Review on Auto Meter 6107 Cobalt Mechanical Boost / Vacuum Gauge - Reliable Performance and Easy Readability! by Raul Fabijan

This sensor measures gain. It's a stiff nylon so it won't flex a lot without breaking/folding. It connects to a 3.5-4mm vacuum hose with a T-piece. The gauge seems accurate. I expected 5psi and got 5psi. Although it is quite thick, that is, deep. I have an Autometer A-pillar sensor and it doesn't fit flush in. just so you know I also wish it had multiple color options. I figured I could just change the color of the bulb, but the gauge is sealed. I chose to connect it with no power for the lights, but the sensor works.
