Ever wondered why we use ethanol in our gasoline? With ethanol in the mix, the fuel has a higher octane rating, and it also becomes more eco-friendly. But, it also takes a toll on the fuel line of our vehicles. Statistics suggest the number of fuel hose failures is on the rise since the late ‘80s when the use of ethanol in gasoline had started. To make sure your fuel line stands a better chance handling ethanol infused gasoline, you must use the best fuel line material.
This guide will explore the best fuel line material offerings in the market. We will also walk you through the process of identifying and purchasing the best material for fuel line.
Finding the best fuel line material can always be a deal changer! A good one can last you for years without any failure. But finding one is not easy, especially for a beginner. That’s why we’ve picked 10 fuel line materials for you that are currently leading the market in terms of quality and price.

Best Fuel Line Material: Buying Guide
No thanks to the corrosive characteristics of modern fuels, you need to be super cautious while selecting the fuel line tube for your vehicle. The additives found in current-day fuels can degrade the construction of ordinary rubber hoses and also make the fuel contaminated with fuel tube debris.
Therefore, to plumb your fuel lines properly, there are no alternatives to resorting to the best fuel line materials. If your fuel tube gets damaged, it will block the free passage of oil and impose detrimental effects on fuel injectors and the carburetor. Overall, it will compromise your entire engine function.
Here are some factors you need to remain mindful of while selecting fuel line material-
You can fill your fuel tank with many different kinds of fuels. Not engines are created the same, and not all of them have the same source of power. Gasoline has been the most common form of fuel in our world over the past century. But now, there are a lot of alternatives to pick from-compressed natural gas, diesel, biodiesel, ethanol, etc.
These fuel types don’t act the same, and each of these has different effects on the fuel tube material. Therefore, you need to pick a substance that specializes in tackling the fuel you use. What works fine for old fashioned fuels like diesel, might not prove to be as effective on ethanol-based fuels. So, make sure the tube label specifies its ability to convey the type of fuel you want to use.
Flexibility is another important aspect to look at. Even if your tubing does a good job of resisting the decaying effects of the fuel, it will still hold you back if the tube material is too rigid. We can cite PTFE (Poly Tetra Fluoro Ethylene) as a perfect example of this. The plastic variant will have no problem in putting up with all kinds of conventional fuel.
The problem arises when you try to bend a PTFE line. You would find that they are quite stiff and thus not suitable for many applications. You would have a hard time installing the tube if it is not flexible enough. If the tubing bends easily, then you would also find it useful for future maintenance.
Pressure & Temperature Tolerance
Any fuel tube you consider buying must remain functional amid abrupt pressure and temperature fluctuations. The fuel lines come with PSI markings, which symbolize their capacity to combat pressure. The PSI number does vary with the quality of fittings, but you need to see that your fuel tube can deliver a minimum of 3000PSI of working pressure rating regardless of the situation.
Temperature is a key factor to be taken account of before choosing any engine component or accessory. The temperature drives high when the engine operates. In a healthy engine, the temperature could easily cross the 200°F mark. So, the fuel line has to be ready to tackle such high levels of temperature.
However, only high-temperature resistance is not sufficient for the fuel line to fit the bill. In winter, when the temperature plummets to sub zero levels, your fuel line material needs to cope with the chilling atmosphere and keep the fuel transmission active. Otherwise, your fuel line will fail and cut off the fuel supply to the engine.
ID and OD Measurements
The inside diameter (ID) and outside diameter (OD) measurements are pivotal to selecting the right fuel line. The variety of sizes serves a variety of purposes. Wider diameters will accommodate more fuel flow, and narrower ones have lower transmission rates. Now, the question is, are higher ID and OD numbers necessarily better?
No, higher ID and OD numbers do not guarantee a better engine performance for all engines. You should pick the numbers that fit your engine well. An enormous inflow of fuel might turn out to be an overdose for your system. Look up what ID and OD numbers suit your engine perfectly and purchase accordingly.
A shorter tube length would do you no good, so it is a no-brainer that you should buy a tube that gives you ample tube coverage. However, should you buy the exact tube size that fits your engine? Or should you choose to buy a lengthier one? This choice comes down to personal preference, to be honest.
If you ask for our opinion, we would suggest going for a larger tube size. This will give you insurance if you are not sure about the precise tube size you would need. You can cut it in pieces and use them in other projects. But, some people do not want to go through the trouble of cutting and resizing. If you happen to be one of them, then opt for accurate sizes.
You should assess the durability of a fuel tube before you decide on buying it. Fuel lines featuring premium materials will always stand the test of time. Your ideal fuel line should be corrosion-free and able to survive extreme temperature and pressure conditions. It should also bear up against the degenerative effects of modern fuels.
Frequently Asked Questions
Q. What is the most common fuel line material?
Back in the ‘80s, rubber hose fuel lines were predominant. But, rubber is no match for the fuel formulations we use today. Therefore, it has become obsolete as a fuel line material. Nylon tops the list of fuel line materials currently used by manufacturers.
Nylon is affordable, flexible, and puts up with all types of fuel pretty well. So, nylon is the most popular fuel line material right now.
Q. What is the best material for fuel lines?
We would say PTFE, also known as Teflon, is the best fuel line material. It showcases an outrageous level of resistance to fuels, both liquid, and vapor. Teflon tubes can carry fuel with ease and the destructive properties of fuels have minimal impact on the material.
However, Teflon tubes do have a significant drawback. They don’t bend easily, but there are accessories that will help you create bends and curves with Teflon tubes.
Q. Should I submerge my fuel line in fuel?
Not all fuel lines have the ability to function while soaked in the fuel tank. Submersible fuel lines are compliant with the SAE 30R10 standards. If you need to buy a fuel line for immersive use, you must buy one that comes with an SAE 30R10 certification.
Q. Are vinyl tubes good as fuel line tubes?
No, vinyl tubes do not make high-quality fuel line hoses. If you insist on using a vinyl tube fuel line hose, make sure that it has been exclusively designed for that purpose. All the fuels we use are some form of hydrocarbons.
Hydrocarbons accelerate the decaying of vinyl and make it fragile within a short period. Once the vinyl tube turns yellow, you should replace it.
Q. Are copper tubes good as fuel line tubes?
Copper is quite desirable as a fuel tube material. What makes it attractive as a fuel line hose is its malleability. You can form impressive bends and curves using copper tubes.
However, copper tubes do tend to become stiffer when they age, but you can remedy these problems using bending tools. Or, you can simply change the old one for a new tube.
Q. How often do you need to change your fuel lines?
You can expect your fuel line to last between 10,000 miles to 50,000 miles. The durability tends to be better with metal tubes like aluminum and copper. Nylon tubes do not last that long, but they are cheaper and are easier to replace.
Fuel lines play a vital role in the health and performance of your automobile engine. So, you should not rush to pick up a fuel line for your vehicle without doing proper research. Hopefully, following the guidelines in this article will help you find the best fuel line material that fits the needs of your engine.
