I will show how properties such as spin, mass, and couplings of ultra-light (fuzzy) dark matter can be tested with binary pulsars by searching for secular variations in the orbital parameters. In particular, if fuzzy dark matter is a carrier of a vector fifth force, for example B-L, the constraints obtained with this method are the most stringent on the market.
