Quick Injector Question
#1
The picture below is of my primary injectors. There are two rubber seals on each injector, an o-ring at the very top and another seal right above the red electric connector. On my secondary injectors there is also a seal at the very bottom, on the green part where the fuel comes out. Are they supposed to be different like this or did someone leave the seals off the bottom of my primary injectors?

you have the "o" ring that seals the injector in the fuel rail then a grommet-type that holds the injector in place that goes on top of the injector. Then a washer type that goes around the nozzle of the injector to seal the intake and such.
the upper ones are prone to failure under boost because the pressure tries to push the injector out of the intake, the o ring HAS to be changed everytime the injectors are removed from the fuel rail. And I believe the bottom ones can be reused to an extent because they are thicker and simple.
and it's the same for all four
