Finally a way to increase flow and access fuel pressure on the 2010 thru 2012 6.7L applications!!!

Dodge/Cummins almost got it right this time. The new top loading filter canisters used on the 2010 and 2011 6.7L trucks now have molded in connectors. While they did a good job by stepping up the canister outlet size, that's where the gains stop cold. The filter outlet fitting and line to the CP-3 inlet is only .190" ID. Yes, that's LESS than 1/4" ID. But, we've got the fix in the 2010-2011 GDP Big Line Kit. 

Lose that restrictive line from the fuel filter housing to the injection pump and let your fuel system flow at it's full potential! Gain flow and psi right where you need it, at the injection pump inlet!

The factory fuel line from the fuel filter to the injection pump is pressed on nylon and very restrictive. Our system replaces the tiny factory fittings with our custom adapters and full 3/8" line. Factory fittings are a mere .185" inside diameter as opposed to the GDP stainless fittings with a full .300" diameter. That a 250% increase in flow area thru the fittings!

System includes custom GDP stainless steel adapter, GDP QC Adapter (required for 2010/2011 applications), PushLok fitting, 3/8" hose, clamps and a billet aluminum "T" for adding your fuel pressure sender.
