Can You Use Air Hose For Fuel Line

Can You Use Air Hose For Fuel Line?

You may listen to replace the fuel hose with an air hose. Perhaps, it is known as the quick and cheap solution for fuel line systems. But can you use air hose for fuel line?

No, air hoses are not good for fuel lines. Their material design and features are not supported for fuel lines. It may damage the carburetor, fuel filter and increase fire risk.

However, you need some more information to decide about replacing the fuel hose line with an air hose.

Why Can You Not Use an Air Hose for Fuel Lines? Top 3 Reasons

Following are the top 3 reasons that make air hoses unfit for fuel lines. Let’s take a look at the facts. 

  1. Material

Air hoses are made of traditional rubber or plastic materials that are not durable as the high-quality Teflon used for fuel lines.

It has low resistance to fuels, and over time the fuel filter and carburetor fill with the rubber material. If it continues for longer, you may experience severe external and internal damage to the line.

  1. Design

Air hoses are designed for pneumatic applications that may not guarantee the best performance in fuel applications. Its durability and pressure resistive ability decrease over time.

  1. Fire resistance

For the fuel lines, it is essential to have fire resistance features. But unfortunately, air hoses do not have this feature. 

So never use air hoses in fuel lines. They are found less effective when used in engines or hot equipment.

Can I Use an Air Hose for the Fuel Return Line?

Somehow you can use an air hose for the fuel return line. There is no need to have high-pressure resistive lines for the fuel return line. 

Where Should I Use the Air Hose in Fuel Lines?

You can temporarily use an air hose in less than 50 Psi fuel lines. But never use above 50 psi.

Final verdict

Air hoses are flexible and suitable for several applications. But never use them for fuel lines, especially when pressure is more than 50 psi, even temporarily.  You will be at risk of leakage, rubber accumulation in the carburetor and filter, and fire.
