TITLE :

Replacement of fuel filler neck gasket and bolts

DOCUMENT # :

11 A 016

SITUATION :

PROCEDURE :

Quality Engineering at McLaren Automotive have updated the
fuel filler neck gasket along with three bolts securing the fuel filler
neck in place.

It is necessary to replace the fuel filler neck gasket and three
M6 x 16 bolts securing the fuel filler neck in place by following the
process outlined below:

Care point: Fuels are highly flammable and toxic if inhaled. Fuel vapours are explosive, invisible and spread out at
floor level. This vapour is poisonous when inhaled and has an anesthetising effect in high concentrations. Fuel can
damage the skin; for example skin is degreased when it comes into contact with gasoline fuel.

Keep fuel away from fire, open light or ignition sources.
Ensure the work place is adequately ventilated.
Never drain or pour fuels over assembly pits.
Store drained fuel in a suitable and sealed vessel.
Immediately eliminate any fuel that has flowed out.
Never conduct this work on a vehicle near open flames (e.g. if wielding is being performed in the
vicinity).

Care point: Ensure a side window is left open on the vehicle when leaving an electronic key in the car.
1. Leave vehicle unlocked with the fuel filler flap open and the electronic key inside of the vehicle.
2. Please refer to A-RM-02A04-04-009 - Lift vehicle on lifting platform.

REMOVAL :
1. Please refer to A-RM-03B03-01-001 - Remove/Install wheel - left rear
2. Please refer to A-RM-02A02-03-001 - Remove/install wheel arch liner – left rear.
3. Using a small flat screwdriver loosen and remove 37.6mm Oetiker clip on fuel filler neck. Unplug the fuel filler

connected (4).

7. In order to remove the earth strap wire McLaren Automotive recommend the connection should be unclipped from
the underneath of the bodyside rear panel (5) with the solenoid loom unplugged (6). This will allow more length on
the earth strap when lifting the filler neck to unclip. The fuel filler neck can then be removed completely.
