Since 2015, Radium Engineering has been using a triple pump strainer in many fuel hangers: MK4 Supra, FD3S RX-7, Civic Type-R, Early Nissan, R32 GT-R, 08-17 GM, etc. It is also found in universal products: FCST-X, MPFST, MPFST-R, etc. The standard triple pump base included with those products is compatible with various fuel pump brands: Bosch, Unisia JECS, Ti Automotive, Walbro 13-1187 PUMP COMPATIBILITY Protec 11928 Fuelab 49614 Deatchwerks DW810 The 13-1187 triple pump base permits the use of a some high flowing aftermarket brushless fuel pumps: the 3-wire Protec/Fuelab pump and the 4-wire Deatschwerks DW810 pump Because the 12mm die-casted inlet (OD) on these pumps is slightly larger, the standard Radium triple pump base was not suitable for mounting and filtration. The press-fit is now compatible with the Radium 13-1187 Triple Pump Base, 12mm Inlet Brushless Pumps. CONSTRUCTION Aluminum, 6061 T6  Clear Anodized Type-II NOTES: This part is ONLY compatible with triple-pump Radium Engineering products. This part does NOT include the lower mounted stainless steel strainer. This must be reused from the existing triple pump base. The compatible pumps have the same inlet ID as the Bosch, Denso, Ti Automotive, Walbro fuel pumps, but a different OD. The Deatschwerks DW440 (not the DW810) brushless pump is of genuine OEM quality made by Bosch Motorsports and are compatible with the original Radium Engineering "11mm inlet" fuel pump strainer. Do NOT buy this 13-1187 triple pump base for the DW440 brushless pump. To avoid purchasing extra parts, select a Radium product compatible with Walbro F900002XX pumps. These pumps have the same outlet diameter thus sharing the same clamps and tubing. Instruction PDF
