Hello,

I am a happy owner of a pioneer 300 model aircraft that mounts a jabiru 3300, in this period I completely rebuilt my plane's petrol system, and doing some checks and always using the same electric fuel pump and the same mechanical fuel pump. realizing that the petrol that comes back from the petrol return in the tanks the petrol has a brown color that increases in intensity as it passes through the power supply circuit, I wonder is it possible that there are errors in the materials used for the restoration of the petrol system? I kindly ask you to examine my request for information because it is clear that there is a safety problem due to the possible eventuality of the engine being stopped in flight, have a good day,

thank you

Hello Cicrosso,

It definitely sounds like something isn't right there!  At Jabiru we use black rubber fuel line (specifically made for fuel) forward of the firewall.  Aft of the firewall we use a polyurethane fuel line that is made for Jabiru.  

As you have a Pioneer aircraft you should also contact them as we weren't involved in the fuel system design for that aircraft.  Normally a jabiru engine doesn't have a fuel return line.

Hello,

I used both before firewall and after Akron fuel wp pipe, 10bar, NBR / CR, Din 73379-2A, the same fuel pipe that was installed before my restoration, I don't understand why this new brown petrol color pipe,

thanks for the answer
