One of the things I needed to do was add a return line for the Airflow Performance Purge Valve. The AFP system doesn't have a true idle cutoff so instead it uses a purge valve to return fuel back to the tanks. This also allows you to circulate fuel to cool the lines and remove any vaporlock up to the spider. The common way of dealing with this mod is to return the fuel to a point just before the fuel selector. This allows you to select the onetank and fuel will run into the other when the purge valve is used. Much easier than going all the way back to the tank. Today I got the line run in the tunnel. Next I am replacing my flexible lines at the fuel selector valve with hardlines and I'll add the final section of the return at that point.
