After trying several hoses from my friendly NAPA dealer, I've got a couple that will work.
Upper - NAPA 9128. It is 1.5" on both ends
Lower - NAPA 7515. It is 1-9/16" on both ends. The water pump suction line is ~1-5/8" but it fits just fine. The hose hits the front of the timing cover so I'll add a chafing shield or cut that section off.
