Also, plug all orfices in the fuel rails with scraps of rag to prevent any metal polish residue from entering the rail.

Another tip to make your install easier...cut some "U" shaped shims out of sheet aluminium (available @ most hardware/hobby stores) about an inch square, with a 1/4" slot in the middle to aid in alignment of the fuel rails.
On mine, the rails were slightly mis-aligned when tightened onto the existing (on the Alpine manifold) mounts causing some binding issues with the injectors. When the rails are tightened to the mounting lugs, you should still be able to rotate the injectors back & forth with moderate hand pressure.

Use emery cloth to slightly enlarge the beveled edge where the injectors go into the fuel rail & ample silicone grease on the upper & lower injector O-rings to keep from tearing O rings, as clearances are VERY tight.

Good Luck !
