Everything needed to refresh both driver and passenger side fuel rails. 【Superior Fuel Resistance】 The included Upgraded Red Fuel Hoses are engineered for maximum durability against diesel additives and high temperatures. They provide excellent flexibility for easy routing while maintaining a tight, pressurized seal. The OEM plastic return lines are prone to becoming brittle and cracking over time due to constant heat and engine vibration, leading to fuel seepage. This not only causes waste and unpleasant odors but can also lead to unstable fuel pressure, affecting engine performance and posing potential safety concerns. The core advantage of our kit lies in its all-metal fitting construction. Manufactured from quality materials for excellent corrosion and heat resistance, it eliminates the inherent aging issues of plastic components. Every connection is precisely machined and paired with high-performance seals to ensure a completely leak-tight fuel return circuit. Upgrade Today and Eliminate Fuel Leak Worries!
