Started trying to replace my vacuum pipes on my 8v last weekend with some silicone stuff. Got a bit confused as from searches on here was looking for 3 pipes to replace. Got air con on mine so think it differs in set up!
1) Was looking for one that goes to ECU. Took scuttle panel off and could only see a power cable going to ECU. Couldnt see a vacuum pipe going through a grommet into there, although didnt take ECU out. Did find one going to a nipple (no sniggering) on the bulkhead which went to a small 2 - way black box-like valve near the coolant tank, so replaced that.
Borrowing a pic from a post from the other day, the nipple was right by where his two green clips at the back are:

2) replaced one short one from right of throttle body, which is the one near the throttle cable on his pic
Is there another I need to do? And did I replace the right one for the ECU?
On mine, the 2 valves on the hose from throttle body to brake servo have the left one going to the green vacuum pipe (air con???) and the right one is blanked off.
