Help with some part numbers please

[Grant V]

I can't find these parts on any parts diagrams I use - please can someone help with a part number, or confirm the ones that I have:

Hose from the vacuum/ coolant metal pipe to the inlet manifold, as below. Part number?


Pressure hose attached to the union and then onto the silicon hose. Is it 034145746BE?

Vacuum line from the intake manifold to the top of the bypass valve is item 21 in the diagram (that I annotated) below, PN N 10196502 (that is N<sp><sp>101...)

The ABY factory version of that hose is one piece. 034145746AT. The makers of the silicon replacement hoses for some reason did them as two pieces. That said the OE RS2 might be two pieces: 034145746BC and 034145746BE. But check those numbers out yourself.

For the small vacuum hose, I see on the parts diagram that you've referred me to it's described as a hose 4x3 - would this mean 4mm outside diameter with 3mm inside diameter?

That is my interpretation of 4 x 3. Seems thin walled though.
