## Abstract

A fuel transport land vehicle formed by a tractor and a trailer carrying fuel in which the tractor has a plurality of axles all of which are steerable. The tractor and trailer are detachably coupled so that they remain along the same general longitudinal axis and sideways relative motion between the tractor and trailer is prevented. A pumping module is removably coupled to the vehicle and has disposed therein means for pumping, filtering and modulating the flow of fuel from the trailer.

## Claims

### Claim 1

A fuel transport land vehicle for dispensing jet fuel to an aircraft comprising
a tractor, a trailer having a tank for carrying jet fuel,
means for detachably coupling said tractor to said trailer,
pumping module means enclosed within a housing having disposed therein means for filtering said jet fuel and means for modulating the flow of said jet fuel from said tank, and
means for detachably securing said housing to said tractor whereby said pumping module means may be easily removed from said tractor upon malfunction of said pumping module means.

### Claim 2 (depends on 1)

The fuel transport land vehicle of claim 1 in which said housing is shaped in the form of a rectangular solid having walls and in which there is provided fastening devices for detachably securing a lower wall of said housing to a platform of said tractor.

### Claim 3 (depends on 2)

The fuel transport land vehicle of claim 2 in which there is provided quick disconnection means for fluidly coupling said pumping module means to said tank.

### Claim 4 (depends on 3)

The fuel transport land vehicle of claim 3 in which there is provided hose reel means disposed within said housing coupled to said modulating flow means for refueling the aircraft.

### Claim 5 (depends on 4)

The fuel transport land vehicle of claim 4 in which there is provided air line means disposed within said housing for providing dead man control.
