Radium Engineering - Performance Fuel Systems & Universal Accessories

Since 2010, Radium Engineering has made its mark by designing and producing high‑performance aftermarket automotive components—specializing in fuel delivery, surge tanks, catch cans, pulse dampers, and coolant systems—all engineered in Clackamas, Oregon, with meticulous attention to fit and function. Built for both enthusiast street cars and hardcore race applications, their RA‑Series fuel bladders withstand all fuel types—from gasoline to E85 or methanol.

Radium’s surge tanks (single-, multi-pump) and FCST-X systems prevent fuel starvation under high‑G conditions, while their pulse dampers help maintain stable and safe fuel pressure. Backed by detailed installation guides and direct customer support from their U.S. facility, they ensure both reliability and ease of use for DIYers and professional builders.

Whether you're upgrading your fuel system, eliminating vapor lock, or optimizing performance on track, Radium Engineering delivers precision‑machined, race‑ready solutions that stand the test of time.
