Description: This 'high flow' PPE CP3 Pump Inlet Fitting (Part Number: 113060501) is a great upgrade for your 2001 - 2010 GMC/Chevrolet HD with a 6.6L Duramax engine. By using it, you can eliminate possible cavitation damage to the CP3 pump caused by the excessive suction of the high - pressure CP3 fuel injection pump. The larger inner diameter of the PPE fitting allows fuel to flow 70% more efficiently than the restrictive stock 1/4 - inch inlet fitting. With more fuel available, the CP3 injection pump can perform at its best. It's made of stainless steel. Note that the 3/8” version is the maximum fuel pump inlet size, and a 1/2” fitting can connect a 1/2” hose to the 3/8” fuel pump inlet.

Using this CP3 pump inlet fitting is easy. First, make sure your vehicle is turned off and cooled down. Then, carefully remove the old inlet fitting from your CP3 pump. Next, install the new PPE fitting in its place, ensuring it's properly tightened. When it comes to maintenance, regularly check the fitting for any signs of wear or damage. If you notice any leaks or issues with fuel flow, have it inspected right away. It's important to remember that the 3/8” version is the maximum fuel pump inlet size. If you use a 1/2” fitting, it's designed to connect a 1/2” hose to the 3/8” fuel pump inlet.
