Thanks Jerry,

My evaporator cores probably couldn't take a fitting much bigger thant the
AN-16s, but two AN16s in parallel should be as good as 1.4 inch.  The problem
is I run them together into a T with an AN16 out.  The pump is necked down to
an AN16 right at it's entrance, and I'm wondering if the closeness of the
restriction is causing more flow restriction than if it were further away. If I
can find a T or Y block with two AN16's in and an AN20 out, It might help a
lot.  So many questions!

Bob W.
