In short.....YesJames wrote:Could the fact that this fuel filter has not been changed (at 260000km) be causing bad fuel consumption? Thanks
At idle and low speed you wont notice it as much but when you are demanding full throttle the clogged filter restricts the full flow dropping the pressure and making the engine run lean, this causes you to drive for longer periods under full throttle and using more fuel as the engine does not deliver. Besides the extra consumption you can burn the valves as well due to a lean mixture.
Once you have found the offending part it is a relatively simple job to change just make sure that you tighten the fuel pipes properly and that there are no leaks afterwards. The new filter usually comes with new copper washers that go above and below the banjo bolts, that is about the only complication
