Backflow / Delivery
 

The Tank has two pipes (not including the breathers) marked backflow and delivery

I knew one of them peed petrol out but couldn't remember whick one so I guessed delivery (made the most sence)

Low and behold I was wrong :eek:

Can anyone give me a quick 101??

The one on the right side, as sat on the bike is delivery, return is next to it
