PPE 113060601 CP3 Pump Inlet Fitting (2001-2010 Duramax)

70% more flow over stock Stainless steel Note: 3/8” version is the maximum fuel pump inlet size. 1/2” fitting allows for 1/2” hose reduced to 3/8” fuel pump inlet. 1/2” Get the most fuel flow possible from your stock CP3 pump by eliminating possible cavitation damage to the CP3 pump from excessive suction required by high-pressure CP3’s fuel injection pump with this “high flow” PPE CP3 Pump Inlet Fitting. The key is the larger inner diameter of the PPE fitting, which allows fuel to flow 70% more efficiently than with the restrictive stock 1/4 inch inlet fitting. With a greater volume of fuel available to it, the CP3 injection pump will be able to perform at its optimum capability
