What You'll Learn
The Ryobi 825R is a 4-cycle gas trimmer
The recommended fuel type for the Ryobi 825R is fresh fuel that is less than 60 days old. Alcohol-blended fuel is not recommended as it can absorb water, causing fuel and oil to separate or form acids when stored. To prevent this, it is important to drain the tank and run the engine dry before storing the unit. Additionally, it is important to note that the tank should not be overfilled.
The Ryobi 825R has three fuel lines that need to be routed correctly. The first line, which has a fuel filter at the end, comes out of the fuel tank and goes to the bottom fitting on the carburetor. The second line also comes out of the fuel tank but connects to the bottom fitting on the primer bulb. The third line goes from the top fitting on the primer bulb to the top fitting on the carburetor.
It is important to note that the fuel lines can deteriorate over time and may need to be replaced if they split or crack. The correct routing of the fuel lines is crucial for the proper functioning of the trimmer.
The Ryobi 825R is a powerful and versatile tool for trimming grass and weeds. With proper fuel management and maintenance, it can provide reliable performance for its users.

The fuel line deteriorates over time and can crack
The fuel line on a Ryobi 825R grass line trimmer can deteriorate over time and may eventually crack. This is a common issue with fuel lines, especially those made of rubber. There are several factors that can contribute to this problem. Firstly, fuel can soak into the hose over time, causing it to break down and crack. This is known as permeation and is more common in older hoses. The ethanol in modern fuel can also accelerate the deterioration of rubber hoses.
Another factor is the quality of the hose. Some hoses are made of cheaper materials that are more prone to cracking and splitting. This can be due to overtightening during installation or the use of low-quality rubber that degrades faster. Additionally, the hose clamps used to secure the fuel line may not be as durable as the brass fittings on the fuel pump, leading to leaks and cracks in the rubber lines.
To prevent cracks in your fuel line, it is recommended to use high-quality hoses, such as those made by Gates or NAPA. Stainless steel hard lines are also an option, as they are nonreactive to modern fuel and will last longer. Regular inspection and maintenance of your fuel lines are important to ensure they are in good condition and to prevent leaks.
If you notice any visible cracks or leaks in your fuel line, it is important to replace it as soon as possible. A cracked fuel line can lead to fuel leaks, which can be dangerous and cause engine misfires, stalling, and even vehicle fires. Depending on the section of the fuel line that needs replacing, new parts can range in cost from $10 to $530.

The fuel tank should not be overfilled
The Ryobi 825R is a gas line trimmer. The fuel line diagram for this model is not readily available online. However, the routing of the fuel lines for the Ryobi 725R string trimmer model is available. The 725R model has two lines coming out of the fuel tank. The larger line is the fuel feed and has an in-tank filter. This line goes from the fuel filter to the carburetor. The line closest to the rear of the tank goes through the lower case hole of the air filter housing and attaches to the bottom of the carburetor. The second line, which is smaller, is the return line from the purge bulb to the fuel tank. This line comes out of the front of the tank and attaches to the longer/lower fitting of the primer bulb.
It is important to note that the fuel tank should not be overfilled. Overfilling the fuel tank can lead to fuel leakage from the muffler or exhaust. This is usually a result of a carburetor float problem. The float regulates the amount of fuel in the carburetor float bowl. A needle valve attached to the float shuts off the fuel when the bowl is full. If the needle valve malfunctions, the bowl can become overfilled, causing excess fuel to exit through the exhaust.
To prevent issues with the fuel system, it is recommended to use fresh fuel and to drain the tank and run the engine dry before storing the unit. Additionally, the fuel lines should be regularly inspected for deterioration, as they can crack or split over time.
While the exact fuel line size for the Ryobi 825R is not specified, some sources suggest that a 3/32 x 3/16 inch line may be suitable for similar machines. It is important to ensure that the fuel line size matches the tank opening to prevent leaks.

The fuel line kit includes a primer bulb and installation tool
The Ryobi 825R is a gas line trimmer that uses a 4-stroke motor. The fuel line on this model is prone to deterioration over time and can eventually split or crack.
The installation tool included in the kit will aid in the replacement of the fuel line and primer bulb. This process may involve cutting the fuel line at an angle, pushing it into the tank, and pulling it through the gas cap opening. It is important to ensure that the fuel line is long enough to reach the fuel in the tank and that there are no cracks or holes that could impede fuel flow.
In addition to the primer bulb and installation tool, the fuel line kit may also include a fuel filter, which should be installed on the right side of the carburetor, resting at the bottom of the tank. This fuel filter is an important component of the fuel system, ensuring that dirt and debris do not enter the engine and cause damage.
