Hello All,
I am looking at replacing a c70 carburetor on my grandsons MPX70 atv. The carburetor that I am looking at looks like it has 2 fuel lines going into the carburetor shut off valve.
Can someone tell me the purpose of the dual fuel supply lines, if that indeed is what they are and how I actually connect them properly?

thanks is advance

Dual fuel line into carb?

 

The reason for two lines is one is for main and one for reserve pipes from the tank. So if your existing carb doesn't have two lines from the tank, you can't fit that carb. In my opinion, putting the tap on the carb is a stupid idea anyway, as you need to be able to remove a carb without draining the tank, so taps should be on the tank, or in the fuel line.
