Clean the fuel pump filter

To clean the fuel pump filter on a 2010 Kawasaki Teryx, you'll first need to locate the fuel tank and the fuel pump filter. The fuel tank is located beneath the passenger seat.

Once you've found the fuel pump filter, you can begin the cleaning process. Here are the steps to follow:

• Remove the fuel pump filter from the fuel tank.
• Visually inspect the filter for any debris, dirt, or silt that may be clogging it.
• If the filter is clogged, use compressed air to blow out any debris. You can also try using a mild detergent and a soft-bristled brush to gently clean the filter.
• Rinse the filter with clean water and allow it to air dry completely before reinstalling it.
• Reinstall the fuel pump filter securely, making sure all connections are tight.

It is important to note that cleaning the fuel pump filter may not always fix the issue. If the problem persists, you may need to replace the fuel pump or seek professional assistance.

Additionally, regular maintenance and keeping the fuel tank clean can help prevent future issues with the fuel pump filter.

Clean the fuel injectors

To clean the fuel injectors of your 2010 Kawasaki Teryx, you can try the following methods:

• Use a 3-in-1 fuel additive: For this method, you will need to use a general 3-in-1 fuel additive. It is recommended to use one ounce of the additive for every gallon of fuel. A suggested product for this is THE Royal Purple Max Clean, which can be found on Amazon. Adding this to your fuel will help clean the engine and remove hydrocarbons, restoring power and efficiency.
• Use a throttle plate and carb cleaner: You can also use a throttle plate and carb cleaner to lubricate the throttle and carburetor. A recommended product for this is the 3M Throttle Plate and Carb Cleaner, also available on Amazon. This will help remove residue and lubricate the throttle body, increasing performance.
• Use Seafoam: According to a Teryx forum user, running a can of Seafoam through the fuel system can help clean the injectors and improve performance.
• Change your spark plugs: Sometimes, the issue may not be with the fuel injectors themselves, but with the spark plugs. It is recommended to change them regularly, as dirty or faulty spark plugs can cause similar issues to clogged fuel injectors, such as reduced performance and difficulty starting the engine.
• Use a gas treatment: Another suggestion from a Teryx forum user is to use a gas treatment called Pri-G, which is supposed to be better than Stabil at handling the ethanol in modern gasoline, which can be harsh on fuel injectors.
• Use ethanol-free gasoline: Ethanol in gasoline can be harsh on fuel injectors, especially if the vehicle is not used regularly. Consider using ethanol-free gasoline or adding a fuel stabilizer to your tank to help keep your fuel injectors clean and prevent clogging.
• Clean the fuel injectors manually: If the above methods do not work, you may need to clean the fuel injectors manually. This involves removing the injectors from the vehicle and using a specialized cleaning kit or ultrasonic cleaner to flush out any debris or buildup. You can also send your fuel injectors to a specialized shop for cleaning and flow testing.

Check the fuel tank vent for obstructions

To check the fuel tank vent for obstructions, you must first locate the vent itself. The fuel tank vent is what allows air to enter the tank as fuel is consumed, preventing a vacuum from forming. This vent could be located on the fuel tank's cap, designed as a small hole or a valve built into the cap. If you have an external fuel tank, the vent is typically found on the cap. However, if you have an integral tank located under the floorboards, you may need to remove a fuel tank access panel or open the floorboards to locate the vent, which is usually found near the top of the tank.

Once you have located the fuel tank vent, you can proceed to inspect it for any visible obstructions, such as dirt, debris, or clogs. It is important to ensure that the vent line is free of any blockages, as fuel or condensation can get trapped in the line if it is not properly vented. This can lead to the build-up of pressure or vacuum in the tank, which may cause fuel and/or odour to come from the vent line. In some cases, this trapped fuel could even cause damage to the tank if the pressure builds up significantly.

To clear any blockages from the fuel tank vent, you can use a clean cloth or compressed air. It is important to ensure that the vent is mounted vertically, as angling the vent may cause it to shut off. Additionally, if you are using a remote rollover vent valve, ensure that the vent is mounted with the check ball in the bottom fitting.

Check the fuel pump regulator for obstructions

To check the fuel pump regulator for obstructions in your 2010 Kawasaki Teryx, you'll need to perform a few tests and inspections. Here's a step-by-step guide to help you through the process:

Step 1: Visual Inspection

Begin by conducting a visual inspection of the regulator. Look for any signs of fuel leaks, cracks, or other visible damage. If your fuel pressure regulator uses a vacuum line, also check for cracks or poor connections. Additionally, smell for gasoline in the vacuum line, as this could indicate a ruptured diaphragm inside the regulator.

Step 2: Test Fuel Pressure with Engine Running

Locate the test port, usually a Schrader valve on the fuel rail, and securely attach the fuel pressure gauge. With the engine idling, read the pressure on the gauge and compare it to the manufacturer's specifications, which you can find in your vehicle's service manual.

Step 3: Check for Vacuum Response

If your regulator uses a vacuum line, disconnect the vacuum hose and observe the gauge. The pressure should rise when the vacuum is removed. If there's no change, the regulator may be faulty. However, if fuel starts to drip from the regulator, it confirms a defective regulator.

Step 4: Perform a Key-On/Engine-Off Test

Turn the ignition key to the "on" position without starting the engine. This will activate the fuel pump and pressurize the system. Observe the pressure gauge; it should stabilize quickly at the specified level and hold steady pressure. If the pressure drops rapidly, it could indicate a leaking regulator or a check valve issue in the fuel pump.

Step 5: Test for Internal Diaphragm Leaks

Disconnect the vacuum line from the regulator and inspect the vacuum port for fuel. The presence of fuel indicates a ruptured diaphragm, which requires replacement. Optionally, you can attach a vacuum pump to the regulator's vacuum port and monitor the pressure gauge. If the pressure doesn't respond or leaks occur, the regulator is likely faulty.

Step 6: Conduct a Deadhead Pressure Test

For this test, carefully block the return fuel line using appropriate pliers or a fuel line clamp. Start the engine and monitor the pressure gauge. If the pressure significantly exceeds the manufacturer's specifications, it confirms that the pump is functioning correctly, and the regulator is likely the issue.

Additional Tips:

• It's important to work in a well-ventilated area and prioritize safety by keeping a fire extinguisher nearby.
• Always relieve fuel system pressure before disconnecting any components to prevent fuel spray.
• Wear safety gear, such as gloves and goggles, to protect yourself from fuel exposure.
• If your tests indicate a faulty regulator, select a replacement regulator compatible with your vehicle's make and model.
