What to do next?

If it's such a good design why the need for a long lead injector on #8 from the factory?

Yep LOL

How does feeding it from all four corners eliminate the dead head? If fuel is going in all four corners, the only way for the fuel to get out is to go through the injectors, exactly the same way as a stock fuel system. On a regulated return, the fuel goes in one end of the head and comes out the other end.

HA!! This made me think of two days ago, getting new tires and an alignment on my sons truck. The tire guy said he was looking for an '01-'02 7.3 because those were the only years that had HPOP's on them. He had no idea that HPOP's run the injectors. He thought they just lubricated the motor better. :wtf:

He actually said "bull****" when I informed him of how they work and that any 7.3 or 6.0 has an HPOP.
Sorry for the derail.

New to the forums and have a question for you guys. I recently bought a 2002 F350 CCSB from a buddy. It ran perfectly fine before I cracked into it with the upgrades. My question is what else do you guys think I should do to the engine/drivetrain to make it the most reliable I can? So far I have done: CNC 4 line fuel kit, rebuilt fuel bowl, MB diesel HPOP, new IPR sensor, HPX, CNC HPOP lines, 38R, WW2 6/6 wheel, hydra, S&B intake filter, BD diesel bellowed up pipes, 4" downpipe, high flow turbo outlet, AIH ******, EBPV ******d pedestal, replaced CCV doghouse Orings, oil fill tube Oring, and just have a JWVB to install still. Is there anything else I could do? Plan on getting a 6.0 trans cooler soon and injectors and JW trans after deployment. Thanks for your help

What power level are you looking for and how many miles on the truck? I'm going through this with a 2001 F350 w/ 319,000 miles on it. You can check out the thread here. I'm currently talking to tuners about injectors. Probably going to stay pretty minimal on them for reliability.
You've done quite a bit already, but have you looked at maintenance item like u-joints, carrier bearing, ball joints?

I have never understood the 4 line feed kit either. Mainly because I am not sure how any air would escape from the fuel rail without going through the injector. From the pictures on the link posted, I see no return lines coming from any port on the head. This kit may eliminate fuel starvation, but it definitely will not eliminate any air in the system.

Maybe someone can explain it better, or inform me of something that I do not see on the picture?

return line on the fuel bowl is on top for a reason...

Yep, still a dead head system. Deadhead from four corners instead of two.

still deadheads yes, but like tim said, most bone stock 7.3 injectors last well above 200k miles.. by rights, any air in the stock fuel bowl should exit up top before it gets pushed out the botom of the bowl... only way to really get air in the system is by running out of fuel or any way your fuel is foamy..
