Checking fuel tank ventilation
It is vitally important for the ventilation hose not to be
clogged, see Fig. page 200-3. If this hose is clogged, the
fuel pump will be unable to suck the fuel along or else
the tank can get sucked together and collapse. Check, there-
fore, that the hose is not clogged up with dirt, etc., and
make sure that it does not get jammed or squeezed in
course of removal or assembly work.
Fuel level transmitter
The fuel level transmitter consists of a float which, via an
arm and a switch, actuates the fuel gage. When the fuel
tank contains less than 1 3/4 US gals. (7 lit.) of gasoline,
a red warning light in the fuel gage comes on. The fuel
level transmitter is located on too of the fuel tank.
Removal
1. Remove the roll bar, see Chapter 8.
2. Remove the sheath ing from the transverse partition,
thus providing access to the fuel level transmitter
through the hole above the transverse partition.
THE FUEL LEVEL TRANSMITTER IS ACCESSIBLE
THROUGH A HOLE ABOVE THE TANK
Reassembly takes place in the reverse order.
Connect the electric cables as follows:
Brown cable to "W"
Gray cable to "G"
Black cable to earth.
Fuel lines
The fuel lines consist of the following parts:
The front pipe, mounted on the floor of the engine
compartment.
The rear pipe, which is mounted on the floor inside the
passenger compartment.
Both pipes are interconnected by a jointing hose in front
of the dash panel.
NOTE
The pipe must on no account be jointed inside the
passenger compartment.
Removal of fuel pipes
A. Front part
1. Disconnect the battery earth cable from the battery.
Jack up the front part of the car so that no fuel can
flow through the pipe.
2. Remove the starter motor.
Drain the fuel tank by disconnecting the lower hose
of the fuel pump. Loosen the pipe from the connection
at the fuel tank.
3. Undo the clamps on the right and left sides of the
motor. There are two clamps on each side.
4. Undo the clamp on the joint and pull out the jointing
hose. If necessary, remove the right front wheel and
right tie rod to provide better accessibility.
B. Rear part
1. Take out the right seat, the floor mats and wallboard
panels. R emove the transmission casing and the right
pedal plate.
2. Drain the fuel tank by loosening the lower hose of
the fuel pump. Loosen the pipe from the connection
at the fuel tank.
3. Remove the plate washer mounted in front of the
gear housing. Cut the pipe off at suitable points so
that it can be removed.
