Need urgent help with fuel injector install!

[J.DeFeo]

I've got the old injectors out, but the new ones won't go into the fuel rail. They slide easily into the cylinder but they won't budge when I try to push them into the rail itself. The o-rings are new and lubricated. They are the correct size. Any idea? M30B35, 535i.

EDIT: Nevermind! I'm retarded. Put the wrong size orings on each end of the inject. Flipped them around and now it fits perfectly.
