Radium Fuel Vent Charcoal Canister | Universal (20-1828-08 / 20-1828-12 / 20-1828-00)

A vented fuel cell smells like a fuel cell. This is the part that fixes it, and the test data is not subtle.

The Radium Engineering fuel vent charcoal canister installs in-line with the fuel tank or cell vent and traps the vapour that would otherwise exit to atmosphere. Radium measured the vent exit with a combustible gas detector: without a canister the meter maxed out beyond 10,000 ppm, and with one fitted it read below 50 ppm, which is the detector's floor. Flow testing with a quick-fill dry break dump can showed negligible pressure drop, so the canister does not slow filling. Works with EFI and carbureted systems alike.

Choose Your Kit

• For 1/2in hose (20-1828-08): standard flow, pairs with the 20-0484-08 vent kit
• For 3/4in hose (20-1828-12): high flow, pairs with the 20-0484-12 vent kit, and a 3/4in air filter attaches directly to the barb
• Universal (20-1828-00): includes two 16AN ORB male to 10AN ORB female couplers for classic tanks running 1/4in, 5/16in, or 3/8in vent line

What You'll Feel

• No fuel smell in the garage, the trailer, or the paddock
• Fill speed unchanged, verified against a dry break dump can
• A rebuildable canister rather than a throwaway part
• Ports that work either direction, so mounting orientation is your choice

Features

• CNC machined 6061 aluminum, type-II anodized
• Vibratory-packed activated carbon inside a 150 micron strainer and anodized baffle, so no carbon debris escapes
• Two 16AN ORB (1-5/16in-12) female ports, usable interchangeably as inlet or outlet
• Two 4AN ORB (7/16in-20) drain ports at the base with preinstalled plugs
• Holds 5x the activated carbon of the compact canister, requiring less frequent service

The Details

The standard canister is the one to buy if you would rather service it rarely: it carries five times the carbon of the compact version, though both test below 50 ppm at the outlet. Carbon saturates with use rather than time, so recharge intervals depend on how the car is used; the 20-1828-SK service kit supplies fresh carbon and a new 150 micron strainer when efficiency drops.

Plumbing matters. A section of vent hose upstream of the air filter must sit higher than the fuel filler, and vent line loops are recommended to keep debris out of the fuel system. Mount the air filter at the rear of the car, away from the exhaust. Depending on mounting orientation, one of the two 4AN drain ports can take a petcock drain kit to remove any fuel that collects.

Kit Includes

• Charcoal canister with preassembled activated carbon, strainer, and baffle
• Two 16AN ORB male to 10AN ORB female couplers (universal kit only)
• Barb fittings sized to the selected hose (08 and 12 kits)
• Preinstalled 4AN drain port plugs
• NOT included: vent hose, air filter, and additional adapter fittings

Applications

• Universal, any EFI or carbureted fuel tank or competition fuel cell vent system
• Designed to work alongside Radium fuel cell vent kits

Important Notes

• The activated carbon requires periodic replacement; use the 20-1828-SK service kit
• Vent hose upstream of the air filter must be routed higher than the fuel filler
