not questioning you just wondered
 
Thing is though, you don't touch the valve ;)

Step one: remove hose from top of DV
Step two: remove hose from top of FPR and from bottom of inlet manifold that the same hose runs too...
Step three: connect new 4mm hose from DV to inlet manifold
Step four: t piece into same hose to connect FPR
Step five: block off any hoses remaining that not connected
Step six: remove vac res. from coil pack four
