Fuel injector maintenance and the service of its related components is as important as maintaining any other part of the vehicle. A clean fuel injection systems will ensure engine reliability, longevity and proper performance.

With emissions testing and the enforcement thereof becoming increasingly stricter it has become very important to ensure that the fuel injection system and fuel injectors, are clean and operate as designed. Failing an emissions test on your vehicle can be very costly. Although we recommend to always use quality brand names when filling your tank with fuel, it is not always possible and therefore it is recommended that a quality injection system cleaner should be used.

The addition of ethanol to our fuels are causing major problems and care has to be taken to ensure a good quality fuel stabilizer to be used when storing a vehicle or any gasoline based equipment for extended periods of time.

Marine Fuel Injection Systems

Gasoline based fuel systems used in the marine or watercraft industry, suffer from the same fate than that of their brethren on land. Due to its nature, the presence of moisture is more prevalent on the water than on land, combined that with the use of ethanol in our fuels and the problems the boating and watercraft community face is huge.

Dirty and clogged marine injectors have cost their owners thousands of dollars in engine repairs. If your application don’t want to perform under wide open throttle pull the throttle back until the engine runs smooth or to the point where the engine maintains a steady rpm.

Fuel injection cleaner and stabilizers.

The use of good fuel stabilizers and injection cleaning additives is not always successful. Many times the boat captain or pilot find him or herself in a situation where the engines do not deliver enough power when they need it the most. Within a blink of an eye the engines will go from running smooth to having just about no power at all. In most cases the problem can be and has been traced to the injectors.

We suggest and recommend that boat and other watercraft owners have their injectors cleaned every six months or at least before the start of every season. The cost of cleaning a set of injectors is far less than having  your watercraft towed to shore or rebuilding an engine.


Clean Injectors ensure proper engine performance

Injector Cleaning

  • Although not complicated the cleaning of dirty fuel injectors or fuel injection systems has to be done properly. Understand the possible consequences and know the correct procedures before you pour cleaning additives in your tank. Not knowing what the product can and will do can have disastrous consequences.
  • Theses cleaners can not differentiate between the various fuel related components. It will have a cleaning affect on all the components it touches, thereby sending all the removed debris and contaminates from these  components  directly to the injectors. This can cause the  filter baskets to become clogged. The minimum you can do before you use any in-tank cleaner on an older vehicle or a vehicle with suspected fuel related problems, is to ensure drain the old fuel and install a new fuel filter before you pour any cleaner in the tank.
  • Take into consideration that some in tank fuel injection cleaner and the overuse of  these chemicals can and eventually will damage expensive catalytic convertors and possibly oxygen sensors too.
  • If the vehicle was not operated for an extended period of time we suggest that all fuel related components be cleaned internally before additives are poured into the tank.
  • Never clean clogged fuel injectors with carburetor cleaner because the carburetor cleaner can and will damage filter baskets and other sensitive parts.
  • Never try and clean your dirty or clogged fuel injectors by blowing high pressure compressed air or aerosol cleaners such as brake cleaner etc. directly into them because it will cause damage to the filter baskets and cause debris to get stuck between the pintle valve and housing, causing the pintle valve to become stuck.
  • Always handle your injectors with the utmost care and never drop them because it can cause internal damage, damage to the pintel caps and on some injectors it can even cause the pintle valve tips to get damaged or break off.
  • Use a vacuum cleaner to remove any dirt from the area where the injectors are installed at the base of the intake manifold or cylinder head.
  • Do not re-install your cleaned injectors with old, hard and cracked o-rings and make sure there is a proper seal between the  injector and the fuel rail as well as between the injector and the intake manifold. If you do not have O-ring grease, use clean engine oil or Vaseline.
  • To prevent damage to the engine control module, always use injectors with the same resistance than that specified for the use with your engine’s control module.
  • If you are going to store your injectors for any length of time it is good practice to make sure that they are clean, well lubricated and stored in a sealed plastic bag. Try to remove as much air from the bag as possible.
  • Most of those who attempt DIY fuel cleaning spend more money and time on the cleaning process than what it would have cost to sent the them off and have it professionally cleaned. In the end that is what most do after they tried to clean there own dirty fuel injectors, send them off and have them professionally cleaned.
  • What ever you loosen in the tank or in the fuel lines has only one way to go if the fuel filter is not in good shape, straight into the injectors. Any thing after the  filter will automatically be sent to the injectors causing them to become  partially or completely clogged.
