What Happens If You Turbo a 5.3L Yukon With No Other Mods? PART 2: Fuel Injector Upgrade! (RIP 4L60)

What happens here

Before installing the new injectors, the existing fuel rail and old injectors are removed from the engine. The team then prepares the new Deatschwerks injectors by lubricating their O-rings with AMSOIL synthetic air tool oil. The injectors are carefully inserted into the fuel rail, ensuring the O-rings are properly seated to prevent fuel leaks.

Goal: Replace old fuel injectors with new 1500cc units.

Tools and materials

  • New Fuel Rail — A new fuel rail might be needed depending on injector type; otherwise, the old one is reused
  • Old Fuel Injectors — The existing injectors, which are being replaced
  • Old Fuel Rail — The existing fuel delivery system, which needs to be removed
  • Wrench Set — Removing and securing fuel rail bolts
  • AMSOIL Synthetic Air Tool Oil AMSOIL — Lubricating injector O-rings for smooth installation and proper sealing
