Can someone clarify the third fuel tank port (pass side tank) connection? I don't see any reference to it in the update.

The Drivers side instructions are clear.
"On the driver side fuel tank (has only 2 fittings and no internal pump), make a short fuel line that simply loops from one fitting to the other fitting. Using the larger lower crossover tube included with the kit these smaller Corvette crossover lines are not needed."

On the Passenger Side.

-This takes care of the first of three.
"Use the quick connect fuel lines removed from the “Y” fuel line and connect the larger 10mm fitting to the ⅜” rubber line and attach it to the larger port on the passenger side tank."
-This takes care of the second of three.
"Return line
Use 5/16” rubber fuel line along with 8mm connectors on both ends of the line. Install one 8mm fitting into the end of the 5/16” and connect it to the center port on the passenger side tank (the only 8mm port on the passenger side tank)."

After that it goes into connecting the electrical followed by the 2004 tanks.
