Usage examples of fuelers.

I turned and watched as two workmen, probably fuelers, locked the exit door to the hangar and moved off toward the parking lot.

The other half were dressed as mechanics, fuelers, baggage handlers, and caterers--- the kind of people anyone would expect to see around parked aircraft.

You have four hours to grant permission for fuelers to land or we will burn the planet.

There were fuelers to carry extra batteries, back-up Intelligencers to replace lost craft, and repeaters that fell behind like a trail of breadcrumbs, carrying the weak transmissions of the Intelligencers back to the payload module.
