Low fuel pressurel indicator Rotax 914

by Guillermo Stein in 912 / 914 Technical Questions 13 years ago

Flying at 10,500 feet 20 degrees Celsius in a Diamond HK36TT motorglider powered by a Rotax 914 Turbo, my low fuel indicator started blinking with and without auxiliary pump, engine ran smoothly for another flying hour.
I do not think it has to do with the fuel pumps.
Could it be the fuel with heat and altitude? Or maybe just the indicator?
I appreciate any related comments.

Check the fuel pressure sensor on the fuel regulator; I had a broken wire on one a couple of years ago. The wire has several layers of heat shrink on it and it was broken at the sensor side.

:) Problem Solved!! The layers of the wire of the sensor were peeled against the Manifold an with the vibration rthe wire was grounding, it was easily corrected.
