Injector replacement
I have an injector to replace planning on doing it in the morning I've been over in the tech folder reading on injector change. one thing it don't say anything about is sucking fuel and oil out of injector port. Is this a step that I need to do with the 6.0? I know on my 7.3 you had to do this step or you would hydrolock the motor and it wouldn't start. Also about how long should this take me with simple hand tools by myself?

Just suck the fuel out of rthe upper fuel bowel and thats good enough
The fuel rail will drain into the first inject you pull but its not that much especialy if you suck the upper fuel bowel out and what does go into the cylinder will drain to the crankcase by the time you go to fire it back up
just make shure you get an injector oring kit for each on you pull out
If it was me Id rering all 4 in that bank its cheap
I reringed all 8 cuz they wore out and would leak when cold
and just make shure the injector cup is clean upon reassembly and BLOW ALL injector hold down bolt holes out
IIRC I went to 26ft/lbs on injjector hold downs it was revised tourque spec from 24ft/lbs
tourque on these is VERY Important

If you suck the upper fuel bowel out it wont be that much
maybe 2 cups fuel MAX
you could drain it at the banjo bolts at the Heads to get most all of it but you should have a new gasket to go on it after its taken apart
Id run the oil for awhile maybe just change it alittle sooner
If you drain at the banjo bolt on the fuel rail at the head there wont be much fuel at all left to go down into the crank case I wouldnt worry about it if you did that

How long should it take me? Reason I ask the parts store don't open till 9 and close at 4 and it's an hour away and I've got to have old one out to take with me for core or pay the core charge that is out of sight HIGH.

I think the longest/most annoying part is getting the valve covers off, after that its smooth sailing...just be extremely careful and dont drop anything....
driverside is easier to do.
*make sure you get all of the oil or anything else that might have seeped into the hold down bolt hole to torque it properly*
its going to take some cranking to get it started and it will run rough and smoke until all the air is out....after that you should be good to go..
goodluck

03 just undo oil rail bolts then pull up till oil rail out of injectors and twist out of the way its on that HPO Stainless steal flex no need to undo it
its not to bad job
I reringed all 8 and spread it over 2 days taking my time
if I start racing threw it is when I break stuff or forget things
you need a long torx bit for the injector hold down
