[QUOTE="01yellercobra, post: 15639077, member: 35549"] My understanding is it's a mix of the two. There's a mechanical limit in the tank. I want to say around 50psi. But the ECU still modulates the pumps in the lower end of things. Which is something that's good about the returnless. At least in the newer systems. The pressure can be dropped at idle and part throttle to better control larger injectors. I don't know if the 03/04 ECU's can do that. [/QUOTE]
