Free Up Fuel Flow and Unlock Performance

If you're running a 2001 to 2010 Duramax, there's a good chance the factory fuel routing is holding your truck back more than you realize. The PPE CP3 Pump Fuel Feed Line Kit with 3/8-inch hose is designed to solve that problem by replacing the restrictive stock test port and fuel block with a more direct, high-flow setup. By rerouting fuel straight from the filter housing into the CP3 injection pump, this kit helps ensure your engine is getting the volume it needs without struggling against unnecessary bottlenecks. For guys chasing better throttle response, smoother power delivery, or just more consistency under load, this is a simple but meaningful upgrade.

Made for Trucks That Work and Play Hard

Whether you're daily driving, towing heavy loads, or building a performance setup with a single or dual CP3 system, this kit is ready to keep up. The 3/8-inch diameter hose allows more diesel to reach the pump with less restriction, helping your fuel system stay efficient even when demands go up. It’s built to work hand-in-hand with PPE’s CP3 Pump Inlet Fitting for a smooth install and maximum benefit. From weekend warriors to serious workhorses, any Duramax can benefit from the improved fuel delivery and reliability this kit brings to the table. It's a smart way to support horsepower gains and protect your investment at the same time.
