Can anyone help? I am wondering if having a common vent (fuel and smoke)is a problem... having them join just prior to exiting the bottom of the fuselage. I am thinking of just adding a T right before the exit. just wondering if I could get any serious back-up or fuel-kero, kero-fuel blending that could lead to problems......smoke out the turbine or fire out the nozzles....lol

Thoughts??

Thanks,
dd
