Loose Hose

[Elwood]

Doing a bit of work on my R53 today and discovered the unconnected pipe above the supercharger, anyone know where it's supposed to go.

[Dave.]

Is that connected to the fuel pressure regulator, hidden under the fuel rail, underneath the intercooler?

Don't know where it goes without taking intercooler out

[Dave.]

I'd say it does....

Unfortunately unable to help where it goes but the end looks like it has come away from something rather than off a pipe if that helps.
Edit. Looks like the reply above could be your answer

Yup, should be a vacuum hose flopping about somewhere near it....

Just checked, it is the vacuum hose that comes from the fuel regulator but cant work out where the other end goes

See nam link above...

My car does not have that pipe to connect to, maybe not used on my car?

It's definitely used, it adjusts the fuel pressure based on vacuum/boost pressure.

That website suggests its something to do with emissions

Sussed it, found a vacuum take off on the underside of the inlet manifold, could have been like that for some time.

Just took it out for a test drive after fitting a 17% pulley, Airtec intercooler and cooler plugs, awesome

Yup, makes a helluva difference....

Cam, injectors and a tune next....

Assuming you already done coilovers and brakes...

Good stuff.

What you going for?

Not sure yet, any suggestions, the car is only worth 2k so needs to be on a budget.

R56S brakes are a cheap but very worthwhile upgrade.

Coilovers depends on usage, but a lot of people swear by APs for the cost.

I've had ST XTA on mine, can't fault them, had them on for about 4yrs.
