Bleeding the fuel lines?

I just put my stock injectors back in and am wondering if i need to bleed the air out of the fuel system? I never did this in the past, but just wondering if its bad not to...

Cycle the key a couple times to fill the fuel rail and fire it up.

Re: Bleeding the fuel lines?

any air in the fuel lines will either pass through the injector on start up or be forced back to the fuel tank through the return line

anytime a fuel line is disconnected, starting up is difficult immediately after, but after the vehicle starts up, it will start up everytime like it normally does

to speed up the starting process after disconnecting the fuel lines, prime the system by turning the key to the on position to turn on the fuel pump (automatically shuts off after 2 seconds). do this 2 or 3 times and then start the car
