Our electronic fuel priming pumps are a powerful upgrade for backup power systems prone to fuel pressure drop-offs.

Featuring a heavy duty internal check mechanism, they act as a reliable non-return barrier, once the pump pressurizes the line, the valve locks tight to stop the fuel column from draining back into the base tank. By keeping the diesel primed right at the injection pump inlet, this system eliminates the harmful air pockets that cause rough idling or sudden stalling during automated load testing.

Low-grade aftermarket pumps often feature weak internal seals that quickly degrade when exposed to low-sulphur diesel, leading to internal leaks and pressure loss. Sourcing genuine factory units ensures that your threading, electrical insulation, and precise flow ratings align perfectly with your automated control panel's starting sequence.

The Generator King stocks fully certified fuel delivery components alongside original electronic relays, digital controllers, and automatic transfer switches (ATS) to give your equipment total protection.
