Birkin: What is this device?

I need to know what this device is. Is it for controlling the heater?

 

I'm standing on the left side of a 2003(?) Birkin with the Zetec engine, so the left side of the photo is towards the front of the car.

 

On the left of these photos are the spark-plug wires heading forward to the engine.

 

On the right of these photos is the heater core with two heater hoses coming out of it.

 

In the middle of these photos is the gizmo I want to identify. It's in my way. If it is needed only for the heater, I would like to make it go away. I do not need a working heater. I can bag it and tag it.

The other photo method didn't work

Are those fuel lines? Is that an FPR?

@Vovchandr is right.   An adjustable FPR.

FPR?

In case it matters, this Birkin is fuel-injected.

It looks like the same FPR I ran in my fuel injected Birkin. I think mine was an Aeromotive.

It certainly appears to be a regulator, and fuel makes the most sense. But it also appears as though only one of the barbed tubes is connected to a rubber line. That seems odd if fuel is going through it. Is there a third connection, perhaps on the underside?

[Silber]

For what its worth, with my Birkin having a Duratec and my FPR a different unit, the location is the same as yours:

 

 

This is an old picture I pulled from my other thread, with an arrow added to point out the FPR.

Basically the same regulator. Take a better look and you’ll see the second hose outlet at the bottom..

[pethier]

You all are correct.  There is a hose straight down at the bottom of this device. 

 

I did not expect this to be fuel but I see now that it certainly is.

 

From what I learned about connecting the Hayabusa injection on my Caterham, the fuel line comes from the fuel pump at the back of the car to the rear of the fuel rail.  From the front of the fuel rail it goes to the fuel-pressure regulator and from there it goes to a return line back to the fuel tank.

 

I noticed there is a small-diameter hose fitting on the fuel-pressure regulator with nothing attached to it.  Since I see a similar fitting in in the photo from S1Steve, I expect this is nothing to worry about.  Still, I am curious.  What is the purpose of this little fitting?

[11Budlite]

That's to hook up to a manifold vacuum line/fitting to automatically adjust fuel pressure by throttle opening (manifold vacuum). In general terms, high vacuum @ idle = lower FP, low vacuum = higher FP. Not typically used on our setups. I put a cap on mine just to keep any potential debris out.
