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.  |

I have ran a one line system for many years, some guys will utilize a return line, but why?
Also, I run the Webers on several of my cars on 2 - 3 psi. They have never been fuel starved and Webers are sensitive to over pressuring. |
