Does anyone know what the diameter is of the 2 pieces of hose that connect the pump cartridge to the metal lines inside the tank are? The hoses pretty much disintegrated when I I tugged on them to get the cartridge out. Waiting on my new pump to arrive and figured I'd get this sorted out in the the interim.
Thanks

My best guess would be 8mm ID, as is the rest of the system.

#7 in the attached parts drawing.
