Pipes/hoses

[northernblue]

Could anyone tell me the correct sizes for

A the hose from the vac pump to the boost solenoid
B the hose from the solenoid to the actuator

I have 26hg at the T piece with my thumb over one hole but when i re attach the pipe from the T to the solenoid i have a fluctuating needle on the gauge.

I'm guessing that 26hg is decent at the T and i have a leak after it.

Can i buy these pipes genuine from volvo and does anyone know the part number ?

Assuming you are claiming 26inch mercury as your pressure. If so this is either too low, as you might be including " 1 atmosphere" in your reading ( depending upon how you achieved your reading in the first place.)
Or
Way to high as I understand the Volvo 2.5T engine is a light pressure turbo and then that figure would be way too high. I can't tell you what your figures are, but my high pressure turbo R would not give those readings. - if I have understood the last couple of days testing and running boost checks.

Can't help on the other stuff, except to say 90% sure Volvo dealers will be able to supply the required pipe work.

Sorry - suffering word blindness - seeing what I thought, not what is actually there. Thought your car was 2.5T PETROL.

Now see its diesel, so sorry can't help.
