    450 fuel line size

    What size fuel line works on the GS450 L. I would check but I am not at home and I went to replace it with the good stuff from gates.

    Automotive fuel line is fat (braided construction to resist high pressure, which is not present on our bikes) so it's harder to route and it also requires a clamp. The stock Suzuki fuel line is thin and stretchy so it holds on the nipples without needing a clamp.

    To measure is to know.

        Thanks! I am going to get some Gates Barricade fuel line. The Gates rep showed us there products and why they are different today at school. http://www.gates.com/downloads/BarricadeBrochure.pdf

          Interesting.
          I am going to see about getting a 25' roll of the F.I. hose due to the higher temperature rating.

          Thanks for the tip!

            I used 8mm inside diameter for the fuel line and used clamps just in case, 6mm for the vacuum line and again with clamps just in case. Also, breather outlet is 12mm from memory.

              Sorry, I still prefer to use the OEM fuel hose in its stock 7mm size.

              It is SO easy to work with, does the job PERFECTLY (without clamps) and has lasted for as long as I have been using it (7 years, so far).

              It only looks expensive when you go to buy it. Depending on your source, it might be $15-20, but you get SIX FEET of hose, and you only need about a foot, so you get plenty for your entire stable.

              All that reinforcement is nice in a car, but our bikes only have a fuel pressure of about 2 or 3 psi, so it's not really necessary.
