How do you top off your hydraulic fluid?
 

I currently use a pump sprayer with push to connect fittings.
It works but leaky and messy.
Looking for a better way…

I have used a levered oil can forever, such as an ARES 55010 – 16oz Red Lever Style Oiler Can. This is just an example of the type of oil can. I only get one use from the cheap plastic hose; the petroleum makes the soft plastic rigid. If there was a leak I would pull a vacuum from the caliper using a snap-on brake vacuum; nothing wrong with the fluid, and it can be reused.

I just topoff periodically until it drools out the overflow below the engine.

Also, with short plastic tube, also great for filling brakes from below.

Put towel over pedals and again, fill until it drools out the top of the brak cylinders.

Drool drool, everywhere...
