Radium: Triple Pump Base, 12mm Inlet Brushless Pumps
Radium Engineering uses a fuel pump strainer compatible with 1-3 pumps in many products. These are found in fuel hangers such as: MK4 Supra, FD3S RX-7, Civic Type-R, Early Nissan, R32 GT-R, 08-17 GM, etc. as well as universal products such as FCST-X, MPFST, MPFST-R, etc. The provided fuel pump base with those products are compatible with many brands including Bosch, Denso, Ti Automotive, Walbro, etc.
This 13-1187 fuel filter base adapter (shown below) permits the use a select amount of high flowing brushless fuel pumps that are made in China.
These pumps have the same ID inlet as the aforementioned pumps. However, the die casted OD of their inlet is slightly larger. This prevents a press-fit for proper mounting and filtration when using a Radium fuel pump strainer.
