DeatschWerks 6-604 X2 Series Pump Module -8AN PTFE Plumbing Kit

The DeatschWerks 6-604 is an X2 Series Pump Module -8AN PTFE Plumbing Kit designed to complete a full return-style fuel system for the 2011–2019 Ford Mustang. Because the X2-Series pump module operates exclusively in return-style fuel systems, this kit provides everything needed to properly plumb the feed line, return line, regulator, and filter connections in a single package.

Constructed with PTFE (polytetrafluoroethylene) hose, this kit offers superior fuel compatibility, high pressure resistance, and long-term durability compared to standard rubber fuel lines. The -8AN feed line sizing supports high-flow applications and is designed to handle the demands of high-horsepower builds.

Key Features:

• -8AN PTFE hose construction rated for up to 1000 PSI maximum pressure
• Precision-engineered AN fittings for secure, leak-free connections
• Compatible with return-style fuel systems only
• Includes all required fittings and hose lengths for a complete installation
• Suitable for a wide range of fuel types including E85
• Constructed to meet or exceed OEM specifications
• Backed by DeatschWerks' 3-year warranty covering defects in materials and workmanship
