Can I use only one filter on the suction?

You can run filters in parallel but they usually on higher flow systems NOTE: Their are specific filters designed for suction use and not all filters will work in suction application.

For a simple gear pump you can use a suction strainer that is made from wire mesh.

On my homemade backhoe, I only run a suction strainer for the pumps and a filter on the return of both pumps.

Whatever dirt or trash that may enter the system during connecting/disconnects quick connects, stay trapped in the filter and doesn't even reach the tank.

The tank has very little risk of contamination in my opinion, as long as precautions have been taken when filling said tank.
