Fuel and intake system

Removing and refitting thefuel tank
1. Remove the driver's seat.
2. If the fuel level in the tank is higher than
the suction line:
Clamp together the suction line (16) with
self-locking pliers or a hand vice.
3. Release the suction line from the feed
pump and plug it with a 10 mm plug or
bolt. If the fuel level is lower, the suction
line can be released from the tank.
4. Separate the return line (17) on the joint
nipple behind the radiator.
5. Remove the attaching plate (4) for the
tank and lift off the tank.
6. Check the rubber pads (2) for the tank
and then assemble the fuel tank in the
reverse order.
Measuring the feed pressure
See Perkins service instruction.
Connect the manometer to the vent screw on
the fuel filter holder, thread M6.
Bleeding the fuel system
If you have run out of fuel, the fuel system
must be bled. Facilitate bleeding by pumping
using a hand pump. Remove the fuel tank
filler cap and check the return fuel to the tank.
When bubble free fuel flows to the tank, the
engine can be started.
Carry out full bleeding as follows:
1. Loosen the bleed screw on the fuel filter
holder at least 1/2 a turn.
2. Pump using the hand pump until clean
fuel, without air bubbles, exits the drain
hole. Tighten the screw moderately.
3. Loosen the bleed screw on the injection
pump at least 1/2 a turn. Pump using the
hand pump until clean fuel, without air
bubbles, exits the drain hole. Tighten the
screw moderately.
4. Rotate the engine with the starter motor
for a maximum of 15 seconds. Wait
30 seconds before the next start
attempt.
