LR3/Disco 3
The fuel filler pipe locates in a short flexible hose attached to the tank and is secured with worm drive clamps. The
canister breather pipe is routed alongside the fuel filler pipe and attaches to the canister with a quick release coupling.
A fourth pipe is also routed alongside the fuel filler pipe and provides air ventilation for the charcoal canister. On all petrol
vehicles, except NAS vehicles, the pipe is connected to the air pump port on the charcoal canister with a quick release
coupling and connects to an insect trap at the fuel filler head. On NAS vehicles fitted with a DMTL pump, the pipe
connects to the pump vent port and is also connected to a filter which is attached to the filler head.
A smaller pipe, which is not associated with the fuel system, is attached to the side of the fuel filler pipe. This pipe
connects to the rear differential and provides breathing for the differential case. The pipe terminates near the fuel filler
head.
