Removal the fuel rail and injectors (Chevrolet Lanos T150)

We remove the fuel rail to check the operation of the injectors and replace them, as well as to remove the fuel pressure regulator and intake manifold.

We release the pressure in the fuel system (see Replacing the fuel filter).

To remove the tip of the injection line tube from the fuel rail fitting, you must use a special tool.



Its working parts 1 allow to release (unclamp) the metal spring holders of the tip of the discharge line tube.

In the absence of a special tool, we make a device from a piece of metal or plastic tube with an internal diameter of 8.0–8.5 mm and an external diameter of 11.5–12.2 mm.

We cut the tube lengthwise into two halves.



For example, you can make a device from a metal wheel valve cap by sawing off the spout and cutting it in half.





Or, for example, here is a device made from a piece of pipe of a suitable diameter.



We put the halves of the device on the fuel rail fitting and insert them into the tip of the fuel pipe.



Using the jaws of the pliers, push the device into the tip of the tube..



…and remove the tube tip from the fuel rail fitting.





By lifting the injector wiring harness connector retainer..



…we remove the block from the injector.

Similarly, we disconnect the engine management system wiring harness connectors from the other injectors.



We remove the hose from the fuel pressure regulator fitting.



We squeeze the petals of the drain line tube tip retainer and remove the tube tip from the regulator branch pipe.





Using a 12 mm socket, unscrew the two bolts securing the fuel rail to the intake manifold.



Pulling the fuel rail along the axes of the injectors, we remove the rail, removing the injectors from the holes of the intake manifold.

To remove the fuel injector…



…we pry the retainer with a slotted screwdriver…





…and we take it off.



We remove the injector tip from the fuel rail hole.

We remove the top…



…and the lower rubber sealing rings from the injector tips.



We remove the remaining injectors in the same way.



We replace the injector sealing rings with new ones.

Before installing the injectors into the ramp and intake manifold, apply a thin layer of engine oil to the sealing rings.

Assembly and installation of the fuel rail with injectors is carried out in the reverse order.
