Technical HGT Vacuum pipes

[IanHuntly]

Afternoon all, has anyone got a diagram for the vacuum pipe layout for a Punto HGT, I have a 2004 and am struggling to connect the ones on the off-side (right) side of the cylinder head

What kind of pipes do u mean? I have 3 hgt's maybe i can help u. Do ya have any pics?

There are some vacuum pipes that I think come from under the inlet manifold (notsure) to a unit (variator??) near the brake master on a RHD HGT. This unit has an open vacuum pipe hole 2 - 3 mm diameter and without this the mixture is very lean esp. at low revs.

I should have photos of the intake manifold, I'll check tomorrow. There's blue and black hoses, I think the one you mean is black

That would be great. Perhaps a picture of the engine bay, assuming you have the factory air cleaner setup too would be great.

Can you make any pictures? Its not clear to me, i wanna help.

The unit missing a vacuum pipe is for the variable intake runners inside the Inlet manifold. That pneumatic valve connects to a small pneumatic solenoid under the Inlet manifold (you can just about see it behind the 4 engine mounting nuts, it has two black pipes going to it). The other pipe goes to the Inlet manifold below injector 2, it's really hard to see.
