AUTOOL Smoke Machine Automotive Leak Detector, Evap Vacuum Smoke Diagnostic Tester, Pipeline Fuel Leakage Detector Compatible with 12V Vehicles

【Why Need It】For example: 1. The rupture of the vacuum hose will cause the mixture to be too thick, the idle speed will increase, the hot car will not start well, the engine will surge during acceleration, the fuel consumption will increase significantly, and the exhaust pipe will emit black smoke. 2. Blocking will cause the idle speed to drift, and the idle speed is easy to stall. 3. Air leakage in the vacuum tube will cause the engine to run weakly
【No Air Pump】Note: AUTOOL SDT103 does not have an internal air pump. External air supply is required for use. Connect shop air supply, connect 12V vehicle power, introduce shop air to the AUTOOL SDT103 fuel leak tester, turn the Flow Dial anti-clockwise to open the air flow, switch on the power at the back of the unit, then AUTOOL SDT101 smoke machine automotive will start to generate smoke.
【External Flow Meter】You can easily control the air pressure, because the air pressure of each pipe in the car is different. If the air pressu
