    Wink Fuel pump's lifespan

    Defender 110 - 2005

    Hi everyone, I'm new to this forum and I wonder if I could squeeze some knowledge out of you guys.

    I read that the fuel pumps of the defenders tend to die when the vehicle reaches about 150.000 km or so.

    - Is this a specific issue to some defenders up to certain year or is it all of them ?

    - Mine has no problems as yet, this vehicle only has 70.000 km on the clock, but i wonder if i'll be likely to be facing this problem in the future, and if there is anything I can do to prevent it ?

    - Also, is there a better aftermarket pump out there ?

    its a hitnmiss thing. mine went to 175K Km with no dramas when I sold the vehicle

    some let go before 50K km.

    there's no drop in item as far as I'm aware and IVe done some playing around to work out how to use aftermarket parts inside them with no cost effective easy success.

    I had a genuine Rover pump fail within 27,000km. For this reason I always carry a complete spare in the wolf box now.

    Mine screamed like a banshee for over a year. Decided not to replace due to everyone saying that it was on it's way out. Since then I have remoced and cleaned it and it's still going strong with over 200,000km. I have the replacement ready to go.

    I guess the way to go is to fit an access door to the pump on the cargo area, and keep a new one on board when I go bush bashing.

    I imagine it to be a simple job, to replace the pump once you have easy access to it.
    Are there any tricks of the trade I should know in case I have to do it in the back of beyond ? The more I know about it, the safer I travel with a child on-board.

    I haven't done much off-roading with it yet because my son was too young for long trips. Now he's two and he loves to go off-road, the rougher the better, just keeps laughing all the way. From his seat in the Defender he's got a good view, and he loves the cargo area.

    Thanks for your input guys.

    The fuel lines are a sod to reconnect. Otherwise access is the only issue.

    For fuel pump inspection hole see Fuel Pump Inspection Panel - Mulgo Pty Ltd - Australia

    It's advisable to replace the rubber gasket/ O ring seal whenever the pump has been removed.
    I made up a 'special tool' to make R & R easier - see pic below.

    Best way to increase pump life it to not run tank low often..

    Keeping it over 1/3 when used urban helps lifespan (applies to all in tank vehicles)

    1. "Fit an access door to the pump on the cargo area."
    2. "The fuel lines are a sod to reconnect. Otherwise access is the only issue."
    3. "It's advisable to replace the rubber gasket/ O ring."


    OK lets assume I have easy access to the pump, removed it , reconnected the fuel lines, replaced the rubber gasket, and reattached the new pump.

    I can imagine there will be air pockets in the line.
    Will it be as simple as restarting the engine and probably after a few coughs and spatters the engine will run normally or is there anything else to be considered before restarting the engine ?
