I never grinded mine out.... i just lubed them up with a little grease, and then bolted the fuel rail slowly and evenly... and they fit good and tight... never had a fuel leak.

 

jesus, I highly recommend grinding out the stock seals than just powering them in there. It's not that difficult to grind them out with a little dremel.

 

^agreed. It took us 10 minutes to grind out then install the seals on the 450's when we turboed my friends hatch. Easy work.

 

I ordered my rings as like the del sol vtec (don't know what model that is in the states) and my injectors fit in them fine, but the rings didnt fit the manifold so I just took them to the benchgrinder and did it up in like 5 minutes, fit nicely.

 

yes i agree with abaz, that is crazy ---- you didnt grind them out, i couldnt have even though about putting mine in without grinding them, you musta had to beat the fuel rail on with a hammer. :P

 

I just shoved my 450's a little and then went in fine(b18b)and I had 2 injectors with those plastics broken and I just took off the same plastic pieces from some grey tops I had and put them on the 450's.I hear some people say they are not needed but they wre put there for some reason so I just play it safe.
