i got some 440s rc's for my y8 i took everything off got them in the fuel rail sitting nice but the 2 bolts that hold down the fuel rail then you put the nuts on i tightened it fairly tight but my injectors are still really loose in there? What should i do about this to make them seal against the holes and the fuel rail? Thank you.

turn it to the on switch. if it doesnt leak, it should be ok.
i tighten mines with an str rail, mines... i could rotate them just a bit, but doesnt leak at all

i have like a quarter of a cm left inbetween could i just use my grommets from my stock injectors and these injectors and make a double stacker.

or just get the INJECTOR SEAL KIT from your local auto parts store and make them fit nice and flush. Also check this out, its for the DSM’s but you'll get the idea.

i guess they just sit like that cuz i installed them and put in my ecu i did what you said and put the car in the on position a few times took off the banjo bolt thing fuel sprayed everywhere so i kno i had fuel pressure thanks for the help. it smells really rich with my base map and my idles goes up and down like it did with my stock injectors. maybe i can fix this when i get my wideband put in. thanks for the help guys.
