Yep, it is sat in the V by the windscreen and dipstick.
The reason I ask is that I was at a BBQ at the weekend and there were a few (5) chaps who are fuel injection lecturers for Land Rover / jaguar. They picked up on the missing pipe and concluded that it would be running too rich and would idle really badly without it.
Hopefully someone with distinct Cerb knowledge will be able to clear this up. A son of one of these chaps later said to me that it wouldn't require a pipe if it were set up to run 'balls out' so to speak. Perhaps this is so.
As you can tell my mechanical knowledge is poor.

Nope, and no problems either. Pipe would normally connect to inlet manifold on 'typical' car, and means that pressure in the fuel rail would be different depending on vacuum in inlet i.e.more pressure for bigger injector squirts when you snap the throttle open. This would be required for simple fuel injection maps where they only map fuel against throttle opening, thus the link to the vacuum effectively richens the mixture over what the map says when you open the throttle.
The ECU on the Cerbera is a lot smarter and takes all this into account when fuelling (I recall it includes a measure of how fast you open the throttle, but I could be wrong). Bottom line is the Cerbera ECU is mapped to expect fuel in the rail/injectors at a constant pressure, so no you don't need a tube, and no it isn't going to mess up the mixture.
