The little pipe is the return to sump...theres a small bung above the sump line in the engine block below the exhaust manifold side towards the back. The large pipe at the bottom is the vent to atmos..run a large pipe down to ground and cable tie it to your roll bar to secure it. The two on the top...1 goes to a hole you have to drill out in your rocker cover...take off your cover and you will see a round circle cast into it at the back..its even got its on gasket formed ready for you...just drill it out and fit a peice of pipe into the hole for you to attach the breather hose to. The 2nd pipe goes to your firetrap/kidney box....this is a small metal box underneith the inlet manifold, it has the long pipe that would have gone to your air box originaly....remove the pipe, insert a slightly small tube to enable the smaller bore hose to fit, run the hose down from the breather tank thru the inlet manifold and onto the pipe. If your running a standard air box just blank off that connection on the box. Job done.
