I could not bring myself to install a plastic suction manifold that has a critical point of failure like the DD15 has.
I made this Modification, so in the event that it does fail I won't loose ALL my oil pressure. Hopefully it works, what do you think? Maybe later someone more talented than me can make a solid Billet Aluminium version.
Hope this helps.
