Beamie,
To some degree you are right. Right now my fuel hoses are OK and they are the standard heavy black uscg type one fuel hose. A couple of them are still the original vintage (2003) but a couple have been replaced. This past fall I saw a new boat that with a cummins that had these heavy duty blue hoses with the crimped fittings and it looked really robust. While the standard black ones work OK and meet the uscg requirements I never liked the screw clamps they use on fuel lines, looks cheap to me. I really liked the look of the hydraulic style fittings and the blue silicon(?) coated hose in the engine room esp when attaching hoses to the engine.
I agree that what I am looking at is little overkill for my application but I don't need a lot of it. Honestly 40-50' would probably be enough.
I also like the look and idea of user serviceable Aeroquip fittings but are they rated for marine use? I have usually seen them race equipment with the SS braided hoses.
