any one????????

[Adam]

Which ones do you need?
All the vacuum pipes?

Size as in length or diameter?

[benny f gsi,n it]

yer all the vacum pipes diameter

[Adam]

Epc says "Vacuum connecting pipe on end of the plenum, 5mm OD"
"Vacuum connecting pipe to pressure regulator, 8.5mm ID"

[benny f gsi,n it]

so im after some 8.5 inner diameter for the small vacume pipe to the coasting valve and fuel pressure reg

[Adam]

The fuel press regulator wont be 8.5mm hose im sure.

The coasting valve tho, that sounds about right, 8.5mm hose.

Just measure the pipe connections on the regulator and egr. They must connect to the 5mm OD pipe stub on the plenum.
