my tank is a 25l tub in the boot i carnt see any problems but there air coming from some where its not much very tiny bits
when its running the fuel pipe makes a tapping noise and moves and if you hold the rubber joints you can feal it pulsing is that right
and i dont think i can hear the turbo spolling up
i opened the air box it was full of leaves so i cleaned it and took out the filter then tried that but its the same
oh year my car is a range rover i only asked if the disco bit because its got a 200tdi in it thort it would be easyer that way
