Could be the other fuel pump, when one goes the other in line often fails too! Sad Range Rover-less at the moment - Pining!

Something not re-fitted correctly and starving the SC of fuel....

Did they clean/replace the fuel filter?

You have two pumps in your tank, one is the main sender (supplies your engine and fuel gauge) the other one (smaller one) equalises the fuel on either side of the tank...

Think of it like saddle bags on a horse, the small pump is meant to keep the fuel equal on both sides of the tank and when it fails you end up with a 1/4 tank on one side and nothing on the other...

Sometimes it makes sense to check the visual condition and change the lot (both pumps and pipes as a unit) if your keeping the car long term... If you can, check what crap is in the bottom of your tank when they are being changed. They dont like being run on cheap crappy fuel! Tesco's, Asda etc etc may be a little cheaper day to day but i liken their fuel to junk food. The supermarkets tend to buy fuel from anywhere and everywhere and believe it or not the bottom of the suppliers tanks are a cheaper purchase for them and offen mixed into theirs... Therefore the cheaper day to day fill ups cost you in the end with poor economy and mechanical failures...

Its not just the SC that suffers with these pumps, i have a TD6 here (arrived on an AA truck Tuesday afternoon) with the 1/4 tank syndrome too...


Craig Thumbs Up


Sorry to dredge up a classic article but can someone tell me if the jet pump is part of the main in tank pump or are they separate components? Also do the fuel pump get weak with time? It doesn’t seem to keep up with fuel delivery at full tilt?
