Quick question, I am doing an OPAS delete, the block off plate style kit. Every video i watch has a hose that come from the plump that has to be plugged. On my ski, a 2004 GTI 718 cc, it appears that my opas is linkage controlled only and there is no water flow from the pump and i dont see any hises or fittings from the pump to the opas like i see on other models in other folk’s installs. An I correct?? Thanks in advance for any help. Not really new to ski’s but this is my first one that has an OPAS and i dont wana risk it sinking while its docked up north.
