Radium Engineering Fuel Cell Vent Kit - 12AN | Universal (20-0484-12)

Dry break refueling dumps fuel faster than a standard vent can exhale.

Quick-fill systems move enormous volume in seconds, and the displaced air needs an exit sized to match. The Radium Engineering Fuel Cell Vent Kit, 12AN is that high flow exit: typically used for quick-fill systems that commonly use a dry break and dump can, it includes an air filter, 6 feet (1.8m) of 3/4" ID fuel vent hose, and adapter fittings. The kit requires a 12AN male vent fitting, and pairs with the Radium 20-0462 quick fill DSV (12AN ORB to 12AN male).

What You'll Feel

• Dump can fills at full speed, with displaced air escaping as fast as fuel enters
• No burping, blowback, or geysering at the dry break during pit-stop refueling
• Filtered air returning to the cell as the race consumes the load
• A complete high flow vent installation from one kit

Features

• High flow venting for quick-fill systems using dry breaks and dump cans
• Includes air filter, 6ft (1.8m) of 3/4" ID fuel vent hose, and adapter fittings
• Requires a 12AN male vent fitting
• Pairs with the Radium 20-0462 DSV, 12AN ORB to 12AN male, quick fill

The Details

Radium's vent routing rules prevent the classic failures and are worth following exactly: from the fuel cell, the hose must first run upward so any captured fuel drains back into the cell; after ascending, the line should briefly route toward the front of the vehicle so slosh cannot escape; vertical loops act as a makeshift expansion chamber letting air out while fuel drops to the loop bottoms; overall vertical height should be at least 12", and for remote fill applications the loops must sit higher than the fill point. The vent is half the quick-fill equation, since a dry break can only pour as fast as the cell can exhale, and undersized venting is the usual culprit when dump can fills slow to a dribble. Standard-fill systems without dry breaks are better served by the 8AN version, keeping hose bulk down where the flow never demands 3/4" ID.
