Two rads in series with AN -12 is not good. AN -12 flex has a 3/4 ID
or an area of .44 square inches. Way too small. the pump inlet
and out let is 1-1/4 or 1.25 inch ID. The area on that is 1.23 square 
inches so even two 3/4 ID hoses are still too small at only .88 square
inches. 

For a quick temp fix put the rads in parallel like Tracy does. He gets 
away with two 5/8 ID hoses.
