Just had to do mine and this is what made me start to worry. When I turned the key into run position and the pump did it's preprime cycle it actually sounded like it was dragging compared to the fast high pitched whine it should have. Then I started to have to cycle the key a couple times to get enough prime and pressure for it to fire off right away.
Something else interesting was that my engine was running super lean and I was getting better fuel mileage than these should normally get. I have a feeling my mileage is going to go down now, I can now even hear a better pop from the exhaust each time a cylinder fires.
