Input Requested from "Captive Refueling" HD Bus & Truck Fleet Managers;

I would appreciate your opinions regarding potential labor and cost saving benefits that may be derived from the development of an environmentally secure retrofit refueling system.

Recent White House activity has directed further reduction of "carbon emissions" from the Heavy Duty Bus and Truck markets beyond the current state of the art. The ATA has stated that diesel fuel consumption in these arenas exceeds 40 billion gallons annually. In the observations of this researcher; current diesel fuel dispensing technology does not capture the displaced fugitive vapors, nor prevent spills, at the point of refueling transfer. Our intention is to develop a method that addresses these issues while providing additional (and tangible) cost savings to organizations that may employ a fully developed system in the future.

The feature designs would include a closed-loop method of fuel transfer to eliminate spills, back-pressure spray & to capture 100% of fugitive vapors. The total containment of fluid and vapor of this proposed method holds the potential to significantly reduce the carbon foot print of fleet operations prior to combustion and exhaust.

Fuel volume is expected at 60 gpm (minimum) without fuel foaming or tank pressurization. The proposed design is a dual retrofit conversion for both; Island pump, and vehicle conversion. Vehicle installation would not interfere with OEM or existing retrofit refueling points. In addition, the completed system would include "hanger hardware" that simultaneously delivers; Diesel Fuel, DEF,Oil and Windshield Washer Solvent to respective holding tanks with a "single action" connection. The intended outcome of this multi-function design is to increase productivity of fleet vehicle throughput with higher efficiencies of labor and secure consumable fluid resources.

We are aware of "fuel only" retrofit systems in use for bus and rail; however, through our research we have not found similar high speed retrofit offerings for the multi-tanked (saddle) market for use within truck fleets. Our interest is in market validation for the need of this concept from the professional Fleet Managers perspective.

Thank you in advance for your comments and input.
