Frequently Asked Questions
Is the FPE-34200-15 a direct-fit replacement line for my truck?No. The FLEECE FPE-34200-15 is sold as a universal 15" high-pressure fuel line. It is intended to be bent and routed to match your custom layout using a quality tube bender. For direct-fit 6.7L Cummins injector lines, see the Fleece FPE-FL-CUMM-6.7 series available at CPP Diesel.
What platforms can I use this universal fuel line on?
This line is commonly used on modern diesel common-rail systems, including Ford Powerstroke, Ram Cummins, and GM Duramax applications, as well as custom swaps, industrial engines, and competition builds. Always verify thread size, length, and routing for your specific setup before final installation.
Do I need a special tool to bend this line?
Yes. Fleece and other vendors recommend using a quality hand tube bender designed for 8mm steel tubing to avoid kinking the line and to maintain consistent internal diameter. This gives you clean, professional bends and ensures reliable high-pressure performance.
Can I mix this universal line with OEM and other Fleece components?
Absolutely. Many builders use FPE-34200-series lines alongside Fleece 6.7L Cummins injector lines and high-flow feed line kits to create a complete, serviceable fuel system. Just make sure thread sizes and sealing surfaces are compatible and that all connections are torqued to spec.
Is this line compatible with high horsepower and elevated rail pressures?
The FPE-34200-15 is an OEM-quality high-pressure steel fuel line designed for common-rail diesel use. When installed correctly with proper support and routing, it is suitable for performance builds with elevated rail pressures. Always inspect for chafing, vibration, and adequate clearance in race or high-HP environments.
