In around 2007 the design of the valve block changed, our repair kit fits the design previous to the change in 2007. The later valves don’t tend to fail in the same way. If your valve block has been changed in its life it is possible it was changed to the newer version. To determine if you have the newer model the ABC pump can be inspected on the upper right side of the engine; If a black sphere is attached to the pump it is the 2007+ model.
