Depends on what setup you run. Is this on and Eaton, Whipple, KB? There are a million ways to do it just depending how much fuel for what setup you need.
Looks good so far.. you'll also need either a modified FPDM or dual setup, and wiring upgrade to battery
Yeah. Hit up black302 for a modified fpdm or dual setup. He made me a wire harness w relay for my dual setup so i could drill and modify the stock hat with a pair of 12ga wires (for each pump)
My tuner stared me away from the GT pumps and a BAP. He is a very well known tuner and informed me the drivability sucks real bad with the BAP and GT pumps. So save your money and build a quality return system and do it once.
The returnless setup can work, but by the time you spend all the money on what's needed, you can just buy a return setup and be done. I sell a lot of Fore L1E kits with (2) 465 pumps. Works great and will provide plenty of fuel with the proper injector.
