I have a 2.0 zetec on weber carbs and im gonna run it on the esc setup for now, but i wanna make sure something before i fit it.... where does the vacuum pipe go? to the manifold??? if so im gonna have to drill and tap the manifold. Any help appreciated, Ben

Yes you need to drill and tap or weld a stub on. Dont forget the one way valve or the pipe and esc will fill with fuel.
