WTF? It's "boiling" out of the reservoir from under the cap??? Why would this happen? It's not under any heat conditions is it? At least not enough heat to boil the friggin' fluid...

most likely the pump is cavitating heavily and entraining a large amount of air into the pressurized hydraulic system. this gives a perceived boiling effect. many liquids under vacuum on the opposite end for example will also boil. this is closer to a boiling in definition though because heavy vacuum alters the physical properties of most liquids. anyways, replacing the pump is an excellent idea. make sure the lines are all good as well. also make sure to remove the air introduced by new components and disconnections. there is info here somewhere about that. additionally, make sure the vacuum system is not becoming pressurized due to pvc issues or otherwise.
