Direct replacement for early style Stewart Warner Fuel Quantity Transmitter. Compatible with original fuel quantity gauges and wiring. Viton gaskets and screw/seal assemblies also available. Transmitter, gaskets, and screw/seal assemblies may be purchased separately or in an kit.
These fuel quantity transmitters are direct replacements for the fuel quantity transmitter installed by Cessna when the aircraft was new. This saves hundreds of dollars in labor and kits and eliminates replacement of fuel quantity gauges and wiring when not required. These fuel quantity transmitters are engineered to be compatible with the original fuel quantity gauge and wiring which uses time proven technology for reliability. Each fuel quantity transmitter is manufactured using the new Stewart Warner thick film ceramic resistor technology. The resistor is made by coating a ceramic base with a semi-conductor, and then laser trimming it to a consistent resistance value. The benefits are longer life and increased accuracy. All components are thoroughly tested, ensuring your satisfaction with our product.
Also in these kits are fuel quantity transmitter gaskets are made from Dupont Viton. Viton is the premier elastomer of the aerospace industry, offering flexibility and fuel resistance at all temperature extremes. Viton gaskets will not dry out or shrink like cork gaskets and do not harden with age like gaskets made from other elastomers.
Screw-Seal assemblies have been engineered to eliminate chronic problems associated with fuel quantity transmitter hardware. Hex drive head screws made from stainless steel eliminate the corrosion process. The hex drive promotes ease of installation and eliminates the necessity for destructive down pressure during transmitter screw removal and installation. The stainless steel Viton seal used on the hex drive screw provides a modern solution to leak prevention not available with the originally installed cork or rubber washer.
Do not replace the Rochester fuel quantity transmitter with the Stewart Warner transmitters, as the electrical function is not compatible. Stewart Warner transmitters must be used to replace Stewart Warner transmitters only. Replacing the Rochester transmitter with the Stewart Warner transmitter will result in erroneous fuel quantity indications. Some Cessna aircraft have been modified with a Cessna Service Kit to use the Rochester fuel quantity indicating system. This modification required changing the fuel quantity gauge, transmitter, and other electrical components. Do not use these (Stewart Warner) transmitters as a replacement for these aircraft.
Installed works great
Perfect Fit on my 1973 Cessna 150L
The material was good and the screw holes matched the old seal. The price was the only drawback.

Yes, all the transmitters listed on this page are FAA PMA Approved.
Part # 05-00283 is only the transmitter, but we do have a kit which has the transmitter, gaskets and screws. The kit part number is 05-04110.
Yes, this is the gasket only.
These are wired directly to the gauge so voltage is not a factor.
McFarlane transmitters have an electrical resistance range of about 32 ohms when in the full position and 250 ohms in the empty position.
Yes, that aircraft is on the eligible aircraft list.
This is just the transmitter. We offer kits with all the gaskets and screws, we would just need to know your application. Please contact us directly at 877-477-7823 option 1 for assistance.
The have an ohm range of 35 when full and 250 when empty.
Per Vendor: "The transmitter is the same no matter what side they are replacing. Here is additional info from my tech: To answer the question regarding orientation. Those utilize SAE pattern for mounting. So, the transmitters mount only one way. What it could be they are running into is the tank or wing could be modified or from a different model, that may cause interference with the float. They may have to check with that."
