1. Úvod
The VDO ALAS Adjustable Fuel Sender is a precision instrument designed for accurate measurement of fuel levels in various tank configurations. This sender is adjustable to accommodate tank depths ranging from 6-3/4 inches to 23 inches and provides a resistance output of 10-184 Ohms, making it compatible with a wide range of fuel gauges. This manual provides comprehensive instructions for the safe installation, proper operation, and routine maintenance of your VDO fuel sender to ensure reliable performance.
2. Bezpečnostní informace
Always adhere to the following safety precautions when installing or servicing the fuel sender:
- Odpojit napájení: Before beginning any work on the fuel system, always disconnect the vehicle's or vessel's battery to prevent electrical shorts and accidental activation.
- Větrání: Ensure adequate ventilation in the work area to disperse fuel vapors, which are highly flammable.
- Žádné otevřené plameny: Never work near open flames, sparks, or other ignition sources when handling fuel or working on fuel system components.
- Osobní ochranné prostředky: Wear appropriate personal protective equipment, including safety glasses and gloves, to protect against fuel exposure and potential injuries.
- Fuel Spills: Have absorbent materials readily available to clean up any fuel spills immediately. Dispose of contaminated materials properly.
- Profesionální instalace: Pokud si nejste jisti některou částí instalačního procesu, vyhledejte pomoc kvalifikovaného odborníka.

4. Nastavení a instalace
Proper installation and adjustment are crucial for accurate fuel level readings. Follow these steps carefully:
4.1. Kroky před instalací
- Measure Tank Depth: Accurately measure the depth of your fuel tank from the mounting surface to the bottom. The sender is adjustable for tanks between 6-3/4 inches (17.1 cm) and 23 inches (58.4 cm).
- Adjust Float Arm: The float arm must be adjusted to match your tank's depth. The arm can be carefully bent to ensure the float reaches the bottom of the tank when empty and the top when full, without hitting the tank walls or bottom. Ensure the float has full range of motion.
- Připravte montážní povrch: Clean the fuel tank's mounting surface thoroughly, removing any debris, old gasket material, or corrosion.
4.2. Postup instalace
- Aplikace těsnění: Place the new mounting gasket onto the fuel tank's mounting flange.
- Insert Sender: Carefully insert the VDO ALAS fuel sender into the tank opening, ensuring the float arm and float are positioned correctly and can move freely.
- Bezpečná montážní deska: Align the sender's mounting plate with the bolt holes on the tank flange. Secure the sender using appropriate fasteners (not included) and tighten them evenly to create a leak-proof seal. Do not overtighten.
- Elektrické připojení:
- Connect the sender's signal wire to the fuel gauge's input terminal.
- Connect the sender's ground wire to a reliable chassis or battery ground point. Ensure a clean, secure connection for accurate readings.
- Znovu připojte baterii: Once all connections are secure and verified, reconnect the vehicle's or vessel's battery.
5. Návod k obsluze
The VDO ALAS Adjustable Fuel Sender operates by varying its electrical resistance based on the fuel level. As the fuel level changes, the float moves the arm, which in turn changes the resistance of the sender unit. This resistance change is then interpreted by a compatible fuel gauge, which displays the current fuel level.
- Kompatibilita: Ensure your fuel gauge is designed to work with a 10-184 Ohm input sender for accurate readings.
- Počáteční kontrola: After installation, fill the fuel tank and observe the gauge reading. Then, if possible, drain the tank to verify the empty reading. This helps confirm proper installation and adjustment.
- Normální provoz: The sender will continuously provide fuel level data to the gauge as long as the system is powered.
6. Údržba
The VDO ALAS Adjustable Fuel Sender is designed for long-term reliability with minimal maintenance. However, periodic inspection can help ensure continued accurate performance:
- Vizuální kontrola: Annually inspect the sender unit, float arm, and electrical connections for signs of corrosion, damage, or wear.
- Float Arm Movement: Ensure the float arm moves freely without any obstruction or binding.
- Elektrické připojení: Check that all electrical connections are clean, tight, and free from corrosion. Loose or corroded connections can lead to inaccurate readings.
- Integrita těsnění: Inspect the mounting gasket for any signs of cracking, drying, or leaks. Replace if necessary.
