I have a roller that came with no fuel line and some brake lines missing. At the rear axel there is a block that the rear lines are connected to and off of the block is a rubber line with another block connected to it. This block has a hole through it but has no threads in it. How does the brake line from the front connect to it ? I also need to know where the fuel lines are routed from front to rear? Any help or pictures showing this would be appreciated Thanks...
