TEXT: Dear Mr. Trentacoste:

The Wiggins Connectors Division of IMO Delaval is working with the Automation R&D Group of United Parcel Service to develop a rapid fueling system for their truck fleet.

The concept is to retrofit the existing fuel tanks to accommodate a dry break quick disconnect fitting. The mating half of this fitting is attached to a standard dispensing nozzle. The vacuum sensing line runs coaxilly through the entire assembly.

At this point it is agreed that we should proceed with a test installation at a small UPS distribution center. The question that arises is what do we need in the way of approvals or sanctions to run a testing program.

We realize that later once the design has been groomed and before it is marketed formal testing and approval is required.

I have discussed this situation briefly with Bob Hagen and as suggested I am enclosing some system drawings of what we are proposing.

After you have had an opportunity to review this information I would appreciate your advice as to what steps should be taken to proceed.

Sincerely,
