I have a Honda 6.5HP trash pump with 1.5" NPT male inlet and outlet. I was given 20ft of hard suction hose that has a 2" NPT female coupling. Would there be a problem using this hose for suction from my pond with a 2" NPT to 1.5" NPT reducer at the pump inlet, or will I have suction or priming issues. The outlet hose is 1.25" ID.
