10 Best Fuel Line Materials Reviews 2023 | Rx Mechanic (2024)

All was well until gasoline was reformulated to have ethanol. In the past, cars used to have a neoprene runner fuel line which lasted for quite a long. Well, now that most gasoline has about 10% ethanol, the chances of fuel line leaking have increased. You will, therefore, need to buy a fuel line for your vehicle from time to time. Now, what are the best fuel line materials?

A fuel line’s main purpose is the bring fuel from a storage tank to a car or from one point to another in the fuel system. Fuel lines are found in different materials. You can find fuel lines made of metal, reinforced rubber, or stainless steel. The main reason for leaking fuel lines in metal is corrosion, thus needing replacement after a while. This guide will advise on the best fuel line materials with their pros and cons. We shall also inform you on how to ensure you get the best fuel lines.

Best Fuel Material Buying Guide

With several brands of fuel lines in the market, you need to know the things to look at when looking for the best fuel lines. Below is a guide on the major things you should look at to the best fuel line for your needs.

Type of Fuel

The major thing you should consider before purchasing a fuel line is its purpose and where you will be using it. This is what will guide you on the right fuel line to fulfill your need. If you will be using the fuel line to convey diesel, it is then crucial to a line marked ‘Diesel’. If you need tubing to transmit high ethanol fuel, then ensure that the fuel line can withstand alcohol blended fuels.

PSI Rating

One of the things you need to consider when buying a fuel line of its PSI rating. Different fuel lines have different PSI ratings. The rating should depend on where you are installing the fuel line. While looking at the line’s PSI, consider both the working PSI and bursting PSI of the fuel line. Fuel-injected engines have a higher fuel pressure than carburetors.

Flexibility

Some applications need you to have a flexible fuel line while others don’t. The flexibility of a fuel line mainly depends on the materials used to make it. For instance, most fuel lines made of nylons are so flexible that they can even bend by hand. Some people prefer steel fuel lines. For this, you need to have high-quality Flaring tools to help you with the job. Check for the flexibility of the tube first and see if it is what you desire.

Inside and Outside Diameter

The outside and inside diameters are crucial features to check in a fuel line. Needs differ from one application to another, and thus the sizes are distinctive. Most fuel lines indicate their inside and outside diameters. If they fail to state, the diameter given is mainly for the outside. Ensure you check if the diameter will fit where you want to use the line.

Length of the Line

Tubes come in different lengths. You should check where you want to use the tool to know the length you expect of the fuel lines. Some people will prefer exact lengths to avoid cutting. Some will prefer to buy a long fuel line and cut it to their desired fitting.

Durability

We all want to buy high-quality products that will last for a long. The best fuel lines to buy should be made with high-quality materials. The best fuel lime materials should be rust resistance, cold resistance, and ethanol tolerance. You will, therefore, be sure that the fuel line will not contaminate your fuel and they will last for long.

Frequently Asked Questions (FAQs)

Q. What Material Is Used For Fuel Lines?

Fuel lines are made of different materials which have both pros and cons. Most fuel lines are made of reinforced rubber. This material is preferred for fuel lines since they prevent kinking and splitting. Ensure that you buy a fuel line material that can contain both fuel vapor and liquid fuel. Other materials of fuel lines are stainless steel, plastic, steel coated with zinc, and nylon among others. It is important to go through different reviews and learn how a specific fuel line worked for other previous users before the purchase.

Q. What Is The Best Material For Fuel Lines?

The best fuel line material depends on your needs. However, the best material for fuel lines is polytetrafluoroethylene or PTFE. PTFE fuel line is made of plastic material specifically known as Teflon. This fuel line material is impervious is resistant to the degenerative fuel effects which could form vapor barriers. However, just like any other thing, it has its cons. It is inelastic and thus vulnerable to kinking. Thus could, however, be prevented when you use a good bending tool when forming bends and curves.

Q. Can I Replace Metal Fuel Lines With Rubber?

If your metal fuel lines have rusted and started leaking, then you need to replace them to avoid more damage. Yes, it is okay to replace metal fuel lines with rubber made fuel lines. Some people prefer to replace just the rusted part, but it is more advisable to replace the whole fuel line. Fuel line rubber materials are reinforced, and they can take high pressure from modern injection systems. Rubber fuel lines are also quite durable, and they will serve you for a long time.

Q. Can Fuel Line Be Submerged In Fuel?

It will depend on the type of fuel line you want to submerge in fuel. There are submersible and non-submersible fuel lines. Submersible fuel lines can survive even when submerged in fuel. Non-submersible fuel lines, on the other hand, are designed to handle fuel only from the inside. Therefore always check if the fuel line you are buying is submersible on non-submersible depending on how and where you want to use it.

Q. Can Vinyl Tubing Be Used For Fuel Line?

Vinyl Tubing is not the best fuel line material unless it is made for that purpose. Plain vinyl tubing should not be used for conveying gasoline, ethanol, or other hydrocarbons. This tubing turns yellow after some time. Vinyl Tubing gets hard after transmitting fuel, thus brittle quickly. Again only use Vinyl Tubing for fuel lines specifically made for the purpose.

Q. Can Copper Be Used For Fuel Lines?

Copper is another fuel line material you will get in the market. It is actually one of the attractive materials for fuel lines. It forms a permanent fuel or oil line and connection. Therefore, yes, you can use copper fuel lines. It is, however, advisable to use new copper fuel lines rather than old tubing since they are easy to install. If you are using old copper tubing, you can soften it through heating to make it easy for bending. Some copper fuel lines can bend neatly with time and patience, but if not, you need to have the bending tools in your mechanic toolbox.

Q. Can You Replace Steel Fuel Lines With Nylon?

Yes, you can replace the steel fuel line with nylon fuel lines. Nylon fuel lines are preferred by many due to their cost-effectiveness. They are also quite flexible and easy to install. Some nylon fuel line materials form beautiful bends and curves even without bending tools. These fuel lines are available if you just want a specific section or even when you want to replace the entire fuel line.

Final Words

Fuel lines play an important role in automotive, and you should be careful when choosing a tube to replace the original fuel line. The guide above has taken you through the best fuel line materials and the features to consider when buying. Everything you need to know about the fuel line should be stamped on it. It is important to confirm the type of fuel tuning the manufacturer recommends from your car owner’s manual before the purchase. Other things to look at are PSI, ID and OD, flexibility, and length of the hose, among other things. It is important to know exactly how you will use the fuel line since some are not ideal for ethanol.
