Waveline DC 6000 replacement fittings

Hi All,

I am in desperate need of a couple of new fitting for my waveline DC 6000 pump. I have searched the internet up and down and cannot find them let alone a number for the manufacturer. Specifically the suction side. The pump is about a year old and a month ago it started sucking air at the suction fitting. Turn the pump off and it leaks water. I put some silicone on it which slowed it down almost to nothing but it has started leaking again. Any ideas?

Thanks Jason
