[QUOTE="SnakeBoostE85, post: 16762487, member: 160175"] yes - return style... base pressure is about 39 psi, idle or key on. Pressure rises perfectly with boost with the boost reference going to the regulator. At WOT, in boost it immediately goes to 55-60 psi... all seems good there. Honestly I think I let it sit too long and its all gummed up... just gonna have to take it all apart. Service injectors, clean everything and possibly replace the pump and filter... I'd feel better just putting a new pump in. I overheated a few times before I installed a fuel cooler. Which is a whole other topic of discussion with these return fuel systems. [/QUOTE]
