NOT E
After assembling fuel injector, always check area between nut and body. If preformed
packing is still visible after nut is torqued, try another nut and preformed packing.
Using injector wrench (11), torque injector nut (1) to 75-85 Ib-ft (102-115 N-m) for blued
components, 45-55 Ib-ft (61-75 N-m) for steel gray components, or 60-70 Ib-ft (81-95 N-m) for
mixed components.
