Dry cleaning solvent (E162) is
flammable and toxic. It can irritate
skin and cause burns. Use only in
well-ventilated area, away from heat
and open flame. In case of contact,
immediately flush skin or eyes with
water for at least 15 minutes. Get
medical attention for eyes.
1.
Remove barrier material and tape from hole (1)
in tank (2). Remove tape residue from tank. Use
dry cleaning solvent (E162) and cloths (E15).
Wear goggles to protect eyes. Wear gloves
(E186).
Do not puncture or scratch lining
of fuel tank. If lining is broken, fuel
penetrates and activates self-sealing
layers. Activated layers swell and trap
fuel. Activated green spongy material
also contaminates fuel system. This
makes it necessary to replace fuel
tank and flush fuel system.
2.
Position adapter plate (3), gasket (4), and valve
(5), with valve port (6) outboard, on bracket (7).
3.
Install four washers (8) and bolts (9).
