The 944 S2 came with a 3-bar FPR, but it won't fit the 951 because it has a threaded fitting for the inlet instead of the 951's barbed tube & hose-clamp arrangement. You can get a 3-bar FPR that fits a 951 from <a href="http://www.paragon-products.com" target="_blank">Jason @ Paragon</a> for a good price.
