where do you find engine hoses. I have a 50 hp volvo penta diesel model md22f. the hose between the heat exchanger and the water pump (for the internal coolant not the impeller for the raw water) needs to be replaced. it is 1.5 inch on one end 1.25 inch on the other end and forms a very tight U. I have tried a marine volvo penta dealer who couldn't find it and 3 different auto parts stores.
