Frequently Asked Questions

How often should I use a fuel injector cleaner?

For optimal performance, a high-quality fuel system cleaner like Gumout should be used every 3,000 to 5,000 miles, or with every oil change. This helps prevent carbon buildup that degrades efficiency and power.

What is the benefit of an aftermarket performance fuel pump?

Performance fuel pumps (like FASS) deliver a higher volume and more consistent pressure of fuel than stock pumps. This is essential for modified engines that demand more fuel, ensuring the engine doesn't lean out under heavy load, which can cause catastrophic damage.

Do I need a fuel stabilizer if I only store my car for a few months?

Yes. Modern ethanol-blended fuels can separate and degrade in as little as 30-90 days, leading to gumming and corrosion. Using a stabilizer like STA-BIL protects the entire fuel system during any period of non-use longer than a month.

What does 'AN' mean in AN fittings?

AN stands for Army-Navy, a standard originally developed for military aircraft. In automotive performance, it refers to a specific thread and flare standard that ensures a secure, leak-proof connection, typically used with braided stainless steel or PTFE lines.
