There isn't really any difference between standard Focus Zetec and RS Focus on the impulse (Vacuum & Pressure) lines on the inlet manifold. The large lines to brake servo, PCV, Charcoal Canister have one way valves in them. Small lines to fuel regulator and CC solenoid do not. Only extra line is the MAP upstream (?) of the TB.
