Feed Your Fuel System What It Really Deserves

If you're building power with your Duramax or Cummins and still relying on a stock CP3 fitting, you're bottlenecking your potential.

Whether you're running bigger injectors, pushing more boost, or just want peace of mind that your CP3 is being properly supplied, this fitting delivers. It features a 1/2 inch barbed inlet that significantly increases fuel volume to the pump. Made from high-grade 316 stainless steel, it’s built to handle harsh fuels and resist corrosion long-term. This isn’t just about performance either, it's about reliability. Whether you're towing heavy loads or chasing numbers at the track, this simple upgrade can make a big difference. It’s the kind of part that does its job quietly but backs up every other upgrade you've made under the hood.

Engineered For Higher Flow And Lasting Durability

The Fleece Performance CP3 Feed Fitting is designed to optimize the fuel supply to your CP3 pump by increasing the inlet size to a 1/2 inch barb. This larger diameter allows for improved fuel flow and reduces the restriction that can starve your injection pump during high-demand situations. It is precision machined from 316 stainless steel, a material known for its strength, corrosion resistance, and compatibility with various diesel fuels including biodiesel blends. The fitting comes complete with a sealing washer to ensure a tight, leak-free installation. It is compatible with 2001-2010 GM 2500HD and 3500HD models equipped with the LB7, LLY, LBZ, or LMM 6.6L Duramax, as well as 2003-2007 Dodge RAM 2500 and 3500 trucks running the 5.9L Cummins. This makes it a versatile solution for anyone upgrading or replacing their fuel delivery components. With a design focused on consistent fuel volume and lasting durability, this fitting is a smart investment for performance builds and daily drivers alike.
