EFi Vucuum pipe from fuel pressure reg. to ?????

Where does the vacuum pipe from the from the fuel pressure regulator connect to to get its vacuum ? I have the tube at the back of the engine not connected to anything & I cant see anywhere it could connect to ?

it plugs into the inlet manifold, at the back, look hard and you will see it

I had a good look & feel around the back earlier with no luck, hence the question. If its defiantly at the back I'll have to look harder !

I had the same issue just recently.
Unless you happen to be 7' 6" then you have to either sit on the rad and lie over over the lump to find the small stub that the vacuum pipe fits onto. The other alternative is that you propel your 10 year old son up there and get him to do it. Probably best with a cool lump though! Not only is he smaller but his eyes work properly too!!
