Any restriction in your fuel flow costs your truck horsepower, plain and simple. PPE's CP3 High Flow Feed Line Kit works to eliminate restriction from the factory fuel test-port/fuel block by rerouting the fuel from the fuel filter housing directly into the CP3 pump.
Large 3/8inch Hose
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. Fits: 2001-2010 GM 6.6L Duramax Application Notes:
Recommended for Dual Fueler installs and single CP3s where additional flow is needed.
