Cummins utilized an engine block mounted fuel supply pump in the earlier 12 Valve Cummins engine. When replacing or upgrading to an electric fuel pump you are able to remove the block mounted by using this billet aluminum block plate.
Starting in 2006 and when Cummins developed the 6.7 Liter engine, they used this same port as an oil drain for the CCV filter. When you replace the factory valve cover with a billet aluminum valve cover, this block place allows you to eliminate all of the factory plastic drain lines.
Our block plate utilizes an included o-ring seal instead of the factory paper gasket. High quality zinc plated flange head bolts are included as well.
