No. The FPE-34200-16 is a universal high-pressure fuel line. It uses common 8mm x 3.5mm tubing and M14 x 1.5 nuts to fit many CP3, rail, and injector interfaces, but final fitment depends on how you bend and route the line in your build.
Do I need special tools to install it?
A quality hand tubing bender is strongly recommended to get clean, professional bends without kinking the line. Always verify clearance and avoid rubbing on sharp edges or moving components.
Can I use this with other Fleece fuel system parts?
Yes. Builders commonly pair these universal lines with parts like the Fleece high flow feed line kit (FPE-HFFL-1018) and FPE-CUMM-SSFTN stainless tube nuts to complete a high-pressure common-rail system using Fleece hardware.
Is this line rated for common-rail pressures?
The FPE-34200 series is designed for high-pressure diesel fuel applications and built to OEM-style standards. Always follow Fleece’s guidelines and proper torque values to ensure a safe, leak-free install.
Does this product carry a Prop 65 warning?
Yes. Like many metal and automotive components, this fuel line carries a California Proposition 65 warning for cancer and reproductive harm. See the Specifications table for the official notice.
