New Guy Asks.Water pumping parts?

Hi Guys, I’m pretty new to pumping and started with a Bathmate. While doing my due diligence, I learned that a gauge is a necessary piece of equipment. I just can’t grasp how to convert an LA Pump for use with water. If anyone can steer me in the right direction and identify specifically what parts to order and how they operate together, it would be much appreciated. I’ll first make sure to measure myself before ordering. Thanks.

All you need is a water trap (fluid reservoir) to insert inline between the pump and the cylinder. Its purpose is to catch any fluid before it reaches the pump as fluid in the pump could (will) damage it. LA pump sells one or the basic brake bleeder kit found at automparts stores everywhere, Harbor Freight, even Amazon includes one along with a vac pump.
