My distribution header as called out by the manual is leaking. It is round in shape with two cooling hoses and two small plastic tubes connected. It appears that the two small tubes control it in some way. there is also a drain cock along with a orange rubber tube. It appears to me that it is some sort of valve. The two small tubes activate it and allows seawater to flow out the orange tube into the bilge. It is located on the lower right side of the block. Does anyone know what this part is?
