So...this was a lot more challenging then I was hoping. I started with the drivers side... anyway, the retaining clip came off and fell into the housing and my attempts to retrieve appear to have pushed it further/wedged inside. I guess I'm going to have to resort to removing the head lamps (and bumper). While trying to make room...I removed the secondary air pump. I didn't see any clamp on the hose to the nipple on the bottom of the pump? Is this typical, just pushes on with no clamp? or should I buy/install a clamp?
