Its the extra fuel pressure, VP44's like volume not pressure. It will crank until the overflow valve relieves some pressure. It won't harm the VP at all, just wear out your starter a little faster.

Mine starts right up when cold, but cranks a little more when warm for some reason. Its kinda scary when your used to it firing right up....but you'll get used to it.
