Hi, I am installing a new genset into a super maramu 2000.
The engine is a kubota with a 50mm hose going to the vetas water lock. On the outlet of the water lock the hose reduces to 40mm. This is how the original is installed. It has a reducer 50 to 40mm glued into the water lock.
Can anyone help with the reasons why the hose is reduced in diameter?
The generator supplier advised to have a 50mm hose going on the water lock outlet.
