I just painted mine last week. Removing them is easy, open the hood and stick a 1/4" drive extension or screwdriver in the square hole under the nozzle and pull back on it and they pop right out.
Definitely just take them off. Sniper Focus is right, a flathead screwdriver and some patience and they pop-out. Pop the hoses off first though and put some tape under the holes so you don't spray into your engine bay.
