Fantastic Bargain
by Bruce from Lexington Park, Maryland on June 23, 2016
With most other companies selling the manifolds and gasket sets separately, this was a nice surprise. All gaskets, hose connectors and pipe plugs included. Was out of the box and installed in minutes. Great product. Highly recommended.
