So injectors are currently getting re-popped to 325 and I've been watching youtube vids and write up on injector swaps. Obviously everyone does it a little different but I want to make sure I get things straight for my particular situation. As far as I know I'll be pulling on stock injectors and I don't know if/when a valve lash adjustment was done. 

 

When swapping injectors do I need to remove the exhaust rocker arms? Most videos show them being removed and I'm wondering since I don't think these injectors have ever been out of the truck if that'd be a good idea in order to verify the torque spec on the rear injector hold down bolt? 

 

I want to make sure I get the order correct when installing the new injectors. Seems it should..

 

-install injector with crossover tube hole facing towards crossover tube (lubing o-ring and washer with oil or vaseline)

-make sure injector is seated, should feel/hear slight pop once seated correctly

-install crossover tube, should feel/hear slight pop, verify crossover tube is sitting flush with head (lubing o-ring with oil or vaseline)

-tighten injector hold down plate (89inlbs for both???)

-again verify crossover tubes are seated and tube is flush with head

-installed fuel lines over crossover tube (25ftlbs???)

 

Anything else??

I've always took injection lines out completely in 2 sets of 3, they don't move much so I never tried leaving them in. 

Did you remove or loosen the (4) hold down bolts? Once you remove them the lines have a bit of travel

I never messed with blue clips, just took lines lose at pump and injectors 

I have attempted both ways (lines in place & lines removed). I had better luck with pulling the lines. Less fighting for me.

I tend to agree. Much easier with high-pressure lines removed. Still can be done with the high pressure lines in place. The only trick is to remove the 4 bolts hold the lines loosen all lines so the whole pack of 3 will flex. Then you get just enough room to pick out the crossover tubes. Just depends if you got times or not.

I have taken mine off both times I have done them.

I have never tried moving the lines.  I always take them completely off

I just pushed mine out if the way and held them back with a screwdriver or a piece of wood. Worked great.
