You say the black pipes have " fuel on them "....that is irrelevant , its what the pipes do which is important , every one has a different attitude to what they fit to engines, fuel line ,air line etc As Rob says....those black pipes are the breathers that go to emission controls and the 1/4" inch tubes at the carb floats are inlet pipes that go to the pump. So, you should have a 1/4 fuel tubing from pump, to the first carb float , a rubber or copper tube from the first carb float leading to the second float . I can now see that the accelerator linkage is blocking view....the two black emission tubes should attach to the rocker cover outlet pipe
