Leaking Hydrotech - HELP!

I have a Hydrotech 4 stage R/O undersink system. It has developed a leak at the Inlet valve cover (PN 20500066). So I replaced the shut off assembly (PN 40600010) and the two Inlet Valve cover O'rings (PN 34201024) but it still leaks. (I also replaced all of the filters at the same time). When you look at the top of the Inlet Valve Cover, there is a small proturbance (possibly a weep port or something) and that is where the water is leaking from. I am not sure if I should replace the actual Inlet Port Cover or if there is something else that I should be looking at. The Inlet Port Cover is hard plastic and I find it hard to believe it could go bad. Any help would be appreciated.

Thanks,
Lee
