Fuel Injector LH

When reusing the fuel injector
1. Replace fuel injector seal, decoupling, support disc and O-ring with new parts. Ref. to FUEL INJECTION (FUEL SYSTEMS) (H4DOTC)>FUEL INJECTOR>REPLACEMENT .
Set the holder to the fuel injector assembly, and install it straight to the fuel injector pipe LH.
CAUTION:
- Always use a new holder.
- Degrease inside of the fuel injector insertion hole of the fuel injector pipe.
- Check the inside of the fuel injector insertion hole of the fuel injector pipe for foreign materials or damage.
- Be careful not to allow gasoline to contact with the fuel injector seal and the inside of the mounting hole.
- Apply liquid paraffin to the O-ring and install it.
- Be careful not to twist the O-ring.
- To prevent damage to the O-ring, insert the part straight along the fuel injector insertion axis without tilting it and avoid removing and inserting the part again.
- To prevent the tip of the fuel injector from bending, do not apply force to the fuel injector tip.
- Check that the tip of the fuel injector has no bend or damage.
- Make sure there is no gap between the fuel injector pipe and the fuel injector holder.
- Make sure there is no gap between the fuel injector and the fuel injector holder.
