Peugeot 205 fuel-overflow problem -- I hope!

Discussion in 'Peugeot 205' started by Harry Sabbers, Oct 8, 2003.

  1. Hello all,

    I'm hoping one of you clued-up car-dudes can help put my mind at rest
    (or not, as the case may be).

    I've recently bought a 1990/G plate Peugeot 205 XS and this morning
    for the first time attempted to fill it with fuel. Midway through this
    process I was alerted to the fact that the fuel was snaking across and
    down the driver's side (rear) wheel arch at pretty much the same rate
    I was pumping it. It's perhaps of note that, because of the car's
    angle against the filling pump, I was holding the nozzle in an unusual
    postion (squeeze handle up; nozzle pointed down).

    I wheeled the car to the filling station's parking lot and had a good
    look under the wheel arch to try and find the cause of the leak. I
    discovered an apparently severed pipe running alongside a much fatter
    pipe (which runs to the underside fuel tank, so I therefore assume
    this fatter pipe is the fuel inlet). I don't know what this severed
    pipe is, or even if it's severed at all (perhaps it's some for of
    overflow pipe/system, and meant to be that way).

    I then bought and filled a plastic petrol can and then tried again to
    fill the car: this time, there was no apparent leak and all the fuel
    made it to the now-half-full fuel tank. I washed down the parts of the
    car that got covered in the leaked petrol and, with trepidation, drove
    the car home.

    I'm now wondering what to do. Neither the car's manual nor the Haynes
    book the previous owner passed onto me mention anything about the
    205's fuel inlet, so I have no idea if there's an overflow system in
    place. I do not know whether the smaller (apparently severed) pipe is
    an overflow pipe, or simply a severed (brake fluid?) pipe that will
    need replacing. Perhaps it was simply my mistake attempting to fill
    the car with the fuel pump nozzle at an odd angle?

    Any hints, tips or advice greatly appreciated.

    The hose is the return feed to the tank. Basically it returns any
    unused fuel from the carburettor to the fuel tank. If this is broken
    then fuel will spill out.

    Repair the pipe and this will solve the problem. (You can possibly do
    it with a plastic 'spigot' if it's a clean break)

  3. The hose is the return feed to the tank. Basically it returns any
    Thanks for that sPoNiX -- but would a problem with the return feed also
    explain the leakage upon filling the tank? The fatter pipe leading from the
    fuel-filler-cap/inlet assembly appears intact/undamaged.

    If the fluidlevel inside the tank rises to above the spot where the leak is
    than I would guess it will come out the leak.

    the smaller pipe that runs adjacent the the larger filler pipe is a breather
    pipe, it is connected tt the neck of the filler and again into the tank is there to allow air in the tank to escape out through the
    filler neck while you are filling up with is possible that as you
    were filling the tank some of the fuel ran down the breather and through the
    split in the pipe instead of into the tank.......a simple repair will do as
    long as it is sealed and done with fuel resistant pipe etc...
