WHAT?
This is not accurate info.
The "pressurization bulb"??? Idle screw on the AFC???
Even after changing the fuel filter on a 12 V you rarely need to bleed air out of the injection lines. You usually can get a 12V started and the air will gradually work its way out of the system. I have changed many fuel filters on both 12Vs and 24vs over the last 8 years and Ive never had to bleed the lines at the injectors.
Corey,
First - from the fuel pressure numbers you gave - your fuel pressure is somewhat low. iirc, it should be 22 psi min at idle and increase to around 32-34 psi under full load. It looks to me like you might need a new lift pump. How many miles are on the stock pump? You do not need an electric pump fass or duramax. The oem lift pump will support 450+ hp.
Heres a how-to for lift pump replacement:

Again, how many miles are on the truck? You say you "turned the pump up" - meaning what??
You injector pump may have some wear. Its fairly normal to have to give it a little pedal to get it started. Bumping your idle up a bit may help (you should be @ 750+ rpm in gear with ac on). Heres how-to bump your base idle if you dont know how:

It might be worth changing your fuel filter and cleaning/checking the pre-filter. Heres a how-to on that:

Another possibility is that you may be losing prime from either dry rotted fuel lines (have the rubber lines ever been changed?) or from the fuel heater (this is a very common problem as well).
Good luck.

the 24v is max of 17
get your facts straight before spilling them
and as for the fass system it is a great addition to the truck or an airdog
