Unloader recommendations

I am looking into replacing my current unloader due to it not having a bypass port I can run to my buffer tank. It appears that it has a short metal line that runs straight from the pressure side to the inlet side for the bypass. I wasn’t completely sure if any unloader with bypass ports would work. Any recommendations on what type of unloader. The machine is a Honda GX390 with a GP 4gpm @ 3500 psi.
