[dieseltdi at verizon.net]

Before I climb under and disconnect all the hoses, does anyone know  
the diameter of the heater hoses that run from the back of the van to  
the front on the diesel vanagon?  TIA  Hayden

one party, a leader who claims to have special powers outside the law  
to keep the country "safe", secret prisons where people are locked up  
without charges or trial and government opponents are branded as  
unpatriotic and charged with aiding the enemy."
