All my ventilation hose is deteriorated, and I want to get rid of the dryer hose that was patched in by the previous owner. Measuring across the opening looks like 3.75", but I see various suppliers of replacement hose calling it 4.0". Is there that much difference between outside and inside diameter? Do you fellows recommend one supplier over another? Thanks...Chris
