I have the V-20 on my Saito 180 mounted on a Ultra Stick 120. Before the pump the engine would stop pulling on a vertical climb after a short distance. With the pump the engine continues to climb until the plane gets higher than I want to fly it. Or in other words it performs the way I hoped it would when I purchased it. Remember the pump has an adjustment on it to control the fuel flow. The engine is installed on a Dubro mount with the rubber cushions.

Happy Flying
