Fuel/vac lines? By curiousgeorge (Read 1,544 times)

[curiousgeorge]

Hey guys. I have a gy6 50cc 139qmb scooter and wanted some help replacing my fuel and vac lines. I can't figure out what diameter fuel or vac line I need though. I just have a standard carb too if that helps. So does anyone know what are the standard diameters that these carbs and engines use for fuel and vac lines? My fuel lines have some number and letters on them but i have been searching and so far none of that information has helped me find the propper lines. Any help would be much appreciated.

Go to the auto store and get 3/16" fuel line. You can use it for both the fuel and vac lines. The one exception is that the tank nipple is often 1/4". You can work the 3/16" onto it using some WD-40 (no, it doesn't ruin the line), or try to zip tie 1/4" fuel line tight at the other end. Also, Visu-filter sells a 1/4" to 3/16" filter but I'm not sure which way the fuel runs. You can use 3/16" line especially made for the vacuum lines but it's not necessary.

Bashan, should this fuel line be able to also be used as the vacuum lines too ? www.amazon.com/gp/product/B002ZTGLFC/ref=ox_sc_act_title_2?ie=UTF8&smid=ATVPDKIKX0DER

why order stuff when you can buy at a small engine repair shop or an auto parts store? A small engine shop is going to have the best stuff they can buy so that a repair does not come back on them.

Because there aren't any in driving distance from me. I went to five different places today and none of them had the right sizes or any polyurethane hoses either. So does the hoses i posted a link to work as a vac line as well?

Yes it will work well for both fuel and vacuum. It is also long lasting.
