Is it hard starting ??
Does it die after it starts ??
Does it clear up after a few minutes ??
FYI, Bleeding is done at the Schrader valve on the Filter head, it is unnecessary to crack injector lines, once the air is out of the system up to and including filter, the Injection pump will bleed itself in just a few revolutions of the motor.

Injector Return Kit Installation.
Injector Installation Kit
Many prefer to toss the o-rings in the kit (and I highly suggest you do) and use these Viton Return O-Rings - McMaster-Carr Item 9464K24, Viton is impervious to Diesel.
For the Injector Installation Kit installation You can follow Starmilts Humorous Fuel Return Replacement Procedure, I like to cut the 6 pieces between the Injectors to 4-1/16", Use a sharp razor blade to cut the hose and Vaseline to lubricate the o-rings.
For proper fuel system bleeding you can use steps 1 through 4 and 13 through 15 of the Fuel Filter Replacement.
