In this video I'm demonstrated how to prime a centrifugal petrol water pump or a diesel water pump
Before starting up your water pump make sure that you fill water at the top of your gasoline/diesel water pump and usually the combustion water pump will come with water filler plug at the top, So you take out that cover and Start to pour water from the top until water comes out of the discharge hose
Once the crankcase is fully and water gets out of the discharge hose the priming process will be completed. You can also start by pour water along the suction hose until it's full of water then immediately dip that suction hose into the water
Start up your engine or switch on your water pump and wait for sometimes for the pump to pick up the water and Start pumping

If the pump didn't pump out water for long time let's say five minutes and water has not yet get out of the discharge hose something might be wrong with the priming process, make sure that the suction hose is well tighten to the water pump and no air gets inside the suction side of your pump

The purpose of priming the centrifugal pump is to remove any air that is inside the crankcase and suction hose as well

Don't remove the suction hose out of the water during pumping operations as that will destroy priming process by allowing air to enter the suction hose also make sure that the water level doesn't fall below the suction hose as that will also make water pump to run without pumping water
