Prime the pump and system
To prime the fuel pump and fuel lines (or for fuel pump test purposes), it is necessary to open the fuel solenoid shutoff
valve and run the fuel pump manually. For this purpose, use the
Test–Functions Menu
selection,
Fuel Pump Test
(Purge Fuel)
. This test opens the fuel valve and acts as a speed control for running the pump.
Note:
PRO engines have
internal solenoids so the valve function is irrelevant.
Before activating the purge pump mode, ALWAYS remove the fuel feed line connected to the
engine.
Pump Test / Purge Fuel allows the fuel pump to operate without the engine running. However, if
the fuel feed line is not removed from the engine during this procedure; it will become flooded with
fuel. When this occurs, the next engine start can become highly combustible!
Use the select menu key and select the
Test-Functions
menu.
Press the Change Value/Item key to run the pump. If you want to change the voltage the pump runs at, press either
the
◄
- or
►
+ while pressing the Change Value/Item key. It is best to lower the pump voltage back down to the 0.5V
default amount when finished.
The priming function on the PRO engines should typically only be used to fill the fuel lines after initial installation of
the engine. Make sure to stop the pump latest 2 seconds after the fuel has arrived on the input port of the engine,
otherwise engine will be flooded with fuel (this can lead to fire and/or malfunction).
In case the engine should be de-installed, it is possible to run the pump in reverse direction by selecting negative pump
values when priming the pump (via
◄
- key) .
It is also possible to directly switch between forward/reverse operation by pressing the “Set” button alone. Pressing
“Set” will toggle between positive (forward) and negative (reverse) pump voltage values.
Remember
when the
Select Menu
key is pressed and held, the
◄
- /
►
+
keys are used to select
another menu. When a desired menu is reached, release the
Select Menu
key, and your selection
becomes the currently displayed menu.
