AN Fuel Line Fitting 6AN 3/8 Inch Straight Aluminum EVIL ENERGY

Description

Product Overview

The EVIL ENERGY AN fuel line fitting is engineered for demanding fuel delivery applications where strength, precision, and reliability are non‑negotiable. Crafted from aerospace‑grade 6061‑T6 aluminum alloy, the fitting offers an excellent balance of lightweight construction and exceptional corrosion resistance. The 6AN thread size corresponds to a 9/16‑18UNF specification, while the barb end measures a precise 3/8‑inch outer diameter, ensuring a secure mechanical grip on compatible hoses.

Each fitting incorporates a 37‑degree flare on the AN side, creating a sealed mating surface that can withstand pressures up to 1500 PSI. The straight style provides a direct flow path, minimizing turbulence and pressure drop, which is critical for high‑performance engines and fuel‑injection systems. The exterior finish retains the natural aluminum sheen, offering both aesthetic appeal and additional protection against environmental factors.

Designed for ease of installation, the fitting features a barb that can be pushed directly into the hose without the need for specialized tools. For added security, the manufacturer recommends the use of hose clamps to guarantee a tight, leak‑free seal. The part number EV01757S1BK is recognized across the industry, making it simple to source replacements or upgrades.

With a weight of just 0.634 ounces and compact dimensions of 4.88 x 4.21 x 0.75 inches, the fitting is easy to handle during assembly and fits comfortably within tight engine bays or fuel system enclosures. Its compatibility with a wide range of hose sizes—from 4AN to 10AN—means it can serve as a versatile component in both stock and custom fuel system builds.

Customer feedback highlights a 4.8‑star rating from over 500 reviews, underscoring the product’s reliability and the manufacturer’s commitment to quality. Ranked #13 in the Automotive Replacement Fuel System Fittings category, this fitting has earned a reputation as a trusted solution for both professional mechanics and hobbyist racers.

Usage

The AN fuel line fitting excels in a variety of high‑performance environments. In motorsports, it is commonly employed in race car fuel delivery systems where rapid fuel flow and pressure stability are essential. Its straight design reduces flow restriction, allowing the engine to receive fuel at the rate demanded by aggressive tuning.

For off‑road and adventure vehicles, the aluminum construction resists the harsh conditions of dust, mud, and temperature extremes. The fitting’s operating temperature range of –65 °F to 252 °F ensures consistent performance whether the vehicle is climbing a mountain pass or cruising through a desert heat wave.

In everyday automotive applications, the fitting serves as a reliable replacement for OEM fuel line components. It is suitable for gasoline, diesel, and ethanol blends, making it a flexible choice for a wide array of fuel types. Installation typically involves cutting the hose to length, inserting the barb, and securing it with a clamp—an operation that can be completed in minutes by a qualified technician.

Because the fitting adheres to UNF thread standards, it can be paired with a broad selection of adapters, elbows, and other fuel system accessories. This modularity enables custom fuel system designs that meet specific performance goals without sacrificing compatibility.

Whether you are building a high‑output race engine, upgrading a street car for better fuel efficiency, or maintaining a fleet of work trucks, the AN fuel line fitting provides a dependable connection point that supports the entire fuel delivery chain.
