Not that I recall Joe, but I remember one time I just started up my car and got out, and saw some white smoke, but since I've had the pump I never seen any smoke. It could have been that I just started the car that cause the smoke at idle who knows. But it wouldn't hurt to replace the old pump for the new one, it's alot easier to use and looks alot better then that yellow pump that would just stick out from everything else.

Also you need to replace it, because if you need to change your fuel filters or you run out of fuel, you won't be able to prime your engine. You probably would be pumping more fuel out of the pump then you would through the engine (that's what my old pump did).
