The real problem is fuel vaporizing from the heat of the engine mounted fuel pump being heat soaked. Solving this problem EVERY TIME results in the necessity of cooling off the engine driven fuel pump. In the TCM engines and many of the Lycomings which have fuel return lines to the tank do this by running the boost pump for 60-90 seconds with the mixture in IDLE CUTOFF. This circulates cool fuel through the hot pump, cooling it off. Then smply do a normal start procedure. If the fuel pump is cool, there is NO hot start issue. PERIOD. I have yet to have this method fail.
