Default Finally got the new Aux coolant pump in. I busted two

connections at the rear toward the firewall. I uploaded photos to better illustrate. Does anyone know what these parts are called? I need to visit the stealership tomorrow to get these. I know if I don't have a name for them, I'll get nothing but a blank-minded stare from the parts dude.

As you can see, one of the hoses connects to the intake manifold and branches to several other hoses through a valve. The other broken connection is right next to a valve. It is the section of a "T" connection covered in rope.

Any help is Much appreciated.

The first is the spider hose assembly. Big money for that little guy. Probably best to order it online and pay overnight shipping. The second just replace with some vacuum hose from your local auto parts supply place. You can use standard hose clamps on the replacement. Be careful noto to break the 4way fitting as it will be very fragile.

Make sure you get the right spider hose for your car. Having the connection to the back of your IM means you need the later model, not the one that connects to the F-hose which you don't have. Expect to pay $125+.

I broke the same hose during the build (last pic, the connection from the spider hose to the valve cover) - I used some gasket maker and electrical tape to fix it up and have not had any issues with it. Car was just pressure tested too.

The spider connection has the PCV valve, correct?

Inside that roped line, it looks and feels like a plastic piece is cracked. Is that the four way fitting?

Probably. Those things are absurdly brittle. I ended up replacing several during my turbo swap. You can find hose barbs in the hardware section of places like Lowes and Home Depot.

No. I was saying on the braided line that was torn in the first picture. I was just saying be careful removing the line from the "4 way fitting" which is actually call a vacuum check valve.
