Right i front of the oil reservoir, there's a black cylinder that looks like a car oil filter. In the back of it there's a 4 in hose that goes to what I think is the oil pump. (Metal and about the size of 1/2 bar of soap.) What is the black cylinder? The hose is loose and i need to know what it is so I can replace it. I could just take the hose to the shop, but I still want to know what that part is.
