Default lets talk fuel! 2003 and up

so my block go in next week to get built with all forged parts!!
i was wondering what options we have as 2003 Z06 owner's we have?

the few kit's i have seen all seem to offer a ext. secondary fuel pump to feed the fuel only when it's needed? if i am understanding that correctly?

also could i change out my fuel system to that of the pre 2003 setup? anyone ever done that?

you could run twin or even triple pumps in the tank or an external secondary pump run off a hobbs switch so whenever boost reaches that point the pump comes on, that's how I have mine setup... budget probably $2-3k to build a big fuel system if you get some nice injectors as well

Are you forced induction? if so a second pump operating on a hobbs switch (triggered with boost) is the way to go, either external or internal

No need to do that, plenty of fuel systems for post 2003, as that is what the C6's use. Just go to the vendors and look at their c6 fuel systems. Lots of options.

Whatever you do, avoid having a big pump running continuously as it will heat the fuel up.

For reference, my 2003 vert with 720rwhp has an ECS fuel system with a secondary external. You drill a hole in your tank and install a "sandwhich" plate (for lack of a better description) that has a feed port and a return port. Seems to work great.

I have 3 2003+ fuel system C5's. On my next one I'm planning to go E85 with dual internal pumps.
