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.
