    dont quote me but,when you move that rod that connects to cam,you should get a suction/ppushing action from the pump.if you need to check for leaks then hook it up to rubber lines and a five gallon bucket and move that rod up and down or in and out(i forget exactly how it goes)and see what it does.
    that s what i would do.

    two things to do. One, put it in a bucket of water with hoses comming out of the water, and pump it by hand under water, this way if its leaking you'll see air bubbles. Two, do the opposite, one line under water and pump and see if it moves water......just my .02
