The fuel filter is located between the brake booster/master cylinder and the air filter housing. The air ducting from the air filter housing to the the intake manifold needs to be removed. The top banjo bolt head size is 17mm, the filter is secured to the chassis leg with two
bolts that have a 10mm head size, but the the fuel line at the bottom of the fuel filter is held in place by a difficult to get at 14mm fitting that may be tight and is easily damaged. Before attempting replacement see if you can loosen this first from under neath the car, behind the drivers wheel, if you can't loosen this don't go any further! If you are still determined by a 14mm flare wrench.
