Hi Folks - I have the entire fuel system out of 9140431482 back to the Webers for update, cleaning, etc. (Webers already reinstalled after thorough cleaning.) The gas tank fuel outlet pipe has no hose bead.
Is this normal? Seems odd there wouldn’t be one. Thanks, Bob |

@brant “Fuel sitting above the motor gets hot”
Just so I’m sure I understand, where’s this fuel that’s getting hot? |

QUOTE(Rufus @ Dec 10 2023, 10:30 AM)  @brant “Fuel sitting above the motor gets hot” Just so I’m sure I understand, where’s this fuel that’s getting hot? In the fuel lines that run over the motor to feed the carbs The floats in the carb restrict how much can enter the bowls (flow rate) A return line allows the excess to return to the tank for cooling and less heat absorption No return line parks this excess fuel to cook The excess waits in the line over the motor I have not measured temps. But I’ve felt the hot fuel. It’s got to be 20 degrees hotter than what’s in the tank Why do you think the factory bothered to plumb a return line into a six? I find it funny that people don’t want to modify a six…. Even pump llocation. But don’t think twice about modifying a return system that actually shows in an engine bay |
