    The OEM pipe is 12/16mm - 12 mm is Inside diameter of pipe and 16mm is the outside diameter so a 13mm O/D lily pipe is what you want. As for which way to point the spray bar - some poeple find it better to go from the back to the front covering the width of the tank and some people go from the side covering the lenght, I dont there is a right way or a wrong way its just personnel choice.

    Regards

    The lily pipes were designed actually for positioning them on the side, both inlet and autlet. Actually even the distance from the water surface of the inlet is very important to give you a vortex effect which should eliminate the surface scum problem. The bottom of the intake has to be somewhere in the middle of water column. Only this position will give you the best flow...
    Thats would be ideal use of lilies according to amano. Talking about spray bars i dont see a point to put them on the back wall unless it covers all the lenght of your tank.
    I might be wrong ;)
