hey guys just another problem on the zook, i was wondering why the zook was using so much fuel so i had a look and once again my fuel tank has split this is the second time, to me i think this is a vacume, is this true? and would this be related to my stalling problem? cheers in advance |

Check your fuel tank breather isn't blocked. It runs from the top of the tank through to the charcoal canister in the engine bay. I've had a tank split because of this. The 2 obvious signs were the tank visibly getting sucked in at times after driving, and a rush of vacuum when i'd open the fuel cap at the servo. |

I thought it was normal to suck in air when you take the fuel cap off. Every car that I have owned has. |

a properly designed tank should have 0 to very slight positive pressure. depending on breather type. |

I would be worried if i had any sort of vacum in a fuel tank. The sound you hear when you open the cap is fuel vapor escaping. Thats why there is only so much useable space in a tank, as fuel expands as it heats.. I would be checking breathers and charcoal canister lines if there's a vacum. |

A vacuum will also starve your engine for fuel, it is fairly common problem here. we don;t get many over pressure problems, but to me if the tank splits I would think it would be because of positive pressure, not a vacuum? |

so how you said it starves the engine what will this cause because maybe all this leads back to my stalling and idling problem could this be why? |

might not be why, but it might be making a minor problem worse. |
