Frequently Asked Questions

How often should I use a fuel system cleaner?

For preventative maintenance, most manufacturers recommend using a concentrated fuel system cleaner every 3,000 to 5,000 miles, or before long periods of storage (if using a stabilizer like STA-BIL).

What is the difference between an AN fitting and a standard fitting?

AN fittings are designed to provide a secure, leak-proof seal under high pressure, commonly using a 37-degree flare. They are crucial for performance and racing applications where standard hose clamps or NPT threads may fail or leak. AN sizing is standardized for easy component matching.

Do I need a hard fuel line or a flexible line for my performance vehicle?

Many builders use a combination. Hard lines (like the aluminum tubing) are excellent for long, straight runs under the chassis due to their durability and cost-effectiveness. Flexible braided lines (requiring AN fittings) are necessary for connections that require movement, such as near the engine, fuel pump, or suspension components.
