Is this fuel pressure regulator standard?

[OllieR]

Hi guys, trying to work out if this fuel pressure regulator setup is standard or not?!

There is one smaller fuel regulator by the strut and the larger one at the front with the blue vac hose attached.

Car was an auto before being converted.

cheers, O

Well, the reg down between the strut and the manifold is clearly not standard.  As to the other one....seeing as I can barely see anything in your photo because you were standing on the other side of the country from your engine bay when you took it.....it is more than likely the stock pulsation dampener that sits on the rail.

Take a photo of the area in question perhaps?

Maybe stand on the same side of the car as the reg and crop the pic down to the relevant area?

Sorry guys! Took some more photos this morning.

looks like a standard regulator (the small one) then some kind of Webber regulator before lines into the fuel rail (adaptor on the fuel rail?)

anyone seen this before?

thanks! O

You could google the part number on the Weber item and find out if it is a reg or a dampener.

You could follow the fuel lines from the supply (the filter attached to the tower is the supply) and up through the various items, including the fuel rail and map out what devices are where, in what order. and what is supplied with a vacuum line, and work it all out for yourself.

It’s definitely an aftermarket regulator, that thing on the end of the rail is an adapter to that replaced the factory regulator to allow a hose to go to the aftermarket one

[OllieR]

I think is a 2.5 bar regulator, well that what is on it PR / 2.5B I’m guessing that’s pressure regulator 2.5 Bar? 

Isn't the standard FPR 2.5bar or 36psi?

wonder why it’s been changed?

[OllieR]

This is how it hooked up

[GTSBoy]

Standard Nissan FP is ~43 psi.

So, no you know that it is not standard.....what next?

He buys my nismo adjustable FPR...it' a steal ;/

How many pesos? I may be interested.

Dunno mate, prob around the 100? Will be putting it up for sale soon, only selling cos it won't fit on the new soon-to-be-fitted rail.

Sometimes the factory item can have issues. My FPR was causing the fuel pressure on the rail to jump around erratically and was changed out for a Turbosmart FPR. 

To me 36psi sounds like on the low side. Mine runs about 45psi but has been tuned and tuner set it to this pressure. It is good they kept the fuel dampener inline it definitely does help.
