|---- : : Mounting
the Pump : : ----
Select a convenient location near the existing fuel line closer
to the fuel tank, as indicated.
Drill two 6.35 mm (1/4") holes for mounting the pump, using the
pump base with grommets, as template. Note : The pump may be mounted
in any position; however, it is recommended that the outlet of the
pump be 15 deg. to 30 deg. above horizontal. This will allow any
vapour build up to easily pass through the pump.
Drill two more 6.35 mm (1/4") holes for fixing filter, using the
given filter bracket as template.
Ensure good ground contact by thoroughly cleaning the surface on
the vehicle's body work, where the fuel pump ground terminal is
Firmly secure the pump using the bolts, spring washers, plate washers
and nuts, supplied.
Install the fuel line and filter prior to mounting of the pump.
Connect fuel line from tank to inlet side of the filter and connect
outlet side of pump to carburettor line with flexible tube as shown
---- : : Precautions
: : ----
damage to the pump - check the voltage of the battery (working range
is 10 to 15 volts).
Do not mount the fuel
pump in the engine compartment, near exhaust or luggage compartment
Do not mount the fuel
pump at a position which is more than 45 cm (18 degree) above the
bottom level of the fuel tank.
To save the fuel pump
from wear due to dust / rust particles in petrol, the filter provided
should be connected before the inlet of the pump. Change the filter
once every 8000 km. or earlier depending on the working environment.
---- : : Electrical Connections : : ----
good quality 5mm auto cable wire for connections. Approximate requirement
will be 4 meters.
Connect the red power lead from fuel pump
to common terminal of ignition switch.
Ground the back lead of the fuel pump.
---- : : Bypasing the Mechanical Fuel
Pump : : ----
fuel lines from mechanical pump.
Connect the above fuel lines together using
suitable adapters / flexible tube provided, so that fuel is fed
to the carburettor.
Inlet and outlet of the disconnected mechanical
fuel pump may now connected to one another using a single flexible
---- : : Fault Diagnosis : : ----
Pump is not operating - check for proper
connections and earthing.
Pump is running but not delivering fuel -
check fuel line for bends / sharp corners (or) loose connections
and correct if necessary.
The outlet line must be opened to atmosphere
to allow the air in the system to escape and fuel to fill the line,
before connecting to carburettor.
Start engine and check for :
1. Air (or) fuel leak in line and fittings.
2. Kinked or clogged lines.
3. Carburetor flooding - (check for needle valve and float system)
