OVERVIEW
Dump cans are used in motorsports when quick refueling pit stops are essential. The main difference between a "dump can" and a common "fuel jug" is the vent architecture. For quick filling, air entering the can must replace the exiting fuel at the same rate. If not, a vacuum will create a flow restriction and produce a "gurgle" or "chug" effect. These Radium Engineering 6 gallon dump cans are designed with a large 1.675" OD vent tube that comes from the bottom minimizing refueling leaks and maximizing air flow for quick-filling. The vent tube can also be used for re-filling the dump can.
The dump cans are molded from a durable polymer safe for all fuel types (leaded gas, unleaded gas, diesel, AV gas, methanol, ethanol, E15, E85, etc.). The external rectangular shape was designed to match the fuel jug industry standard (9.5" x 9.5"). This allows for easy securing and storing with other fuel jugs. The integrated vent handle has finger grips for comfort. Other ergonomic features are molded into the dump can to make handling easier. The accurate graduation marks are molded in "US GALLONS" (shown below) on one side, and "LITERS" on the opposite side.

20-0697-00 QUICK FILL DUMP CAN, 6 GALLON, STANDARD FILLER
This dump can assembly has all the features mentioned above and is configured for "standard filling" (non-dry break). This is ideal for all types of motorsports.
This dump can features knurled aluminum pour and vent caps. The inner flow diameter of the stainless steel spout is maximized yet still compatible with all OEM fuel fillers.
For ergonomics, the anodized aluminum plug also features knurled machining.
The vent cap features 6 different fuel type indicators: (UNLEADED, LEADED, METHANOL, ETHANOL, PRE-MIXED, DIESEL). The small knob can be screwed into the appropriate threaded hole to mark the fuel type inside.
For slow controlled filling, the plastic flip cap (shown) can be simply unlatched. For quick filling, the entire vent cap can be unscrewed.
20-0697-01 QUICK FILL DUMP CAN, 6 GALLON, 1.5IN DRY BREAK
This dump can assembly includes a Radium Engineering dry break probe compatible with 1.5" dry break receptacles. As shown below, the short tube is clear for fuel fill monitoring.
Unlike the 20-0697-EDC (economy dump can) described below, this dump can features knurled aluminum pour and vent caps. And because these unscrew, filling the dump can is a quick efficient process.
As shown above, the vent cap features 6 different fuel type indicators: (UNLEADED, LEADED, METHANOL, ETHANOL, PRE-MIXED, DIESEL). The small knob can be screwed into the appropriate threaded hole to mark the fuel type inside. For quick filling with the dry break, the vent cap is removed for maximum air flow into the dump can.
NOTES:
1. The plastic pour spout can be cut to suit 2.5" and 3" dry breaks.
2. For maximum flow efficiency, the fuel tank (or fuel cell) should have a large vent (see Radium P/N: 20-0535).
20-0697-EDC QUICK FILL DUMP CAN, 6 GALLON, 1.5IN DRY BREAK
The "economy dump can" is a cost efficient option for pit crews that require numerous fuel cans for multiple vehicles. This dump can includes a Radium Engineering 1.5" dry break probe compatible with both direct and remote mount dry break receptacles. It features a silicone coupler with stainless steel clamps for securing the dry break. The rubber vent plug is simply removed using the stainless steel wing nut. 
NOTES:
1. The plastic pour spout can be cut to suit 2.5" and 3" dry breaks.
2. For maximum flow efficiency, the fuel tank (or fuel cell) should have a large vent (see Radium P/N: 20-0535).
3. The EDC is not compatible with the screw-on caps mentioned above as there are no external threads.
