Installing the Aircraft Specialty hoses RVC102 and FVC103

Where does the RVC102 Return line to Check Valve hose get installed?  Does it replace the existing braided line that is on the engine?

FVC103 Firewall to Check Valve Line won't reach from the check valve as installed by ULPower. 

But it does seem like the combined pair will reach from the engine to the firewall.  That seems to support my hunch that the RVC102 replaces the ULPower braided line.

Should I be asking Zenith for updated assembly instructions? The company website instructions are dated 2012 and there's have been many changes along the way.
