Bricki--- probably that fuel line is too small and you might have a lot of bends in it which will either cause restriction or aeration of the fuel---- remember pressure is one thing volume is another---- try to take the pressure closest to the carb---also when setting the pressure with an Aeromotive remember that the engine MUST be running you cannot do it correctly with the engine OFF!!!! I don't think you need a return line with that low of a HP engine either.
