How old is your pump? Mine did the same thing and it turned out the the leak was coming parting line where it comes apart. As JD said it is easy to take apart and clean. I did this 3 times and originally tried to get it to seal by just re torquing the bolts at the parting plane. What I learned is it does not take a big leak to draw air into the pump. I finally ended up putting a silicone adhesive along the parting plane to get it to seal and work again my pump was 18 years old at the time. The only tell tale sign was some corrosion under neath the pump which I could not see until the pump was removed. Check this if the other simple solutions don't fix your problem.
