The TX fuel sender is a sophisticated component that plays a crucial role in modern truck and bus fuel systems. It provides essential level monitoring capabilities, ensuring accurate fuel measurement. Additionally, it incorporates suction and return ports for both the engine and night heater or auxiliary system, facilitating efficient fuel circulation. The inclusion of an air vent is vital for maintaining proper pressure within the fuel tank, while the optional suction filter helps prevent contaminants from entering the fuel system.

Wema TX senders have gained widespread recognition and adoption among leading truck and bus manufacturers across Europe. Renowned brands such as Volvo, Mercedes Benz, Scania, MAN, Iveco, DAF, and Renault have integrated these fuel senders into their vehicles, attesting to their reliability and performance.

The TX Fuel Sender's design allows for extensive customisation, catering to specific vehicle requirements. Designers can tailor the suction, return, heater, and vent ports to meet precise specifications. The sender can be equipped with various port types, ranging from hose tails to quick-release connectors in different sizes. This flexibility extends to the option of blanking off unused ports, ensuring a clean and efficient installation.

While the TX fuel sender comes standard with a DIN plug electrical connector, it can be further customized to include a flying cable and superseal or other connector types, accommodating diverse electrical system configurations.

The versatility of the TX truck and bus sender is evident in its numerous variables, including length, port size/thread, vent specifications, resistance values, and filtration options. This adaptability results in hundreds of different versions, making it essential to consult with experts to ensure the correct unit is selected for a specific vehicle application.

For replacement senders, it is crucial to provide accurate information about the truck's make and model, as well as the manufacturer or Wema part number. This information is typically stamped on the top of the sender. In cases of uncertainty, customers are encouraged to send a photo for proper identification.

For new applications we need to know:

• Manufacturer (Scania, Volvo, M.A.N. etc)? 
• Application (Diesel/Bio-fuel etc.)? 
• Length of sensor (and/or height of tank minus 10mm)? 
• Resistance value (Empty Ohm (i.e. 10) and Full Ohm (i.e.180) =>10-180 Ω)?
• Fitting for suction – dimension and/or quick fit? 
• Fitting for return – dimension and/or quick fit? 
• Fitting for heater – dimension? 
• Fitting for heater return – dimension? 
• Fitting for air vent – dimension? 
• Electronic connector (i.e. DIN 2-4 pin or other)?
•  

The TX fuel sender's compatibility with diesel fuel makes it suitable for a wide range of commercial vehicles. Its aluminium construction ensures durability and resistance to corrosion, while the IP67 rating provides protection against dust and water ingress. The bayonet fitment allows for easy installation and removal, simplifying maintenance procedures.

One of the key features of the TX fuel sender is its integration with night heater systems. This functionality is particularly valuable for long-haul trucks and buses, where maintaining a comfortable cabin temperature during overnight stops is essential. The night heater suction and return pipes ensure efficient fuel delivery to the heating system, enhancing driver comfort and reducing fuel consumption associated with idling.

The optional high or low level alarm feature adds an extra layer of safety and convenience, alerting drivers to critical fuel levels and helping prevent unexpected fuel depletion during long journeys. This feature can be especially beneficial for fleet managers looking to optimize fuel management and reduce the risk of vehicle downtime due to fuel-related issues.

When selecting a TX fuel sender for a new application, it is important to consider factors such as the specific fuel type (e.g., diesel or bio-fuel), the dimensions of the fuel tank, and the desired resistance values. The choice of fittings for suction, return, heater, and air vent ports should be carefully considered to ensure compatibility with existing fuel system components.

The versatility of the TX fuel sender makes it an ideal choice for a wide range of commercial vehicle applications, from long-haul trucks to city buses. Its customizable features and robust construction contribute to improved fuel system efficiency, reduced maintenance requirements, and enhanced overall vehicle performance.
