Welcome to the forums. Yeah, the service manuals don't even have a diagram of how they hook up, but you may be able to look through the pictures in the "fuel" section of the manual and figure out how they go.
If you don't have a service manual, you can go to the manuals/schematics section of the forums and download one.
