NBs' please help. What to do about fuel?!!?
I sell a clamp for $65. My email is in my profile.
The only problem you might have with fuel is a defective pump. You should really get a fuel pressure gauge wired in to watch it. I have several friends that have replaced pumps in their Mazdaspeeds with the same type system.

Thats what im running in my car..... the consensus with the 323 club is that they are infact 330cc and the red top GTR ones are 365cc.....
Having said that though, when i had mine cleaned and flow checked they flowed at 395cc at 3 bar,
so go figure!
i thought that the stuff they used must have been thinner than standard flow checking fluid or something.

I don't have, it runs fine, I don't think I need one. Mine's a little rough stransitioning into boost when not fully warmed up, but I always warm it up before driving so it's not a problem for me.
You said that you're running the Supra green top 310's? Do you think if you were to put the stock injectors back in your car as it sits now, you would be having the same problem as I am? And as far as the EMU goes, what other advantages than being able to run bigger injectors does it have over the EMB?
I had the same problem as you did, but I fixed that with careful tuning. As far as advantages of emu, I'm not too sure. Never looked that much into emb, but yeah bigger injectors, auto tune, maf elimination are things that come to mind.
You CAN use a FPR on a return less system. It has to be used in conjunction with an external fuel pump. But it does work.
My suggestion would be to upgrade injectors or use BEGi fuel system, and switch to the EMU.

Stephanie, that is very interesting. How do you plumb the FMU in a returnless system such as in the NB?
btw, this is how you plumb one:

basically it goes in it's own loop just before and after the inline....then when it starts to clamp off, some of the gas enters the fmu and gets clamped causing the inline to increase the pressure.

ahhh clever!
Scott, why don't you put that in your FAQ and then we can refer NB owners to it.

wonder if running 100psi fuel pressure into the FMU will have any negative effects. 
still pretty durn clever
