560 SEL B1 hose replacement
 

My 1991 560 SEL has a leak in the high pressure hose (B1) off the hydraulic suspension pump. Does anyone have any experiance replacing this hose? I'm trying to figure out if the hose can be replaced by snaking the new one I have through the guide supports that mount to the engine or whether lots of stuff (alternator, water pump, etc.) have top come off to provide room to work. Either way it doesn't look easy. Help needed please.

Thanks,
