Ryobi 6500 Generator Leaking Gas [How to Fix]

A Ryobi 6500 generator can be the backbone of many households, especially in times of power outages or while on outdoor trips.

But what happens when it starts leaking gas, becoming a potential safety hazard and causing inefficient operation?

In this guide, we’ll explore the causes behind a Ryobi 6500 generator leaking gas, and provide you with practical fixes to get your generator running safely and efficiently again.

Ryobi 6500 Generator Leaking Gas

1 . Faulty Carburetor

A common cause of gas leakage in Ryobi 6500 generators is a faulty carburetor.

This issue mainly arises due to the build-up of debris or due to the drying out of the carburetor’s gasket over time.

The gasket is crucial for creating a seal between the carburetor and the engine. If it’s compromised, it allows fuel to leak out.


The solution to a faulty carburetor is initially cleaning it thoroughly to get rid of any debris. If the problem persists, you may need to replace the gasket or the entire carburetor.

Always ensure to use Ryobi-approved parts for replacements to maintain the efficiency and safety of your generator. Remember, when handling fuel and engine parts, always adhere to safety guidelines to prevent accidents.

2 . Damaged Fuel Lines

Fuel lines play a pivotal role in transporting gas from the tank to the engine. Over time, these lines can suffer wear and tear, become brittle, or even crack, leading to a gas leak.

Exposure to harsh weather conditions or chemicals can expedite this damage, causing the Ryobi 6500 generator to leak gas.


The optimum solution to handle damaged fuel lines is to replace them with new, Ryobi-approved fuel lines.

Begin by inspecting the lines thoroughly for any visible signs of damage.

If you find cracks or brittleness, remove the damaged line, ensuring to drain any excess fuel into a certified container. Next, fit the new fuel line, double-checking the connections for a secure fit.

Always remember to work in a well-ventilated area, away from any source of ignition, when handling fuel and fuel lines.

3 . Worn out Gaskets

Gaskets serve as a seal between the different parts of the generator’s engine, preventing the leakage of gas.

Over time and with regular use, these gaskets can wear out, become hardened or cracked, leading to a gas leak in the Ryobi 6500 generator.

The most common sign of a worn-out gasket is a noticeable gas leak around the carburetor or engine of the generator.


The best solution to address worn-out gaskets is replacement with new, Ryobi-approved gaskets.

Start by identifying the affected gasket, usually visible through signs of gas leakage or the smell of gas. After identifying the worn-out gasket, turn off the generator and allow it to cool.

Carefully remove the old gasket and clean the surface area before installing the new gasket to ensure a tight seal. Always remember to follow safety measures while performing this task and consult a professional if necessary.

4 . Loose connections

Loose connections can be another common cause for a Ryobi 6500 generator leaking gas.

This problem usually arises when there is a lack of regular maintenance or service checks, leading to the loosening of hoses or clamps that connect different parts of the generator engine.

Unchecked, these loose connections can cause gas to leak out, presenting a potential safety hazard.


The solution to loose connections is relatively straightforward: regular inspection and tightening of all connections.

Begin by visually inspecting your Ryobi 6500 generator for any loose hoses or clamps. If you find any, use appropriate tools to tighten them securely.

If the problem persists, you may need to replace the loose part entirely. It’s recommended to use Ryobi-approved parts to maintain the safety and efficiency of your generator.

As always, safety should be your paramount concern, so make sure to work in a well-ventilated area and keep away from any source of ignition when handling fuel and generator parts.

5 . Ruptured Fuel Tank

A ruptured fuel tank is a less common but serious cause of a Ryobi 6500 generator leaking gas. This issue can occur due to extreme weather conditions, accidental impacts, or long-term wear and tear.

The fuel tank, being the primary storage for fuel, when ruptured, can lead to significant fuel leakage, making your generator unsafe for use and less efficient.


If you suspect a ruptured fuel tank, the first step is to shut down the generator immediately.

Then, carefully inspect the fuel tank for any signs of damage or holes. If a rupture is detected, the only safe and effective solution is to replace the fuel tank.

You should purchase a Ryobi-approved fuel tank to maintain the safety and efficiency of your generator. This task can be complex, so it’s recommended to seek professional assistance for the replacement.

Remember, when dealing with a ruptured fuel tank, safety should be your utmost priority. Always perform such tasks in well-ventilated areas, away from ignition sources.

6 . Compromised Fuel Cap Seal

A Compromised Fuel Cap Seal is another reason behind a Ryobi 6500 generator leaking gas.

The fuel cap, equipped with a rubber seal, ensures a tight fit and prevents fuel from spilling or evaporating. However, over time or due to mishandling, this seal can get worn out or cracked, leading to a leak.

It is especially common if the generator is frequently moved or roughly handled. A loose or damaged fuel cap can easily cause a noticeable gas leak.


To rectify a Compromised Fuel Cap Seal, the most suitable solution is to replace the fuel cap with a new one. Initially, inspect the seal on the fuel cap for any signs of damage.

If you discover cracks or wear and tear, replace the fuel cap with a new, Ryobi-approved one.

Ensuring a tight and secure fit of the fuel cap will prevent any fuel leaks and also increase the efficiency of your generator. 

As always, exercise caution when handling fuel and fuel components to prevent accidents. 

If you are unsure about performing this task, it’s best to consult with a professional.


In conclusion, it’s important to regularly maintain your Ryobi 6500 generator to prevent gas leaks.

Whether it’s a faulty carburetor, damaged fuel lines, worn-out gaskets, loose connections, a ruptured fuel tank, or a compromised fuel cap seal, each issue can lead to potentially hazardous and inefficient operations.

Regular inspections and prompt repairs will keep your generator running smoothly and safely.
