From what I read, if and when I use the Bell RRFPR I still need my factory fuel pressure regulator, or at least some other FPR. You guys with billet rails, what are you using in conjunction with the bell unit and where is the main FPR location on your set up?
Also my recon'd turbo injectors have about 4" of EFI hose on them, what should I trim that back to before I slip them on the barbed fittings in the billet rail.
Thanks
