Radium Engineering Fuel Surge Tank O-Ring Service Kit | Universal (20-0087)

A surge tank comes apart for pump service; its seals should not be the reason it goes back together twice.

The Radium Engineering Fuel Surge Tank O-Ring Service Kit is the refresh set for Radium FST assemblies: the replacement O-rings the tank uses at its sealing surfaces, ready for the pump swaps, cleanings, and teardowns a working surge tank accumulates. Fuel-compatible material, direct fit, and the difference between a service that ends dry and one that ends with a drip.

What You'll Feel

• Pump swaps and tank services finished with fresh seals instead of reused gambles
• A dry, confidence-inspiring reassembly every time the FST opens
• The right rings on hand before the tank is in pieces on the bench

Features

• Replacement O-ring set for Radium FST fuel surge tanks
• Fuel-compatible sealing material suited to gasoline and E85 duty
• Direct replacements for the tank's service seals

The Details

Surge tanks live a harder seal life than most components: the body opens for pump installation and every subsequent service, the O-rings cycle through fuel immersion and compression, and alcohol blends accelerate the aging of any seal that was marginal. Radium's guidance for O-rings applies at every step, with each ring lubricated using O-ring lube, petroleum jelly, or oil before assembly and inspected for nicks or flattening whenever the tank opens. Ordering this kit alongside a pump swap turns a maybe-reseal into a definitely-sealed job. Verify your FST model's fit before purchase.
