Priming the System
Priming Procedure
There is no need to fill the system with fuel prior to startup. The diaphragm pump is self-priming. It is however very important
to prevent pump damage by slowly starting the pump with low air pressure values, between 20 to 30 PSI, especially if there
is no liquid in the pump. Once the complete system and hoses are primed and full of fuel, you can increase the air pressure
to achieve the desired flow rate.
An advantage of starting the process with low air pressure (and therefore low flow rate) is observing the liquid coming from
the bottom of tank to see if it is pumping water, debris, and/or fuel.
! IMPORTANT ! Never exceed 18”HG on vacuum gauge located before of pump.
