it should say on the cap but it uses DOT 3 brake fluid. figure out where the leak is coming from. if it's near the firewall then it might be the clutch master cylinder. if it's near the front passengers side of the engine that's the slave cylinder. it could also be a bad spot in the line, there is a piece of flexible line to the slave. if it's coming out that fast then it should be easy to spot. make sure you clean the fluid off paint because it will damage it.
