2006 Seadoo GTX STD Leaking connector

[1963signet]

What system of the jet ski is the yellow connector and hoses for? 2006 SeDoo GTX STD. This is at the back of the hull. The yellow connector has a hole in it. It sprays lake water only under acceleration. Had 5 gallons in the bilge after one hour of riding for the first time this season. It wasn't leaking last season. I can not find this part on any SeaDoo parts diagram or shop Manual. I might just drive a screw in it. Please educate me on what this is and why it is leaking. I am thinking it froze?

That's part of the bildge siphon system.
Look in the OEM parts listing under Hull.
