iwas told that the injectors might have to go in a specific port like each one is specific for each cylider or can i just swap em one for one kinda deal.

do you use any fuel additive? That's my problem, everything in the systems are running correctly, but If I run just straight from the pump, doesn't matter if I just shut it off and 15 seconds later I need to run it, It won't start. I have to run some type of additive so much truck can burn it.

Make sure your getting BB coded injectors, you will thank me later .... those are the best HP ones you can get to my current knowledge, I have them and wouldnt dream of going back to the stock C codes....

truck blowing bueish white smoke at about 2000 rpm when in park what causes that any idea's. also fuel filter light on dash comes on when truck hits 2000 rpm while driving usually when it's in passing gear ( it's an automatic)

Air in fuel , if u have the fuel bowl at bottom of filter, change it out for a wix , use this number at a cross reference , BF1222 baldwin # ....

I had these same issues, I also havedone away withthe mechanical pump and gone to an electric fuel pump...
Your sucking air past the o ring. Now with a push type fuel pump, all you will see is a fuel leak, also check the actual return line Its self for leaks, as this will lower the fuel pressure and make the pulses from IP Weak .. keep posted..

Just keep in mind that when installing the electric pump to place it as close to the tanks as possible, will save you a headache in the future
