How is an injector installed in a rail?
Injector fully seated into the rail. When the injector and adapter assembly is installed into the rail, it’s important that it’s seated fully in the rail without requiring additional force. If you have to draw the injector in with the cap, that means it’s not seated correctly and an O-ring is likely pinching.
Where are the FSI injectors located in the cylinder head?
6.1.1 FSi injectors are located in the cylinder head and fuel is supplied via a fuel rail which can be an intake manifold/ fuel rail assembly. Injectors can only be accessed after removal of the manifold/fuel rail assembly and therefore some disassembly and hose disconnections are required.
Where do you put the injector adapter in a car?
You can also install the adapter into the rail first and then install the injector into that, as long as it’s all lined up properly. As always, make sure to lubricate each and every O-ring, and I like to put a very very light smear around the inside of the fuel rail just to be safe.
What kind of socket do I need for fuel injectors?
A quick tap of a rubber mallet pops them right out. A deep-well 11mm socket is perfect for tapping injectors out from the bottom of the rail. Basically, the upper O-rings are the same size for both the new and old style fuel injectors for the 300ZX.

How do you replace the fuel injectors in a car?
How to Replace Fuel Injectors. The metal rod over the fuel injectors is the fuel rail. Use the socket and ratchet to remove the bolts and brackets holding the fuel rail in place. Depending on the model, some engines will need the fuel line disconnected from the fuel rail in order to move the rail.

How are fuel injectors attached to the intake manifold?
Set covers aside. Use pliers to disconnect the electrical connector on each injector. Lift the fuel rail off of the intake manifold, bringing the injectors with it. This takes a good amount of force, as the injectors are attached to the rail, and the sprayer tips are a snug fit in the intake manifold.
