Poor Fuel Filtration

 

 

 

 

Problem: Ball seat erosion

A proper seal is critical for injector performance. Abrasive contaminants can erode and damage the ball seat causing the ball not to seal properly leading to improper injection.

Solution: Use OE filters or filters having the same OE micron rating and follow the recommended OE filter change interval. Using anything less can cost you more in the long run!

Causes:

  • Inadequate filtration
  • Poor quality fuel supply
  • Inadequate maintenance intervals

Effects:

  • Starting problems
  • Poor performance
  • Idling problems (vibration)

 

 

 

Fuel Contamination

 

 

 

 

Problem: Fuel Contamination

How does the water get into the fuel? A vented cap allows air to enter the storage tank to equalize pressure as the fuel flows out. The outside air contains moisture and this moisture condenses into water inside the tank.

Solution: Always purchase fuel from a reputable service provider and use a proper fuel/water separator.

Causes:

  • Water in fuel
  • Poor quality fuel supply
  • Inadequate filtration, water separation
  • Inadequate maintenance interval

Effects:

  • Poor performance
  • Idling problems (vibration)

 

 

 

Incorrect Installation

 

 

 

 

Problem: Incorrect installation can include: missing sealing rings, incorrect tightening torque and incorrect cleaning of the nozzle. This causes poor performance, misfiring, black smoke and check engine light (MIL) to come on.

Solution: Always follow the engine manufacturer’s maintenance procedures.

Causes:

  • Missing sealing ring
  • Incorrect procedure and/or tightening torque when installed
  • Inadequate filtration, water separation
  • Inadequate maintenance interval

 

 

Effects:

  • Black smoke
  • Poor performance

 

 


 

 

 

 

 

Causes:

  • Incorrect Tightening Torque

 

 

Effects:

  • Misfire
  • Check Engine Light (MIL)

Non-OE Quality Part

 

 

 

 

Problem: The purchase of any non-OE quality part. Using a non OE quality part can result in poor fuel mileage, poor performance, misfiring, black smoke and no starts.

Solution: Make sure your vehicle is being serviced by a reputable shop and ensure they are using parts are from an OEM approved supplier. You’ll receive the same OE performance, reliability and durability as what your vehicle was originally equipped with.
