Conversion frame for fuel dispenser

1. A conversion frame assembly configured to secure a fuel dispenser to a concrete pad and direct leaked fuel from the fuel dispenser into a sump at least partially embedded in the concrete pad, the conversion frame assembly comprising:

a frame comprising:

a base plate having a fluid passageway; and

a splash lip extending upward from the base plate and around the fluid passageway; and

a drainage tray configured to be detachably coupled to the splash lip of the frame,

wherein, when the drainage tray is coupled to the splash lip of the frame, an upper surface of the drainage tray defines a weir sloping inward and downward from an upper end portion of the splash lip toward the fluid passageway in the base plate,

wherein, when the conversion frame assembly is installed, the drainage tray is separate from the sump, and

wherein the weir does not include an opening.

2. The conversion frame assembly of claim 1 , wherein the drainage tray comprises a different material than the frame.

3. The conversion frame assembly of claim 2 , wherein the drainage tray comprises plastic.

4. The conversion frame assembly of claim 2 , wherein the drainage tray comprises of thin sheet steel or fiber reinforced plastic.

5. The conversion frame assembly of claim 1 , wherein the base plate comprises a first plurality of openings configured to receive fasteners securing the frame to the concrete pad.

6. The conversion frame assembly of claim 5 , wherein the base plate comprises a second plurality of openings configured to receive fasteners securing the frame to the fuel dispenser.

7. The conversion frame assembly of claim 5 , further comprising a plurality of brackets configured to reinforce the frame at locations proximate to the first plurality of openings.

8. The conversion frame assembly of claim 1 , wherein the frame further comprises a standoff flange extending downward from the base plate.

9. A method of retrofitting an existing sump at least partially embedded in a concrete pad at a fueling station to contain leaks from a new fuel dispenser that is larger or smaller than an old dispenser for which the sump was designed, the method comprising:

installing a frame of a conversion frame assembly to the concrete pad around the sump, wherein the frame comprises a base plate having a fluid passageway, and a splash lip extending upward from the base plate and around the fluid passageway;

coupling a drainage tray of the conversion frame assembly to the splash lip of the frame, wherein:

when the drainage tray is coupled to the splash lip of the frame, an upper surface of the drainage tray defines a weir sloping inward and downward from an upper end portion of the splash lip toward the fluid passageway in the base plate,

wherein, when the conversion frame assembly is installed, the drainage tray is separate from the sump, and

wherein the weir does not include an opening; and

forming an opening in the drainage tray having a configuration based on a configuration of an open upper end of the sump.

10. The method of claim 9 , further comprising installing the new fuel dispenser to the frame of the conversion frame assembly.

11. The method of claim 9 , wherein the forming the opening in the drainage tray comprises cutting the opening in the drainage tray.

12. The method of claim 11 , wherein the drainage tray comprises plastic.

13. The method of claim 9 , further comprising removing a splash lip of the sump before the installing of the conversion frame assembly.
