(un)Necessary gauges

[jrthomas]

There's alot of knowledge and experience here-What's your opinion of fuel pressure gauges? Useful or not? What about manifold pressure gauges? My kit came with one.

[SkyPirate]

which motor is on your kit jr?

[jrthomas]

I should have said-It's a 912ul.It came with a manifold pressure gauge so I used it.I'm just not sure why except the hole was there in the panel for it.I don't think I'll have much control over manifold pressure.I have a fuel pressure gauge not installed yet but my Rotax service tech says it's unnecessary.What's your opinion?

[SkyPirate]

hmmm where is the sensor located for the pressure,. the reason why I ask,..I'm wondering if the location was intended for an EGT,..Exhaust Gas Temp in the panel


to be completely honest I have not messed with the 912's much yet,.I believe that ussually manifold pressure instrumentation is installed when a constant speed prop is going to be used,.correct me if I'm wrong

Thanks SkyPirate, The gauge I have is mechanical-Does not use a sender. I haven't installed anything yet but a "T" is to be placed in the fuel line after the engine fuel pump and a wet line to gauge. It's a higher quality (higher priced) gauge than the electronic gauge but I don't feel too comfortable with another fuel line pumping gas toward me. I wondered what others are doing. As for as the manifold pressure gauge goes, it's instaled and working so I'll probably leave it. You're probably right about its purpose.

don't need either.
