CAUTION
Failure to prime any new (dry) fuel filter can cause severe engine damage due to dry starting the engine. Please refer to the priming
procedure and follow it carefully after installing new filter cartridges and before starting the engine.
CAUTION
To prevent damage to the fuel filter element, keep it in its original packaging until you are ready to install it.
