Wow, you look away for a day and suddenly there are twice as many replies as before...
That's certainly not a factory hose clamp you have there, Replace the fluid, hoses AND the cap as well. Good idea. I've got the hoses on order, what's a couple of bucks for a cap?
Or that the drain hose that begins at the cap and wraps around the bottle before exiting at the hole of the black plastic cover isn’t linked or blocked in any way. I'll check that.
Looking at the first photo again, it also may be that the hose is not correctly seated on the fitting; notice how it's at kind of a sharp angle where it leaves the fitting, which is not normal. I think that's the angle of the photo. Everything looks like the parts schematic and nothing seems pinched or stressed. It's hose #32 coming in from the left, and #29 up from below.
Love the foot powder idea, I'll give that a shot. Maybe I don't need all 5 hoses after all.
Thanks, everyone!
