I'm running an in-tank pump module from a VE/VF Holden Commodore, which is basically a ZL1, but the pump is slightly smaller. My module has a regulator built into it but when I powered the pump @ 100% DC, it gave me 80-85psi of line pressure. When I found that model of car uses a CANBUS fuel pump controller, that is when I sourced a Jaguar unit which works perfectly with the Megasquirt 3X. As mentioned on another page, the same fuel system design will be going into my in-tank fuel cell setup but with a staged secondary pump for E85. I'm a big fan of running a controller on pumps now! Mine is whisper quiet, you can't even hear it prime.
