DeatschWerks 6-03-4150-6-G 6AN PTFE Fuel Line Kit for 4150 Style Carburetor with Gauge

The DeatschWerks 6-03-4150-6-G is a complete 6AN PTFE dual-inlet fuel line kit engineered for 4150-style carburetors. Designed to deliver reliable, leak-free fuel flow in high-performance carbureted applications, this fully assembled kit eliminates the guesswork of sourcing individual fittings and hose segments. The included fuel pressure gauge port allows real-time monitoring of fuel delivery, making it an ideal choice for performance street and track builds.

DeatschWerks builds this kit around PTFE-lined hose, which offers superior resistance to fuel degradation, ethanol blends, and heat compared to standard rubber hose. The smooth inner bore of PTFE hose also minimizes flow restriction, helping to maintain consistent fuel pressure at the carburetor's dual inlets.

• 6AN PTFE-lined hose for exceptional fuel compatibility and flow efficiency
• Dual-inlet design engineered for 4150-style carburetors
• Integrated fuel pressure gauge port for easy pressure monitoring

• High-quality anodized AN fittings for corrosion resistance
• Designed and engineered by DeatschWerks, a trusted name in performance fuel systems

This kit is a straightforward upgrade for any 4150-style carburetor installation where a clean, reliable, and performance-ready fuel plumbing solution is required.
