I do not think the fuel is bleeding down throught the fuel pump. The fuel is evaporating in the float bowl of the carb. This is due to the high temperature of the exhaust crossover under the carb. The solution is to block the intake manifold exhaust crossover. Kits to block the crossover are available from Dick Paterson at Springfield Ignition or Jim Kanomata at Applied GMC.
