After testing the set of replacement injectors on the car they were also leaking but not as badly (except one). I reinstalled them replacing the one that leaked the most with the one that didn't leak from the original 4.I think I'll just run with them as they are. The boost leak is very...

Oh boy, what a coincidence.. I happen to have a thread on a similar issue with my FIC 1200cc's https://www.dsmtuners.com/threads/leaking-boost-in-middle-of-fic-injector.543747Is yours leaking fuel from that seam? Because that would be different than my situation whereas I only have air/boost...

The FIC 1200 Hi-Z injectors straight from ECMLink website DO fit the stock fuel rail and injector wires (don't forget to delete the resistor pack). The electrical connectors connect up to the stock injector wires too. One thing to keep in mind, the connectors sit higher on the injector which...

Alright, I did some tests on the original 4 I had (not the warranty replacements in the car currently). Tested these outside of the car and CAN CONFIRM the leak is not through the body of the injector but rather through the plastic seam between the body and the exterior. Skip near the end of the...

Yeah, they had sent me a replacement set which is what is on the car right now. I haven't sent in the other set yet so maybe I'll just pick the best 4 and send back the worst 4.

Here's a video of the latest test last night.

Got the new Fuel system fully installed. -6AN from the sending unit to a new fuelab filter, -6AN from filter to a new FIC rail, -6AN from rail to new fuelab AFPR then to the oem return line (for now).Returned to testing the boost leak on the injectors now that they are sitting under a new Fuel...

Looking closer at the injectors height adapters and the seal for the top of the injector.. the seal doesn't get pressed between the hat/cup and tip of the injector. The tip of the injector protrudes past the seal so the only thing that could happen from additional mounting pressure is metal on...

I removed the injector height adapter cap (hat/cup) from one to have a look. The seal looks fine. Wondering if perhaps the issue would be the cup/hat not being fully compressed to the top of the injector by the clamping force of the fuel rail? Seems unlikely to have the same issue with 8/8...

I cleaned up the area where the injectors sit on the head, and cleaned where they connect to the rail. All the o-rings and seats look good with no wear or scratches. I've always lubed them with engine oil before installing.The bubbles still persist slowly from 10psi or higher intake pressure...

I'll pull them again tonight and try polishing the area with a scotch pad or something to be sure. A lot of the corroded look on my fuel rail and intake is the soapy water having dried to it. I haven't rinsed or wiped it away yet and it's leaving a crusty white corroded look to the aluminum when...

I jumped the fuel pump using the fuel pump test wire on the firewall and tested again. Super strange, I smell no fuel and see no fuel leaks after having the fuel pump run for a while. My fuel pressure regulator is working and compensating for pressure im adding to the intake. Did the soap test...

Had a thought, I'm not very confident in the readings on the gage on my fuel filter. Perhaps my fuel pressure is dropping lower than my air pressure during the test? I'm thinking it might be a more accurate test to jump my fuel pump relay so it's active. Then I can pump air pressure and the fuel...
