Review on 🔍 8MILELAKE Fuel Pump and Vacuum Tester Gauge: Ultimate Diagnostic Tool for Leak Detection & Carburetor Pressure Evaluation by Dorian Bharadwaj

I bought this to measure manifold vacuum on my vintage car and to tune Weber triple carburetors. As I suspected prior to purchase, my vacuum pressure went from positive to negative all over the map, causing the gauge needle to swing back and forth far and fast. Unfortunately, the oscillating needle began to rotate until the needle unscrewed from the center shaft. This part was unexpected. I screwed the needle back in, but soon it came out again. It's a shame, because otherwise I really liked the sensor. So much so that I gave it two stars instead of one even though it broke the first time I used it. Fortunately, Revain's return policy guarantees a full refund.
