H2O-Stop Installable
Check your vehicle's compatibility before proceeding. Do not install on vehicles not listed in the official application list.
Check your model's compatibility on the Vehicle Compatibility page or the product data sheet.
Remove the fuel filler cap.
Check the internal diameter of the hole — it must match the selected H2O-Stop version.
Insert the H2O-Stop in the correct orientation as indicated by the arrow printed on the filter body.
Ensure the filter is fully and securely inserted into the hole.
Replace the cap or close the filler hole as normal.
Perform an initial controlled refueling and check that the flow is regular and there are no leaks.
Portable H2O-Stop
H2O-Stop Portable does not require permanent installation. It is used when refueling.
Keep the H2O-Stop Portable in its transport container until ready for use.
When refueling, position the H2O-Stop Portable at the tank's opening.
Pour fuel slowly through the filter—do not force the flow.
After refueling, return the H2O-Stop to its container.
Periodically check the filter's condition: replace if it shows damage or visible end-of-life.
Fuel Pump Protection
Installation of the Fuel Pump Guard requires specific technical skills. Rely on a qualified workshop. Incorrect installation can cause damage to the fuel system.
Verify compatibility with your model before proceeding.
Rely on a qualified workshop for installation.
The workshop must follow the technical instructions included in the product packaging.
After installation, perform a fuel system check before starting the engine.
Record the installation date and mileage for future monitoring.
Injection Protection
Installation of Injection Protection requires specific technical expertise in injection fuel systems. You must rely on a qualified workshop — do not proceed independently.
Verify the injection system's compatibility with your specific model before proceeding—consult the product data sheet or contact PurMotors support.
Trust a qualified workshop: the procedure requires access to the pressurized fuel system.
The workshop must follow the technical instructions included in the package and adhere to the specified torque and connection details.
After installation, check for leaks and proper fuel circuit pressure before starting the engine.
Document the date, mileage, and performing workshop for future checks and for the validity of after-sales support.
Drying Bag
Drying Bag helps dry wet gear. It's not an electric dryer and it's not a dry bag.
Completely open the Drying Bag and insert the wet gear.
Do not overfill: leave space for air circulation.
Close the bag using the designated closure.
Place the Drying Bag in a dry and well-ventilated area—not in humid environments.
Allow it to work for the necessary time based on the material and degree of wetness.
Do not expose directly to intense heat sources or prolonged direct sunlight.
Periodically check the condition of the gear during the drying process.
