    Is it a good idea to put a hydraulic filter (spin on like a truck oil filter) on a conventional Speedcast system? I am piecing an old one together and it would only be another $20 for a spin on filter setup. If so, should it go before belt driven pump or after? I am mostly worried about any old crud being in my system when I first use it since it hasn't been used in years.

    It can't hurt. I have an inline Fisher filter (like an inline fuel filter, only bigger.) It goes on the return line. You have one high-pressure line coming from the pump to the valves. Then high-pressure lines going from the valves to the rams out front. The other line going from the valves to pump is a low-pressure return. That's where you want you're filter.
