Not sure. I think the chances of it splitting and if not noticed spraying nice flamable fuel over the engine highly likely. Might not be a good idea???
Ive read this in a Haynes Engine Management book. The flow is not restricted. It is the same theory as replacing the spring for one with more tension that simply ups the pressure. What pressure this is going to be is anyones guess.
The valve has a spring that allows the feul to run back to the tank when a predertermined pressure is reached, say 3bar. The vacuum further opens this valve when idling etc so as to lower pressure.

The line goes to the inlet manifold to control the pressure an whatever boost you're at.
If you're at 1.3 bar the fuel press is raised by 1.3 bar ie to 4.8 bar.
Squashing it is not a good idea I'd say they're weak enough already. And yes, it will restrict flow. Restricting flow is how it controls pressure in the first place!
FPR is on the outlet of the fuel rail and is just a regulating valve. by shutting off the valve and hence reducing the flow to the tank return, the pressure rises.
What power are you after and what injectors/ fuel pump do you want to run.
You may find that upping the pressure isn't needed.

its a my 00 so its got 440 injecters, ive got walbro pump,uprated turbo with supporting mods to get around 330bhp, its also got a parallel fuel rail mod using the standard regulater. do you think it will be ok?
if its definatly needed i will have to get one, im just skint at the mo and my remap is on the 24th. is any one else using a standard reg with this sort of power? thanks
RB5: Wasn't/isn't quite clear whether you're suggesting he run a 'squashed' FPR or run the std one until next month - hopefully the latter
I would rather postpone the mapping until everything is in place as you (presumably) wouldn't be able to realise the benefits of increasing the FP if mapped with OE FPR.
he has 440's, which will be bine for 330bhp on stock fuel pressure
