Multi-Pump Fuel Surge Tank, MPFST, Walbro GSS342, F90000267, F90000274, F9000285, AEM 50-1200, DW400, DW440, Bosch BR540, Ti Automotive E5LM, E85 Fuel Surge Tank, Radium Auto, 20-1440, 20-1441, 20-1442, 20-0443
Recently redesigned for 2024, the Radium Engineering MPFST is the perfect solution for high power vehicles experiencing fuel starvation during aggressive driving. Multiple high flowing fuel pumps can be used in the surge tank.
The outlet from the fuel pumps merge into a single outlet simplifying external plumbing. And because the compatible pumps utilize check valves, staging is permitted.
This MPFST allows the installation 1, 2, or 3 of the pumps listed below. It will include all necessary parts to install the pumps into the surge tank except for the pump(s) themselves.
SPECS & FEATURES
The fuel pump outlet port is 10AN ORB threaded and comes preinstalled with a 8AN male adapter fitting. The overflow, supply and return ports are all 8AN ORB threaded and come preinstalled with 6AN male adapter fittings. All of these fittings can be swapped out with different sizes (sold separately).
It is very crucial that a surge tank be plumbed exactly as listed below. Installations must not deter from this installation or it will cause function issues and premature parts failures.
- Stock tank pump outlet plumbs to the supply port on the MPFST
- Stock tank return inlet plumbs to the overflow port on the MPFST
- Pump outlet port on MPFST plumbs to the engine/fuel rail
- Return port on MPFST plumbs to return port on fuel pressure regulator
PUMP COMPATIBILITY
- Walbro GSS342
- AEM 50-1200
- Deatschwerks DW440
More compatible pumps are possible that are not listed here. Any pump that matches the same physical package can be installed as well.
- Deatschwerks DW400(2)
- Bosch BR540(1)(2)
NOTES
(1)This pump does not have an internal check valve. These pumps cannot be staged if used.
(2)Because of the physical pump size, 3 pumps can NOT be installed if using the optional fuel level switch.

NOTES
(1)This pump does not have an internal check valve. These pumps cannot be staged if used.
(2)To use this brushless pumps, the 13-1187 TRIPLE PUMP BASE must be purchased separately.

- Injector Dynamics BPC100
The E5LM pump requires a brushless pump controller. This pump is used in many different kits with varying controllers such as the ones listed above, and many others not listed.
FUEL LEVEL SWITCH, WITH OR WITHOUT DIAGNOSTIC INDICATOR
The Multi-Pump Fuel Surge Tank comes standard with a 2AN ORB plug in the level switch port. When the plug is unscrewed, this 1/8" NPT fuel level switch can be installed from underneath.
When fuel level in the MPFST drops by 20% or more, a switched signal can illuminate the diagnostic indicator, or it be sent to a unit such as a dashboard mounted indicator or programmable ECU input for safety purposes.
The level switch is constructed of corrosion resistant stainless steel compatible with all fuel types. It includes 24" long, 20AWG flying leads. Polarity can easily be reversed by removing the E-clip and flipping the float. Apply PTFE thread sealant to the tapered 1/8" NPT threads when installing.
NOTE: The level switch is not compatible with 3 Bosch BR540 or 3 Deatschwerks DW400 pumps. These fuel pumps are too big, so only two can be installed with the switch.
