Hi Ken,

I looked at Behr, Diavia and Waeco catalogues for mechanics: seems
pretty easy to fabricate yourself if the equipment is available. But
probably not worth buying all this for just one hose set.
So I was looking to get the hoses fabricated at some typical hydraulic
shop, re-using the existing fittings.

I appreciate your offer and will come  back to it, if my search here
isn´t successful.
Usually, A/C components are cheap in the US, but shipping and tax
usually ruins the whole deal...

I don´t have the foam around the valve, and the speaker out. I will have
a look.
Just had my hand in there 30min ago to get the stiff drain hose out, but
have no oil or green stuff on my hand...
