Cp3: which port is what

[Veikra]

im chasing a no start after doing my headgaskets. Truck was running perfect before the job.

3 port, one is obviously high pressure. I want to know which is in from fuel filter and which is the relief . I can't see anymore since engine is back together

Maybe my cp3 fpr got stuck? Looks like im not building pressure

The nipple face upwards, towards the hood is return, the one face towards the rear of the engine is supply

Harbin is correct. The one next to the high pressure is the return. On the back by the reg is the feed.
