Rb25de fuel rail regulator

[Prof_Finesser]

On the r32 gts25 the fuel rail has 2 regulators can the rear reg be deleted and also make the fuel rail returnless?

[Dose Pipe Sutututu]

it's not a 2nd regulator, it's a fuel pulsation damper 

And why would you want to make it a returnless system?

[GTSBoy]

And no, you cannot make it returnless. You still need a reg, and in a returnless system, this is at the fuel pump, in the tank.

You cannot remove the reg. You need a reg. If you remove it, you will need too remote mount it or a replacement.

You cannot remove the pulsation dampener. It wont run nicely without it. If you remove it, you will need to remote mount it (and it wont work as well as it should when remote mounted.

Revert FFP to stock, or go full aftermarket rail and reg. No halfway measures.

Probably buy the radium rail then cuz it’s not ffp it’s a whole ffi from speedtekauto

Just go buy a Plazmaman billet series plenum, convert to DBW, piss off the Nissan OEM tps sensor, IAVC, AAC, at the same time.

Win.

So it's a  Freddy. Are you sure it fits? These things (the Freddies) kinda have a history of sucking. Literally. Through the flange gaps.

[Ben C34]

Car will run with no reg and a tune if you really want to.

[Prof_Finesser]

Its a real mani and it fits really well Im going to just buy the radium rail and damper

[GTSBoy]

Has it run without demonstrated vacuum leaks?

Its a copy of another companies......

Say bye to low/mid range torque.
Plazmaman plenum and DBW is way to go. Their rail bolts on too with no issues.

I run radium everything, rail, reg, 2 x fuel pulse dampers in the rail... I can confirm the quality is on point!
