Okay so I installed my dsm blue top 450cc injectors in my h22a4. I shaved inside of rubber gromets down so they poped right in. On the top where they attach to the fuel rail..they go into the fuel rail i think but the fuel rail doesnt go down as far on them as they did the oem honda ones. I think this is okay? I dont know though.....as long as they are just in the fuel rail past that rubber seal at the top its fine right?

 

As long as they don tleak youre fine. You may have to put everything together and find out. When I put my 460's on last weekend I had to shove them in the rail, once past the O-ring they were ok. After putting everything together one leaked, turned out I broke an o-ring.
Good luck

 

oooh okay....sweet yeah ive seen some scary pictures of some so i figured i did it right so we will see...

 

yea just put the whole thing togther and see if it leaks. to make it easyer put a little oil or water or something on the o rings to lub them up and it will make it and easyer install. i did that and they went in easyer..
