Parts List
The steel fuel tank is located inside the trunk and mounted across the vehicle behind the passenger compartment bulkhead.
The fuel tank is held in posi tion by two retaining straps fi tted to body-mounted brackets.
The fuel tank has an integral non-adjustable fill er pipe and integral breather and vapor pipework.
A single fuel pump is mounted inside the tank on vehicles with normally aspirated engines. For vehicles with supercharged
engines, two pumps are fitted in the tank. Fuel is drawn by the pump(s) from the fuel tank and supplied via the fuel lines
and 70 micron filter to the fuel rails.

Tape Application
Apply a suitable length of 3M "Fine Line Striping Tape" to the panel. Having suitably applied the tape, which is slit into 8
strips, each 3mm wide, the appr opriate strip may then be peeled away to expose the lacquer coat below (Refer to
Application of Striping Tape Drawing). The paint may then be applied by hand brush or a suitable air-brush. The remaining
tape provides masking during paint applicat ion and drying. Careful positioning of the masking tape is necessary, particularly
when the repair is confined to a single panel and the newly painted coachline mu st conform to coachlines on adjacent
panels.
Where it is necessary to match an existing 1.5mm coachline, two tec hniques are available:
Proceed as above, to expose a 3mm strip of lacquer coat. Using either a standard masking tape, or a 3M "Fine Line Masking
Tape" applied over the striping tape, reduce the width of the exposed strip to 1.5mm.
Use a suitable combination of standard mask ing tape, together with 3M "Fine Line Striping Tape" if desired, to achieve an
unmasked strip 1.5mm wide in the correct position on the panel.
After application of the tape, use a fine-g rit wet-and-dry paper to lightly 'flat' the exposed surface, before application of
paint.
