Can I disconnect this hose (see picture) to drain the pa fluid by turning the wheel while keeping the reservoir filled ? (motor off and front end partly jacked to take the weight off front).

Which end will the fluid come from when I disconnect the hose?



I didn't want to crawl under for other hoses. And only sucking out the reservoir may not get all the gunk out?

 

nevermind, I just used my vaccum tool to suck out the reservoir few times between drives. Hoses seems a pain to removec

 

Exactly what I did, made a tremendous difference.
