Feature
●Exhaust Back Pressure Test: This gauge easy to to test pre and post catalytic converter back pressures, check exhaust for clearance issues, helps identify restricted exhaust and melted cat converters. no guessing about plugged exhaust.Removed O2 sensor and screw gauge and adapter into sensor hole. Started truck, accelerate the engine to 2500r/min, if gauge read less than13.8 Kpa pressure, showing no blockage.if greater than 13.8 Kpa, means have blockage
●Check Fuel Pump Pressure: This vacuum gauge could checking fuel pump delivery pressure, only mechanical fuel pump systems, not to be used to check fuel pressure on electric fuel pump systems, verify fuel mixture settings were correct, found the vacuum leaks, tuned the carb, got a good idle speed
●Check Manifold Vacuum: Use this vacuum gauge measure the manifold vacuum pressure, helped you troubleshoot the system and find the failed component. Start the engine and warm up the engine temperature to between 75-85 degrees, turn off the engine, connect vacuum gauge, Started let the engine run in idling conditions, and ensure the speed is around 850r/min, if guage read less than 53Kpa, indicates that the system has a leak
●Digital Display Gauge: Our vacuum gauge is digital display, the unit is Kpa and mbar, you can switch between two units, digital dial will more direct and accurate show pressure than needle, and rubber cover protect in sueface, this tool not come with battery
●Complete Kit: This kit have 7pc different brass cone, and 4pc different plastic cone, and 2pc different adapters, so you can connect different part, make this vacuum gauge multifunction, the hose 48 inches, all the tools put in a plastic case, easy to storage
Description
Exhaust Back Pressure Test and Check Manifold Vacuum
How To Test Exhaust Back Pressure
- Removed O2 sensor and screw gauge and adapter into sensor hole. Started truck.
- Accelerate the engine to 2500r/min, if gauge read less than13.8 Kpa pressure, showing no blockage.
- If greater than 13.8 Kpa, means have blockage.
How To Check Manifold Vacuum
Use this vacuum gauge measure the manifold vacuum pressure, helped you troubleshoot the system and find the failed component.
- Start the engine and warm up the engine temperature to between 75-85 degrees, turn off the engine.
- Connect vacuum gauge, Started let the engine run in idling conditions, and ensure the speed is around 850r/min.
- If guage read less than 53Kpa, indicates that the system has a leak.
Digital Display Gauge
- Vacuum gauge is digital display, digital dial will more direct and accurate show pressure than needle.
- The unit is Kpa and mbar, you can switch between two units.
- Rubber cover protect in sueface, this tool not come with battery.
