ok, I had the blue top 450cc, but they were off an 89 turbo gallant and I think they were worn out and one was stuck open, so my friend gave me a newer set of american black top 450cc and I can't get then into my fuel rail. if I take off the top O-ring, they will fit in, but I can't shove them in at all, they look about the same size as my orignials...

 

My black tops slid in...took quite a bit of spit but i got that ****** on

 

Hahahaha.. that's a totally gross image. :P

 

oh, you meant sliding it into the fuel rail...my bad :P

 

yeah, they fit into my manifold, but not the fuel rail, I don't get it!

 

u cant drill the holes bigger or something?
or better yet use ur honda o-rings or the galant ones

 

what i did is got a new set of o-rings from honda for my car and it works fine...(i have the black tops too)

 

Sounds like they are the wrong injectors. Whats the part number on the side?

 

It's the O-rings that's the problem. I put the 450 o-rings on my stock one and THEY won't even fit in. I had the gallant ones and they fit fine, but the o-rings are all worn out, so I'll go buy some new ones. thanks for the help.

 

use the honda orings they are a tad smaller, Be sure to use a little bit of grease, lube or anything on the rings so they slide into place.
