Missing pipe or not?

[alinton]

Hi all,

I noticed today there's a diaphragm type thing at the top of the engine on my 4.2, tucked away towards the back, with no pipe coming from it.
Am I missing a pipe? Perhaps someone could look and see what they've got there.
It's one of those approx 3" round chambers with an outlet at the centre that a rubber pipe would notmally push onto.
Thanks!

I've got one too on my 97 4.2, no pipe on mine. I've also got a little pipe that comes from the passenger compartment and sits in the air intake chamber, don't know what that does?

Nothing missing - TVR use an off-the-shelf fuel pressure regulator, which on a 'normal' car would be connected to manifold vacuum to alter the fuel pressure. The ECU takes care of all fuelling on the Cerb, so no need for anything connected to vacuum.
