    Default C3 Ď08 fuel leak

    After smelling petrol I had to pop open the fuel pump cover to discover that the outflow tube is leaking where it clips into the furl pump.

    I took the photo below before realsimg it, but the clip in question is obscured by the cabling.

    Any thoughts?

    Does the whole tubing require replacement or just the clip end, and could the problem lie somewhere else like in the engine, because it looks as if the pump is pumping a lot of petrol and the engine isnít taking nearly as much.


    Thanks

    If you clean up the plastic elbow in the top of the tank unit, you will most likely find it has a split in the plastic. If so, it requires a new tank unit unless you are willing and able to effect a good repair. From Citroen, it is an expensive item to buy, so you might find the part number for your VIN via service.citroen.com and check eBay and the usual local vendors like Dapco, EAI etc.. You might get lucky and find a good used unit, but the split elbow was a fairly common fault with the original issue part.

    Thanks David, just did check it but couldnt find a split. The leak comes out from within the insert/clip.

    You could buy some fuel injection fuel line and use hose clamps to attach it to the pump end and then cut the other hose running forward and attach it a bit further along. You might find another clip on a wrecked car, cut off the pipe a bit further along and then bring it home and try to refit it to the piping using a hot air gun.

    The reason there is excess fuel is because the fuel pump is designed to pump enough to supply the maximum needs of the car - always on - and the engine side of things deals with this by just returning whatever isn't used by the injectors. This is the common way of doing it.

    Thank you all and you were right!

    So I showed the leak to a Frenchi specialist (am in Lebanon on a long vacation), the moment he saw the video he said itís a crack in the pump. He seemed quite knowledgeable as he pointed out replacing the pump will require that special tool, which he has. He also said Chinese-made pumps (in this market at least) are cheap (65USD) and can be sourced easily but wouldnít recommend them. So a week and many phone calls later I got a new pump by Valeo for about 180USD (PSA wanted 350USD!).

    The mechanic will be changing over it later today. Will report back.

    Got the unit and seal replaced earlier today. Taking out the locking bolt proved so diffficult even with the tool. Had to use a chisel to losen it. Also a lot of petrol was lost because the tank was full.

    As an advice to others I would suggest to leave the fuel cap open, drain the tank below half and place a bunch of rags around the pump opening.

    Well a year on, now back in Australia. I took the 180 for a drive about town and started smelling petrol. I opened the cap under the rear seat, lo and behold the pump is leaking (not nearly as much as the one in the C3).

    As this shall be my runner I will need to replace it pronto. Any advice on where to get quality OEM fuel pump in Sydney?

    And perhaps a recommendation for a mechanic around Redfern?
