Westach Instruments has FAA approval on all the instruments listed below. These gauges are fully approved for installation in factory aircraft, so the weight and cost savings of Westach gauges can now be enjoyed by owners of production aircraft as well as home builders. All systems are complete with instrument (internally lighted), senders and leads. All of these gauges fit 2-1/4" panel hole.
Do you carry the sender 378-15 for K38X and sender 378-14 for K37X?
You can call us to special order the probes as when you order the Westach TSO'd kit (like K38X and K37X) the probe comes in the box. We do not get much demand for just the senders but can order.
