Vacuum from distributor and FSE

Hi guys,
The engine I've built is a 3.5 EFI my distributor (35DM8) has two outlets one in front and one on rear. I've connected the front one to the inlet manifold but where does the second outlet go to?

The second vacuum question is ive also fitted an FSE power boost valve, this also has a vacuum take off, where does this connect to?
Cheers paul

The second connection on the dizzy vacuum unit is not used. Usually has a cover over it.

The fuel pressure regulator vacuum feed is on the back of the plenum.

Hi dave, I've looked on the rear of the plenum but cant see anything to attach the vacuum pipe. I've hopefully attached a photo.

That link seems broken.

You don't say what the injection type is, but on the flapper the vacuum outlet is on the over-run valve housing - the lump on the back of the plenum.
Think that is the idle stepper motor on the hotwire.

Hi Dave,
hopefully I've sorted out the broken link.
I have the flapper type, I cant see any other outlet on the over-run valve except for the inlet?outlet which are 16 mm.
