The John Deere Z335E is a powerful mower with a 2.1-gallon fuel tank. While the machine does have a low fuel warning light, there have been reports of issues with the fuel indicator. To manually check the fuel level, the under-seat gas tank is semi-transparent, allowing users to gauge the fuel level. Some users have reported issues with the fuel delivery system, which may be due to a dirty or out-of-adjustment carburetor. It is recommended to check the fuel tank for any debris or blockages and ensure that the fuel pick-up tube is intact.

The fuel tank is located under the seat and is somewhat transparent, allowing users to gauge fuel levels
The Z335E ZTrak™ Mower has a fuel tank capacity of 2.1 US gallons or 8 litres. The fuel tank is located under the seat and is somewhat transparent, allowing users to gauge fuel levels. This is a convenient feature that enables users to easily check the fuel level without having to open the tank or use a dipstick.
The fuel tank is strategically positioned low on the left side of the machine, with the fuel-fill opening angled for easy refuelling. This design reduces the chance of spilling fuel when adding more. Additionally, the cap is tethered to the fuel tank, ensuring that it remains securely attached during the refuelling process.
The Z335E also features a low fuel warning light that is clearly visible in daylight. This visual indicator serves as an additional reminder to users when the fuel level is running low, prompting them to refuel promptly.
While the transparent fuel tank provides a general sense of the fuel level, it may not offer precise measurements or exact fuel levels in gallons or litres. For a more accurate assessment of fuel consumption, users can perform a simple test by filling the tank to a known level, operating the mower for a set period, and then refilling to calculate the burn rate per hour.
By combining the visual cues from the transparent fuel tank with the low fuel warning light and periodic fuel consumption tests, operators of the Z335E ZTrak™ Mower can effectively manage their fuel usage and ensure they have sufficient fuel for their mowing tasks.

The thermistor that turns the light on is located approximately 6 inches down from the fuel cap
The Z335E New ZTrak™ Mower is equipped with a low fuel warning light that is clearly visible in daylight. This light is controlled by a thermistor, which is located approximately 6 inches down from the fuel cap. The fuel-fill opening is designed to be low and angled for easy refueling, with a large 2-inch opening to reduce the chance of spills. The cap is tethered to the fuel tank, so you don't have to worry about misplacing it while refueling.
The thermistor is a critical component of the mower's fuel system. It monitors the fuel temperature by changing resistance, and its resistance readings correspond to numerical temperatures. This information is used by the mower's ECU (Engine Control Unit) to control various engine functions. A malfunctioning thermistor can lead to inaccurate temperature readings and inconsistent engine performance.
In this case, the thermistor is located approximately 6 inches down from the fuel cap. This placement ensures that it is close to the fuel tank, allowing it to accurately sense the fuel temperature. By being located a few inches below the fuel cap, it can also be easily accessed for maintenance or replacement if needed.
To access the thermistor, you can follow these general steps:
- Locate the fuel cap on the mower.
- Measure or estimate approximately 6 inches down from the fuel cap.
- Look for the thermistor in this area. It may be attached to the fuel tank or a nearby component.
- Once located, you can inspect, test, or replace the thermistor as needed.
It is important to note that the exact location and accessibility of the thermistor may vary slightly depending on the specific model and design of the Z335E mower. Additionally, it is always recommended to refer to the owner's manual or seek assistance from a qualified technician if you are unsure about any maintenance or repair procedures.

The fuel-fill opening is angled and has a 2-inch opening to reduce spilling
The John Deere Z335E ZTrak™ Mower has been designed with an angled fuel-fill opening, which is located low on the left side of the machine. This strategic positioning makes the refuelling process more convenient and user-friendly. The opening measures 2 inches (5.1 cm) in diameter, which is notably larger than standard fuel-fill openings. This increased size serves a specific purpose: to reduce the chances of fuel spilling during refuelling.
The thoughtful design of the fuel-fill opening demonstrates John Deere's attention to detail and their commitment to enhancing the user experience. By angling the opening and increasing its size, the manufacturer has made it easier for operators to add fuel without worrying about spills or messes. This not only saves time and effort in cleaning up potential spills but also contributes to a safer and more efficient refuelling process.
The large, 2-inch fuel-fill opening is a notable feature of the Z335E model. Its size is a significant factor in preventing spills. With a wider opening, the fuel is less likely to splash or overflow during refuelling. This design choice is especially advantageous for a machine like the Z335E, which has a fuel tank capacity of 2.1 US gallons (8 litres). The larger opening accommodates the volume of fuel required and facilitates a smoother and quicker refuelling process.
Additionally, the cap of the fuel-fill opening is tethered to the fuel tank. This design feature ensures that the cap remains securely attached to the machine, preventing it from being misplaced or lost. The tethered cap also contributes to the overall convenience and ease of use, as operators do not need to worry about misplacing the cap during refuelling.
The angled and 2-inch-wide fuel-fill opening of the John Deere Z335E ZTrak™ Mower is a well-designed feature that significantly reduces the chances of spilling fuel during refuelling. This design showcases the manufacturer's consideration for both functionality and user experience, making the Z335E a more efficient and user-friendly machine.

The fuel tank may be damaged, causing the low fuel indicator to malfunction
If your Z335E's fuel gauge is malfunctioning, it could be due to a damaged fuel tank. The fuel sending unit, located in the fuel tank, is used to measure the amount of fuel in the tank and communicate this information to the fuel gauge on the vehicle dashboard. This ensures that the driver is aware of the fuel level and knows when to refuel. If the fuel sending unit is damaged, the fuel gauge will be the first to show signs of malfunction.
There are a few ways to identify a faulty fuel sending unit. One way is to observe the behaviour of the fuel gauge. If the gauge is acting erratically or giving inaccurate readings, it could indicate a problem with the fuel sending unit. Another way to diagnose a faulty fuel sending unit is to use a specialised diagnostic scan tool, such as the Delphi AutoIQ, which can help identify faults in the current and future generation of fuel systems.
Additionally, physical damage to the fuel tank itself can cause the low fuel indicator to malfunction. For example, if the pick-up tube is split or there is debris blocking the fuel flow, it can affect the accuracy of the fuel gauge. It is also important to check if the tank is venting properly, as a blocked fuel tank vent can trigger the low fuel warning light, indicating an issue with fuel vapour venting rather than the actual fuel level.
If you suspect that your Z335E's low fuel indicator is malfunctioning due to a damaged fuel tank, it is advisable to consult a qualified mechanic. They can help diagnose the issue accurately and suggest appropriate repair options. It is important to address such issues promptly to avoid potential damage to the engine or other expensive automotive parts.
To summarise, a damaged fuel tank can cause the low fuel indicator to malfunction on a Z335E. This could be due to a faulty fuel sending unit, physical damage to the tank, or issues with the fuel venting system. Consulting a qualified mechanic is recommended to accurately diagnose and address the issue, ensuring the safe and efficient operation of your Z335E.
