My Oe DV's diaphram is knackered so im going to buy a forge recirc as a direct replacement. is it a big job to get the old one off and the new one on? also where do all the vacuum hoses go as mines currently dumping through the baileys? ill be looking to chuck the baileys and just run the forge but am unsure how to remove the baileys and rehose it back to normal. anyone done this before and happened to take pics? cheers.
