Bk sm250 drawing water through the air inlet

[Madreefer]

Well on my skimmer which I beleive is same pump, my skimmer wasnt making any foam. I took it all apart and found that the rubber tubing was full of salt creep. Put it all back together and it was gurgling as well but fixed. So seen there was water in the tube and just blew in the hose while the skimmer was running and it fixed the gurgle sound. I alsotook the muffler off of it. It was kind of damp so might be part of the problem.
