality and Precision Measurement by Yung Kaelin

I got a Weber for my Mazda B2200 and installed it to throttle the electric fuel pump. The first one I got left "no" gas regardless of the setting. I sent it back, got another one (and this time with a pressure gauge) and it was off on the pressure setting at about +3psi. So I got one from a local store which was cheaper than shipping it back, it works fine (at 0.5psi) and after a year I've had no problems. Guess that's the triple charm. My 2 cents, buy this locally, it might cost a few bucks more, but if you need to return it, it's a lot easier. And your car is not idly waiting for a new one.
