Here's a quick note to help with installation:

When you install the injectors tighten slightly the injector hold downs (retainers) FIRST to about 15lb-ft. Then tighten the injector line (19mm nut) in the head to about the same low value.

Then go back and tighten the retainers to full torque spec, then finally the 19mm injector line nuts.

This will ensure that the high pressure connector (the crossover tube that goes into the body) will seat properly in the injector chamfer and not leak.

Don't over tq the 19mm nuts or it will leak. Don't over tq the little 8mm retainer capscrews or they will break.
