Hey guys, new to the forum here just looking for a bit of help installing the Tomei type s fuel pressure regulator.
I can barely find any info on how the OEM FPR is setup, and the instructions are a little confusing since they're universal.
I've attached the install PDF and I'll try to get some engine bay photos later as I'm still at work. (There's also a fuel rail adapter mentioned which I've purchased as well)
Running a pretty stock VQ35DE '03 350Z.

Thanks in advance for any help!

Can you help us understand the details of your car? If you're running a mostly stock DE, I don't see the necessity of running this FPR at all. Are you boosted with upgraded fuel and/or a fuel return system?

Going for a twin turbo build around 400WHP, trying to eliminate potential bottlenecks first so getting fuel system out of the way first.
Still waiting on my fuel pump to arrive and gonna replace the intake plenum before I put the new injectors in so that's where I'm at now.
Fuel pump is a Walbro 460LPH and injectors are secondhand 550cc from an R35

I'd go ahead and bump up to something closer to 1000cc's just to give yourself some head room. Would go ahead and get a fuel return system as well

would you recommend getting both of those first before doing the FPR and fuel pump?

To me, I'd probably do it all in one go.

I've never really enjoyed working on a fuel system, so I did it all at once vs piecing things together since most of the parts work together better.

So, fuel pump, fuel rails, FPR, injectors, and fuel return. Leaving one out will eventually end up being the bottleneck.

At 400whp, all you'd really need is some injectors and a fuel pump.

If you plan to go higher later, just do it all.
