Cleaning Your Fuel Injector in 6 Easy Steps: How to Effectively Clean Your Fuel Injector

Cleaning Fuel Injectors

After your car’s engine is shut down, gasoline vapor deposits left in the fuel injector can form a hard varnish. In time, this builds up and clogs the injector. In order to get the most out of your fuel injectors, you need to make sure to clean them periodically. According to some experts, fuel injectors should be cleaned every 25,000 to 30,000 miles in order for them to perform at peak efficiency. But, when it comes to cleaning a fuel injector, you don’t have a clue where to begin. That’s why we have all the information you need to know on how to effectively get the job done.

Using a Performance Fuel Injector

Before you begin thinking about cleaning your old, stock fuel injectors, we recommend you kick it up a notch with a set of hi-flow fuel injectors, like the Venom Fuel Injectors. Hi-flow fuel injectors maximize your fuel delivery and atomization and kick your horsepower and torque into overdrive. And, whether you’re looking for F150 fuel injectors or Dodge Ram performance fuel injectors, hi-flow fuel injectors are custom crafted for an OE-style fit.


Just like when choosing a new exhaust, a CAI or new filters, we recommend you always stick with the brand names you can trust in order to get the best performance possible. Check out the customer reviews on our website to see just what our customers have to say about the BBK Fuel Pressure Regulator or to find the latest Fitch Fuel Catalyst review. You can even search the reviews for other vehicle-specific performance 1990 Ford Ranger parts, like mufflers or exhaust systems.

How to Clean Your Fuel Injector in 6 Easy Steps

Once you decide on new fuel injectors, all you need to know is how to clean a fuel injector in order to keep it performing its best. All you need is a long screwdriver and a fuel injector cleaning kit that you can pick up at an auto supply store. You’ll want to follow the directions that come with your cleaning kit, but the following instructions can give you an idea of how to get the job done.


Step 1. Disable the fuel pump and plug the fuel return line or install a U-tube so the fuel will return directly to the tank.


Step 2. Disconnect the pressure regulator and connect the cleaning kit to the fuel port on the fuel rail.


Step 3. Remove the fuel cap from the gas tank. Then, turn the ignition to ensure that the engine will not turn over.


Step 4. Open the valve on the kit until the fuel pressure reading matches the one for your vehicle.


Step 5. Start the engine to run the cleaning solvent through the injectors and let it run for about five minutes until the engine shuts down.


Step 6. Reset the fuel-pump switch and replace the gas cap. Reconnect the pressure regulator and then start the engine. Check the fuel injectors for proper operation using your long screwdriver as a “stethoscope.”
