I recently started useing Mogas in my IO-360 and have experienced vapor lock during extended climbs. Turning on the boost pump always eliminates the problem, but I am hoping for a solution that would not require the boost pump. I have run a 1.5 inch blast tube down to the mechanical fuel pump but this has not helped much. It seems to me that the problem is in the lines supplying the mechanical pump. I have them wrapped in fire sleve. I have gone back to runnning 100LL in one tank, but would like to solve the vapor lock problem so I can run Mogas exclusively. Is there something else I can do? Suggestions welcome.
