Mobile fueling - also known as fleet fueling- is the practice of filling fuel tanks of vehicles from tank trucks.   This fueling takes place where the tank trucks are driven to the yards or sites where the vehicles to be fueled are kept when they are not in use.  Mobile fuelers were limited to dispensing diesel only since Stage II Vapor Recovery is required in most states for gasoline fueling.

Hill-Vac is a Stage II Vapor Recovery System that uses a 50 foot or 75 foot coax vapor recovery hose.  It is stored on a retractable reel and uses an ORVR vapor nozzle.  The Hill-Vac system has been under testing by the California Air Resources Board (CARB) for the past year.  It has exceeded the 95 percent recovery efficiency standards established by CARB.  Click Here to take a look at the Executive Order number is G-70-193. (Dated 12/9/99)   

The Hill-Vac system is currently operating on Mobile Fueling Trucks at Logan Airport in Boston, Massachusetts; Trans World Airlines at Los Angeles LAX; AirFlight, Inc. in Long Beach; Southern California Edison in Pomona; and GTE in Ventura.

The Hill-Vac Vapor Recovery System was developed to comply with CARB's Rule 461.   Rule 461 applies to the transfer of gasoline from any tank truck or mobile fueler into any motor vehicle fuel tank.  CARB adopted Rule 461 in 1976 and amended it in 1995.  Until the Hill-Vac system was developed, there was no means for the vapors to be recovered while wet hose fueling.

When the gasoline is transferred into the vehicle gasoline tank, the vapor recovery system must be capable of recovering or processing displaced gasoline vapors to an efficiency of 95 percent or greater.  Gasoline vapors have been linked to cancer and other respiratory ailments.
