Bolt-In Fuel Sender Replacements for General Aviation.

CiES fuel level senders are a physical bolt-in replacement for many general aviation manufacturers for fuel tank quantity. Here you’ll find the models covered by the current FAA STC.

Please note: CiES fuel senders require a power wire for operation.

The complex sender circuitry in a CiES fuel sensor requires an extra wire to operate. For general installations, you can download installation instructions in pdf format or use our online installation instructions index to go directly to the desired section.

Unless otherwise specified, we support 30+ fuel gauges and instrument panels. These are also covered by the STC. If you require support for an existing gauge (aircraft must have a tank and gauge map), please contact us for details before ordering.

We also engineer custom solutions. Please contact us for more information.

CiES Explains

What is a fuel sender?

Fuel senders are components of your aircraft's fuel system responsible for measuring the level of fuel in the fuel tanks and sending that information to the fuel gauge.

The fuel senders are located inside the aircraft's fuel tanks and consists of a nitrile rubber (NBR) float, a hard-anodized aluminum rotor and housing, nickel-plated Neodymium magnets, complex electronic equipment (outside the fuel tank) and other quality components.

As the level of fuel in the tank changes, the float attached to the fuel sender also changes position. The float arm moves inside the rotor, which is connected electronically to the fuel gauge. When the fuel tank is full, the float will be at the top of the tank, causing the magnetic resonance system to send a signal to the fuel gauge indicating that the tank is full. As the fuel level in the tank drops, the float will move down, causing the system to send a signal to the fuel gauge indicating fuel level has decreased.

With over 100,000 CiES fuel tank level sender units in the field and 900,000+ hours of trouble-free operation, we are a trusted ally of GA owners and quality aircraft manufacturers. In addition, CiES exceeds 90,000 hrs. mean time to failure (MTTF), making our fuel quantity one of the most reliable aviation systems in existence.

Common symptoms and problems with bad fuel senders

A fuel sender is a component of an aircraft fuel system that measures the amount of fuel in the fuel tanks and sends that information back to the fuel gauge. When a fuel sender goes bad or fails, the fuel gauge may not accurately display the fuel level. This can be frustrating and potentially dangerous.

Here are some symptoms of bad fuel sender units:

  1. Inaccurate fuel gauge readings: The most common symptom of a bad fuel sender is an inaccurate fuel gauge reading. The gauge may read full when the tank is actually empty, or vice versa.
  2. Fluctuating fuel gauge readings: Another symptom of a bad fuel sender is a fuel gauge that fluctuates between full and empty, even when the tank is neither full nor empty. It may also behave erratically.
  3. Fuel gauge needle sticking: A fuel gauge needle that sticks in one position or doesn't move at all can also be a sign of a faulty fuel sender.
