Fuel Presure on 912 Video

in 912 / 914 Technical Questions 13 years ago
Hello Guys,

How many of you have check your Fuel Presure on your Rotax 912 as per Rotax video?

I have try to check it but I can´t remove the allen screw on the fuel distribution block in order to conect the nipple there. :(

I try very hard with the tool to remove the screw, I was thinking I awas going to brake something but the screw does not move! Its look like this screw have loctite.

How do you remove it?

Can I conect "Permanently" a nipple there and then a hose to a Presure sender that will send the signal to my Grand Rapid EIS were I can check my fuel presure when flying.

THX,

Isaac

    Yes you can, I have and show about 3.5 PSI but varies + or - .5 psi on my dynon d180. Not sure if the variance is normal. Does anybody know if a little variance is normal?

    The answer is yes you can put a nipple in the port on the fuel distribution assembly. Use a heat gun and get it good very warm, then hold the fuel manifold with another wrench and unscrew it. many screws on a Rotax and or aircraft parts can be loosened by using a heat gun to warm the part before trying to remove it.

    Hey Roger, at the beginning, I was thinking to heat that allen screw but since that part carry fuel :ohmy:

    I think I going to close the fuel valve, start the engine and let it die to make sure there is no fuel there and then heat that screw.
