#20-000 FRD-2 3 PSI FUEL PUMP
&
#20-002 FRD-HD c/w REGULATOR FUEL PUMP
•
These are 12 volt DC pumps. The factory spring pressure for the #20-000 FRD-2
pump is set at 3 PSI (max 6 ft. lift).
•
The #20-002 FRD-HD pump has a stronger pressure spring that will draw the fuel
higher (max 15 ft. lift) but will need the regulator to adjust the pressure down to 3
PSI before the fuel goes to the oil metering valve.
•
You must use a fuel oil filter in your installation before the pump to keep debri
from plugging up the 3 check valves inside the pump.
•
When the oil metering valve (carburetor) is full and the line is up to pressure, the
pump will still “tick” but less frequent depending on the demand from the oil
metering valve. NOTE: Include the pump in a control circuit with a 3 amp fuse )
(16 awg wire) so you can turn it off when the heater/stove is not in use.
•
NOTE: If the power to the pump is shut off, the fuel could still flow through to
the pump by way of siphon. The flow of fuel should be turned off using the
shut-off valve near the heater/stove as well as the oil metering valve.
•
IMPORTANT! This pump must be installed as high as the oil metering valve (or
higher). This pump is a “pull” pump rather than a push pump, and must be
installed so that the fuel oil is pulled as high as the oil metering valve and gravity
feeds back down to the valve. Use a rubber backing as a washer to soften the
sound of the pump and use appropriate screws to fasten. If there is no fuel getting
to the oil metering valve, you may need the heavy duty pump # 20-002, or call /
email Dickinson for retrofitting a stronger pressure spring in your pump and
installing a pressure regulator # 20-003 between the pump and the valve
(converting a #20-000 FRD-2 pump to a #20-002 FRD-HD pump.
•
The pumps can be installed with fuel inlets and outlets up or down, however
mounting the pump with the fuel inlet on top (Note the fuel OUTLET is on the
end of the pump that has the wire connections and the 3 assembly screws), will
give the pump extra pressure and is easier to clean but will need to be primed the
first time only to remove air in the fuel line). There are 3 check valves in the
pump to prevent the back flow of fuel, so the pump should stay primed. If the
pump does not stay primed then 1 of the check valves in the pump needs cleaning.
To prime the pump disconnect the fuel line at the valve fuel inlet and pump fuel
into a container to remove all the air in the fuel lines. After a cup of fuel has been
pumped, reconnect fuel line to the valve.
•
The pump should be installed in a ventilated area and not near a hot exhaust.
•
Ground to negative battery (not recommended for gasoline).
•
To retrofit the pump to a higher pressure unscrew the 3 torxs screws (t-20) and
with twisting the lid back and forth, pull it straight back off. Note the pump
plunger, spring, check valve , and a very small amount of fuel will drop out if
