Bear with me. I'm new to these motors and have chosen to put an L98 crate motor (aussie one) in my Z32 300zx.

Basically, I am used to seeing fuel rails that return to the tank but this motor doesn't have a return on the rail so i'm confused how you hook up an adjustable FPR to it? Do you need to change the fuel rails to aftermarket to accommodate a return line ?

I already have a return line on the car itself so it won't be a big deal if i need to change rails.

Thanks in advance.

Im pretty sure you do. Not 100% though. I went ahead and changed mine when I added my FPR. I would go ahead and do it anyway just because it would perform a little better.
