I'm having leaks through the injectors id1050x. I believe its maybe the o rings. But I was looking at how the id1000s were installed with stock cushions and an added washer. Just wondering if I need to that with the id1050x. It's also on a Aem fuel rail

 

They should come with an aluminum o'ring base. The o'ring seals against the intake manifold and the lower injector o'ring seals the injector from the aluminum insert.

 

So it needs no cushion or additional o ring from the oem injector? Ima swap out the top o ring that goes into fuel rail hopefully that stops leak. Thanks bro

 

All ID injectors are shipped this way for AP1 fitments now. You do not reuse any stock seals or cushions.

If you are getting a leak at the top and the o-ring is completely seated in the rail you either have a bad o-ring or you have the rail/injector cocked.

 

Taking a second look. It looks like it's coming from bottom of injectors, on intake manifold. I tried tightening the nut on the fuel rail stud. But it keeps spinning and not tightening.

 

If the rail isn't being secured, that is definitely a problem.

 

Looks like the car will be down until I prolly replace studs nuts and o ring. Hopefully no more leaks after. Also gonna switch to ss lines for fuel pressure regulator
