5K Intercooler-Throttle Hose

[Steve Sherman]

On my 87 5KCSTQW I just replaced my second of these hoses in a year.
 This is the "Michelen-man" hose, with the corregations and the metal
reinforcing rings.  Two hoses in one year seems a bit much, and I was
curious if any listers had any ideas of what might be causing this hose
to fail so often on this car?  I was thinking that perhaps an engin
mount was going, causing some extra flexing in the hose.  Any other
ideas of what to look for?

TIA
