Yep, it is easy to get the lines mixed up, here are the instructions on where the lines go. Also, you may have a defective fuel switch valve, or you will need to replace the fuel lines to the tank. If there are any holes in the lines, the fuel pump will suck in the air and the engine won't start. Check out the images (below). Please upload pictures or videos of the problem in your response so we can see what's going on.
