High-Quality Fuel Line Kit by BD Diesel

When you're chasing more power from your diesel, one of the most overlooked limitations is the factory fuel line. It might seem like a small detail, but that narrow, restrictive line can choke your CP3 injection pump—especially once you start increasing fuel demand with tuning or upgraded components. The BD Diesel Flow-Max Monster 1/2" Fuel Line Kit is a simple, effective way to unlock that bottleneck and make sure your pump gets the supply it needs. This kit replaces the stock supply line with a high-flow 1/2-inch hose, running directly from your lift pump to the CP3. That extra volume helps maintain consistent fuel pressure under load, which translates to smoother throttle response, better top-end fueling, and more reliable performance—especially if you're running higher horsepower setups. Even if your truck is mostly stock, this upgrade lays the groundwork for future performance mods while improving overall fuel system efficiency right out of the gate.

Hassle-Free Install

Installation is quick and painless, usually wrapped up in about an hour with basic tools, and the kit includes everything you need to get it done right the first time. Whether you're building a street-driven tow rig or prepping for competition, this is one of those small upgrades that makes a noticeable difference.
