Fuel rail install

Take your fuel injectors and the fuel rail.

then just squeeze the injectors into the rail making sure not to pinch the O-rings or you will have a gas leak
will be hard to do.

After they're in the rail, just insert it onto the intake manifold and lightly hammer down with a rubber mallet making sure not the pinch the other O-ring as well.

The fuel injectors and rail have just been installed, simple, the rail is built by 034 for the 20v head of the Audi Inline 5 motor.
