Ok - The hoses on Rhapsody are 5/16" ID but, like I said there are other standard sizes I've seen too. I used to have a smaller diameter on the discharge of the Racor spin-on filter to the fuel pump. When I rehosed, I changed the barb fittings so now all the rubber fuel hoses are the same size. Remember you have 3 hoses that should be replaced - Fuel tank outlet to fuel strainer, Injector bypass return to fuel tank, and vent hose the goes to a through hull near top of transom. You also have a small section of hose from the Racor filter to the fuel pump.
