i know there have been other threads and they say the injector just set on top of the manifold o ring then just tighten down

here is a pic the red arrow shows there the injector hits the hole in the manifold


is this deep enough into the manifold?




the second knotch going from the bottom is where it hits the manifold

 

Are the fuel rail spacers installed in the pic? I would remove them to let the rail sit further down, take a Dremel and enlarge the lower seals if they need to be.

 

the studs broke a while back so i just just bolts instead... but the injector where the arrow is hits the hole for the injector so only the first knotch and nozzle are in the hole

if i enlarge the manifold rings so the injectors goes in it still wont go to the the lip thats under the writing

 

Seems like your only choice is to let them sit on top. If you have leaks/problems look into injectors that actually fit correctly.
My RC's fit all the way down, but I never used a y8 manifold when I had a SOHC. I had a skunk 2 mani, not sure what the difference is though...

 

rc makes injectors for B,D,F,H and another size for k series engines.
do they fit in the fuel rail?

 

can you post pic of your RC next to your stock?

 

when i get home from work, i can take a pic of the 2 side by side, both sizes of rc440s.
i don't have an intake manifold handy...
the k-series size injector tops are too big to fit in regular fuel rail.

 

it looks like your missing the stock Oring
that should be in the manifold then the injectors sit nice n sealed

 

i think he left the o-ring off so you can see where the injector hits the manifold.

 

this

also these are SL9 440's which are suppost to fit the d series

yes they fit on the fuel rail just fine

 

I forgot about Y8's having the long shouldered stud mounted fuel rail...You need to replace those! Using bolts will not hold the fuel rail straight and at the proper height.

Also... Is there another little lip inside the manifold, besides the first lip for the grommet?

 

stock OBD1 on the left, D,B,F,H series in the middle, K series on the right.
