What is a fuel hose?

First things first, what is a fuel hose?

Fortunately, the name makes this piece of equipment pretty self-explanatory: fuel hoses transport fuel from one place to another. However, even though the function is largely set to moving fuel and oil, fuel hoses are used across a variety of applications.

Shanwei Dongze are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Perhaps the most obvious is within the automotive and mechanical industry. Fuel hoses are used to help power machinery by supplying fuel from tanks to engines. They play a vital role in ensuring mechanical equipment is working safely and in a controllable manner. 

Fuel hoses can also be used logistically, like in the transportation of fuels and oils. They’re needed for fuel delivery (from tanker to pump for example), or to suction the material into a container.

Why is fuel hose material important?

Different materials will impact the way your fuel hose performs, so it’s important to understand the qualities you need your fuel hose to have. For example, are you looking for increased chemical resistance? Does your fuel hose need to withstand high pressures? Will your fuel hose be submerged in liquid? These are just some of the considerations that will affect which fuel hose is right for you.

The majority of fuel hoses are plastic or rubber (with other materials like neoprene also useful). However, plastics and rubbers behave better or worse in certain conditions - so it’s worth exploring your options before you choose your next fuel hose.

PVC fuel hose

First, let’s take a look at PVC fuel hoses.

PVC, which stands for polyvinyl chloride, is one of the most-widely produced synthetic polymers (or plastics) in the world. PVC typically comes in rigid or flexible forms as it is mixed with other substances to enhance certain qualities.

PVC fuel hose is made from one of the more flexible forms of this type of plastic, and is used across different machinery and applications. For example, you can use PVC fuel hoses on lawn mowers and other smaller garden machinery.

Top tip – make sure your fuel hoses are properly secured in place with the right hose clips.

Which fuel hose is best for you?

Now that you know the overarching qualities of PVC vs rubber fuel hoses, it’s time to take a deeper dive into which hose is better for certain applications. As we mentioned above, there are several questions you need to ask yourself before choosing your next fuel hose. So, let’s look at some of these answers.

What fuel are you using? 

Diesel, unleaded petrol, oils, and biofuels have different chemical compositions so you need to check which material is better for your needs. 

PVC is very chemically resistant, especially from alcohols. This is ideal for ethanol-infused fuels. On the other hand, ethanol can cause rubber to dry out, so you need to be careful when you choose your fuel hose. Some biofuels can also degrade rubber fuel hoses, so PVC or other polymers may be more suitable.

Note – both materials perform well with regular petrol, diesel, and oil-based liquids.

Is your fuel hose being submerged?

One application where you need to pay particular attention to your fuel hose is when it’s going to be regularly submerged, or likely to get wet.

Boat engines, and other marine applications, need the correct types of fuel hose to ensure the machinery is kept running safely and securely. This is where you should explore specific marine hoses. These are tested and certified to extra standards to ensure they can survive the rigorous conditions.

Do you need a fuel injector hose?

Fuel injector hoses are a vital component in a fuel injection system. These hoses are specifically designed to withstand higher pressures and temperatures, so you need to make sure you have the right one. They’re typically made of strong, synthetic rubber as this material performs well under pressure.

In summary

Overall, the right type of fuel hose will depend on exactly what you need it for. Both PVC and rubber fuel hoses are suitable for petrol, diesel, and oil transmission. However, external factors like pressure and temperature will have an impact on which one is the best fuel hose for your needs.

• PVC fuel hose – these are suitable for low pressure and temperature applications, like in smaller motors and engines. They’re also useful for biofuels and ethanol fuels in particular, or in enclosed spaces.
• Rubber fuel hose – rubber fuel hoses are suitable for high pressure applications, like fuel injection engines. They’re also good for marine applications.
