      Thanks Ed. Think this winter all the bikes are gonna get new fuel lines. gonna have to hit up Motion Pro for some clear line..unless someone has another source. I know price differs from suppliers.

        Good luck finding clear hose in 7mm. I prefer OEM line, like Ed showed.

        By the way, don't be put off by the price you see for that line. Ed mentioned that the "7" in the part number was the inside diameter. Look at the rest of the part number. The 200 at the end is 2.00 meters. Yes, you get about 6 feet of line.

          I stopped at AutoZone, O'Reilly's or Advanced. Can't remember which. Check in their small engine department. I found clear fuel line there, but not sure of the diameter. However, it worked on my Honda.

            I use Tygon, from Motion Pro. Kinda pricey, but it holds up great! The clear from Motion Pro gets hard after a year or so. Jerry

              8mm works fine with clamps.

                So does 1/4". No clams required. Get the more flexible silicone type. Comes in a variety of colors as well.

                  I prefer 1/4" also. Nice to not worry about clamping. On lines that need clamping, tho, I use only fuel injection hose clamps. They don't tear up the hose at all.

                    All the tygon fuel line I bought turned hard as a brick, bought some green 7mm italian stuff just about the same. Ended up buying oem suzuki line. Until someone finds a better clear line I'll stick with oem.

                      If that's all in mm then it's 200mm which is about 8"

                        It's actually in cm and you do get 6ft of it

                          So two measurements in mm, and one in cm?

                          Odd.

                            I have 6 year old Tygon line on my 85 750 that's still subtle but winters here aren't what they are there.

                              I wonder if I did not buy some bad $hit. I bought the Tygon off Ebay. Did a little google search today and found other people experienced the same thing. If anyone has any good experience with any seller in particular I'd be interested.
