SARD 550cc injectors dont sit right

[handinpants]

hey I bought the 550cc injectors, model: 63508 for my s13 sr20det. i went to install them into the fuel rail, and even with the collar on it it doesn't look right. the sard injector looks longer than the nismo one. is this correct?
anyone had this problem? and what was your solution?

You might have the long type. Which should work though. I have those in my s14. Is there a gap?

[Erjay1]

yup thats what Ive got. Those might be for an s14 sr20. I believe your fuel rail is different than mine. Yours mounts up over the intake manifold right? See, mine mounts below the intake manifold which is probably why I can fit the long type like those Sard's.

HAave you checked that there are no o-rings stuck inside the rail?

its a brand new rail... there ain't no o rings in it.... this is retarded... i bought them from this company in japan...
