You'll be on a Red right? I would try with the stock hard lines man, and if it you are having issues, then upgrade. But I think you'll get by fine with the hard lines. Just have to make sure that banjo area is decent enough with that gauge on there
well unfortunately my FPR gauge sits on top of the fuel filter, it replaces the stock banjo bolt, don't know how I'd get around that, inline pressure gauge?
Again, it may not be IDEAL to do it, but you can, and I will be simply for the sake of simplicty. I want to keep things simple. That banjo fitting on the stock filter to rail feedline is a restriction, that's the reasoning to upgrade that line
