LACK OF FUEL TO CARB AFTER REPLACING LEAKING FLEX LINE, PUMP RUNS CONTINUALLY PUSHING �IR TO THE IN LINE FILTER NOT fuel pump, DOES NOT SHUT OFF. 1978 MGB, thanks for any help |

Air is being sucked in between pump and tank or pump connections have been reversed, or tank empty or poppet valves in pump are not seating!!!!! |

Which flex? I replaced pump hoses immediately after having the ignition on to move the car. On turning on the ignition I had exactly the same thing ... took me a couple of moments to realise the carbs were still full from before i.e. float valves shut so the pump could not prime itself. Started up and a couple of seconds later the float valves opened, pump primed and refilled, and shut off. |

Nice one Paul, but I bet it wasn't the V8. Fuel evapourates in no time on mine! |

As it happens it was the roadster, but the engine had only been running long enough to position the car, so I suspect the same thing would have happened on the V8. Parked hot I can hear the fuel boiling in the V8 float chambers and see vapour pouring out of the vent pipe. |
