OK, i get carbs only need one fuel line, but hey, there are 2 sticking out of the bottom of the tank.
I Did the Tangerine SS lines to eventually go back to FI, but going with the Webers to get the thing up and running. Out of the tunnel and into engine bay, what's going on with the orphan fuel line? Block it off out of the tank or in the engine bay? Which one gets blocked off? The one with the tank screen filter or the other? And What the Hell is this little white tube? Is it for the FI or does it have some function with the carbs? I don't think so but I keep seeing this tube in my disassembly pics.  |

 Supply on left bottom, return on left top. Top left bolt restricts fuel flow and adds pressure to system at carb take offs at 2 face ports. |

I'm using a Holley fuel pressure regulator and have a gauge on it with no return - works great.
Learned early from Weber experts that they run best with pressure right at 3 psi. Nice pump from NAPA runs about 5 psi max. and the Holley regulator keeps it where it should be. Not expensive either: https://www.holley.com/products/fuel_system...rs/parts/12-803 GN QUOTE(BK911 @ Dec 7 2022, 04:34 PM)  Supply on left bottom, return on left top.
