Hello All,

I=E2=80=99ve got a Lancair 320 and we=E2=80=99ve just re-installed = the engine and are in=20 the process of the annual inspection.

Both the fuel and the oil pressure readings on the VMS1000 display = are very=20 strange. The fuel pressure gives a reading when there is no pressure and = the oil=20 pressure reads very low. A quick check with some old steam gauges = suggests the=20 actual pressures are about right. The pressure sensors are both in the = engine=20 bay, fed with flexible hoses.

Is this likely to be the pressure sensors? Do they tend to = misbehave? Is=20 there an easy way to check them? Or could it be in the wiring or the = display=20 unit itself. I can=E2=80=99t see anything in the VMS1000 manual about = calibration.

Any help gratefully received.

Thanks,
