Filling the car from the bowser - Instructions

1.    Put the vapour line onto the car, and then the fuel line.

2.    Press the Car button, press the up or down arrows to get to the relevant car, after 3 second the display reverts to Net and will be zeroed. If you don’t have data logging this doesn’t matter, but we recommend that you Zero the Net.

3.    Put the toggle switch to To Car, and wait for the green light to come on.

4.    Press the pump button and the pump will begin moving fuel, this works on a dead man principle, you will need to keep the button pressed. 

5.    Adjust the speed control to the most advantageous speed, usually at about 12 o’clock for filling the car. If the unit cuts out you are making too much pressure, reduce the speed, reset the control unit and begin pumping again.

6.    The display will show the amount of fuel taken out of the bowser, NOT the amount of fuel that has been put into the car. If the fuel hose is empty it will fill before the car and this must be taken into account in any calculations. (e.g. 4 metres of -12 hose, plus the hoses in the bowser is something like 1kg of fuel, -10 hose is something like 0.6kg and -8 hose is 0.4kg.)

7.    When you have the correct amount of fuel in the car, centralise the toggle switch so that the pump cannot be activated by accident.  Remove the fuel line and then the vapour line. If you don’t have data logging make a note of what you have done.

Filling an FIA tower from the bowser

This is the same as for filling a car, but due to the height of the tower we suggest the use of the low pressure switch over-ride button which is on the underside of control box. This allows a faster pump into the tower with a higher pressure.

A single push of the switch toggles the low pressure switch off. 

When the control box is turned off the toggle drops and can be operated again if necessary.


Filling the bowser from a drum - Instructions

1.    Put the wand into the drum, connect the vapour line and then the fuel line.

2.    Turn the control box ON, the display will scroll through the software version and the settle time lockout. The display will read the net value, pressing the gross button will show you how much fuel is actually in the bowser. 

3.    Press the Car button and then the up or down arrow until you see drum, after 3 seconds the display returns to Net and is zeroed. If you don’t have data logging this doesn’t matter.

4.    Put the toggle switch into the To Bowser position and wait for the green light to come on. 

5.    Press the pump button and the pump will begin moving fuel, this works on a dead man principle, you will need to keep the button pressed. 

6.    Adjust the speed control to the most advantageous speed, usually at about 2 o’clock for bowser filling. Too fast and you will hear the pump begin to cavitate as the fuel vapourises in the lines due to sucking too hard. You cannot go too slowly but it can take a long time to fill the bowser.

7.    The display will show you how much fuel is in the tank, in the Gross mode it shows the actual amount in the bowser; in the net mode, if you have zeroed the display, it shows how much has been pumped in.

8.    If the bowser is full, the float switch cuts the pump and the LED goes out. The point at which this happens depends upon the specific gravity of the fuel, but it is at 100 litres or 170 litres depending on the size of your unit.

9.    When you have finished, take the fuel hose off first, and then the vapour line.


Checking the amount of fuel left in the car after a run.

If your car has a dip tube fitted, it is possible to empty the car fuel tank with the bowser. 

1.    Connect the vapour line and then the fuel line.

2.    Press the Car button and then the up or down arrow until you see the correct car, after 3 seconds the display returns to Net and is zeroed. If you don’t have data logging this doesn’t matter.

3.    Put the toggle switch into the To Bowser position and wait for the green light to come on. 

4.    Press the pump button and the pump will begin moving fuel.

5.    Adjust the speed control to the most advantageous speed, usually at about 1 o’clock for emptying the car. Too fast and you will hear the pump begin to cavitate as the fuel vapourises in the lines due to sucking too hard.

6.    The Net value shows how much fuel has been put into the bowser, NOT necessarily how much has been sucked out of the car; again, remember the fuel that can be in the hose. If the hose is full when you start and empty when you finish, the Net value will over-read compared to the amount sucked out of the car. 4 metres of -12 hose, plus the hoses in the bowser is something like 1kg of fuel, -10 hose is something like 0.6kg and -8 hose is 0.4kg.

7.    When you have finished, remove the fuel hose and then the vapour line.

Please note: The fuel pump is not positive displacement and therefore fuel will bleed past it if the unit is left connected. If the car is higher than the bowser the fuel will run out of the car; if the bowser is higher than the car it will flow into the car. For this reason we suggest that the bowser is only connected when necessary.
