Product Details and Specifications

The Standard Ignition FJ728 fuel injector is specifically designed for multi-point fuel injection (MFI) systems, commonly found in Lexus and Toyota vehicles such as the 4Runner, GX470, Land Cruiser, LX470, Sequoia, and Tundra. This fuel injector features a plug-in attachment method, making it easier to replace without extensive modifications. The black finish and relocated inlet filter near the injector body help optimize fuel flow and filtration. It is a top feed injector with two male blade terminals, ensuring compatibility with the vehicle’s electrical system. The package includes necessary gaskets and O-rings to maintain a secure and leak-free seal, although retainer clips and additional hardware are not included.

Compatible Vehicles and Common Applications

This fuel injector is compatible with the following Lexus and Toyota models equipped with MFI fuel injection systems:

  • Lexus 4Runner
  • Lexus GX470
  • Lexus Land Cruiser
  • Lexus LX470
  • Toyota Sequoia
  • Toyota Tundra

It is designed to address issues such as:

  • Engine misfires caused by faulty fuel injectors
  • Reduced fuel efficiency due to inconsistent fuel delivery
  • Rough idling or hesitation during acceleration
  • Fuel leaks from worn seals or gaskets
  • Injector clogging or poor spray pattern

Installation Notes and Tips

When installing the Standard Ignition FJ728 fuel injector, ensure the vehicle’s ignition is off and fuel pressure is relieved before removal. The plug-in attachment method simplifies the replacement process, but care should be taken to avoid damaging the male blade terminals. Replace all included gaskets and O-rings to prevent leaks. Since retainer clips and additional hardware are not included, reuse existing clips if they are in good condition or source replacements separately. Properly seat the injector to maintain the top feed system integrity.

Quality Assurance and Warranty

Standard Ignition provides this fuel injector as a new component, manufactured to meet or exceed OEM specifications. The inclusion of gaskets and O-rings supports a reliable seal and long service life. While specific warranty details may vary, Standard Ignition parts typically come with a limited warranty against defects in materials and workmanship.
