Details

Clean and Test Four Fuel Injectors at Once

The V308 cleans fuel injectors in a heated ultrasonic bath and tests them on a four-cylinder flow bench, for gasoline car, motorcycle and boat injectors. Diesel injectors can be cleaned but not tested.

  • 1 Cleaning + 9 Tests
  • 4 Injectors
  • 0–7500 r/min
  • Heated Ultrasonic Bath
  • Aluminum Alloy

Key Features

  1. Heated Ultrasonic Cleaning

    The tank heats the cleaning fluid to remove carbon deposits faster and improve the cleaning effect on injectors.

  2. Nine Test Functions

    Idling, medium speed, high speed, accelerating and shifting speed tests, a leak checking test, and idling, medium-speed and high-speed spray value tests.

  3. Real-Time Monitoring

    An LED display, pressure gauge, graduated glass tubes, liquid level gauge and control panel show what is happening during each test.

  4. Easy Fluid Recovery

    Drain valves let you recover used cleaning fluid and testing fluid after use.

  5. Short-Circuit Protection

    If the machine short-circuits, the internal fuse trips and shuts it down to prevent electric shock.

  6. Aluminum Alloy Build

    Lightweight and strong, with good airtightness and corrosion resistance.

  2. Run ultrasonic cleaningStart the ultrasonic system to dislodge buildup inside the injectors, then recover the remaining cleaning fluid.
  3. Mount and checkFix the injectors on the main machine to test for resistance, shorts and current draw, and fill the glass tubes halfway with test liquid.
  4. Test on the flow benchRun the leak, spray pattern and flow rate tests, then retest all functions.

Good to Know

Caution
  • Do not start the ultrasonic cleaner before adding the cleaning fluid, as this may cause damage.
  • Never put the pulse signal cable or its connector into the cleaning fluid.
  • Do not run the ultrasonic cleaner continuously for more than 30 minutes, as this shortens its life.
  • Do not use corrosive fluids for testing.
Care
  • Medical alcohol or paraffin can be used as test fluid; if the machine will sit unused for a long time, recover the test fluid after testing.
  • Add only enough cleaning fluid to soak the injector needles.
  • Unplug the machine when not in use.

Have jusr recieved my package less than 48 hrs after placing the order. Very quick delivery. A1. Came well packaged with no signs of damaging to parcel. Well done to delivery company. Wasnt sure what fluids to use for the cleaning and for the testing. Communication with the seller was excellent and very helpful with links given to the appropriate fluids. Also had good comms with the manufacturer, who was very helpful too. Looks to be a good machine. Waiting for fluids to see how well it function

Kevin

This fuel injector cleaner is ready to use right out of the box—I specifically bought it to remove carbon deposits from my fuel system. It performs comprehensive tests including idling, acceleration, leaks, and fuel injection quantity, with real-time data displayed on an LED screen. Fuel injector testing can be done using 99% medical alcohol and paraffin. I can clean and test four fuel injectors simultaneously—the ultrasonic + heated cleaning function quickly removes even the most stubborn carbon deposits.

Lyndon M.

This is a very efficient tool with excellent cleaning results. I’ve equipped my workshop with it, and it’s been a huge help. My work efficiency has greatly improved. With this tool, my workshop operations are more reliable, and more and more customers are coming to me for fuel injector cleaning.

The new blue colour looks better than the green model, the quality is as good as ever, buying an extra injector cleaner helps me to be more efficient and is recommended.
