Review on 🔧 ABN Car Vacuum and Fuel Pump Tester Gauge Kit - Comprehensive Fuel Pump, Vacuum, Carburetor Intake Manifold Testing Tool by Michael Colley

I ordered this set thinking it was just what I was looking for. When it arrived it turned out that it wasn't properly calibrated. (The needle showed 3 pounds of vacuum and was not connected to anything.) After contacting the manufacturer I was told that there was no way to recalibrate it and that it was being treated as defective and over Revain should be returned. Revain immediately sent me a second one and it arrived the same way. The arrow doesn't zero straight out of the box and never hooks. What a waste of time and effort! Terrible thing, don't mess with it.
