I've got an IACV hose that disintigrated when I removed it from the IACV on the '89 245. It's the one that comes off the bottom of the idle motor and then loops back behind the intake manifold and then connects to it, at the same spot where the small flame trap nipple hose connects (see pic)

I'm not near any Volvo parts shops/dealers and I've already gotten one incorrect hose from FCP. They told me I'd be best off getting the part number.

So, if someone knows the number or has access to an 'exploded view' or what have you, that'd be really helpful!
