2001-2010 GM 6.6L Duramax CP3 Pump Fuel Feed Line Kit 3/8 inch Without Fitting

Any restriction in the fuel flow costs you horsepower. The PPE CP3 High Flow Feed Line Kit eliminates the restriction of the factory fuel test-port/fuel block by re-routing the fuel from the fuel filter housing directly into the CP3 pump. Working in conjunction with the PPE CP3 Pump Inlet Fitting, the large 3/8 inch diameter hose allows for an increased flow to the CP3 injection pump Recommended for Dual Fueler installs and single CP3s where additional flow is needed.
