Removing injection valves - Boxster S







1 - Removing passenger's seat
Remove the passenger's seat for better accessibility. Unscrew the four fastening screws for this purpose. Disconnect the electrical connections under the seat and take the seat out of the vehicle.







2 - Opening maintenance cover
Remove rear wall lining. Then remove the maintenance cover. Unscrew the seven hexagon-head bolts and the two fastening nuts for this purpose. Take the maintenance cover out of the vehicle.







3 - Removing fuel line on pressure regulator
Make sure to place a cloth beneath the screwed connection since fuel emerges when opening. Undo the fuel line from the vehicle interior (through the maintenance cover). Counter with a second open-ended wrench when doing this in order to prevent damage to the pressure regulator.







4 - Undoing fuel return line
Place a cloth beneath the screwed connection of the fuel return line. Undo the screwed connection of the fuel return line at the back end of the right ring pipe. Counter with an open-ended wrench to avoid damage.







5 - Unscrewing fastening screws
Unscrew the two fastening screws of the fuel ring pipe on the left and right of the intake system (diagram shows only one side of the ring pipe). Disconnect the electrical connections of the injection valves. To do this, press the metal spring on the plug and pull off the plug at the same time. Carefully lift the fuel ring pipe upwards out of the engine compartment. Undo the fastening screws on the intake distributor for this purpose.







6 - Removing injection valves
Push the fastening clips of the injection valve to do this. Then pull the injection valve concerned out of the fuel ring pipe. Do not use the old sealing rings again.
