It can hold up to 3 surge tank pumps and 1 lift pump of the following. PUMP COMPATIBILITY- Walbro GSS342- AEM 50-1200- *Deatschwerks DW440*Use the electrical connector provided with the pumps. 20-1990-02This FCST-X is preassembled with 1 Walbro GSS342 lift pump and 2 Walbro GSS342 surge tank pumps. 20-1990-03This FCST-X is preassembled with 1 Walbro GSS342 lift pump and 3 Walbro GSS342 surge tank pumps. 20-1991-00This FCST-X does not include fuel pumps. It can hold up to 3 surge tank pumps and 1 lift pump of the following. NOTE: If using the optional fuel level switch inside the surge tank, only 2 surge tank pumps and 1 lift pump can be used. PUMP COMPATIBILITY- **Bosch BR540- *Deatschwerks DW400*Use the electrical connector provided with the pumps. For the lift pump, use the filter sock provided with the pump.**Because this pump does not include a built-in check valve, multiple surge pumps must be ran together (not staged). 20-1992-00This FCST-X does not include fuel pumps. It can hold up to 3 surge tank pumps and 1 lift pump of the following. PUMP COMPATIBILITY- Walbro F90000267- Walbro F90000274- Walbro F90000285- *Walbro F90000295*Because this pump does not include a built-in check valve, multiple surge pumps must be ran together (not staged). 20-1992-01This FCST-X is preassembled with 1 Walbro F90000274 lift pump and 1 Walbro F90000274 surge tank pump. 20-1992-02This FCST-X is preassembled with 1 Walbro F90000274 lift pump and 2 Walbro F90000274 surge tank pumps. 20-1992-03This FCST-X is preassembled with 1 Walbro F90000274 lift pump and 3 Walbro F90000274 surge tank pumps. 20-1993-00This FCST-X does not include fuel pumps. It can hold up to 2 surge tank pumps and 1 lift pump of the following. SURGE PUMP COMPATIBILITY- *Ti Automotive E5LM (check valves included)LIFT PUMP COMPATIBILITY- *Ti Automotive E5LM- **Walbro F90000267- **Walbro F90000274- **Walbro F90000285- **Walbro F90000295*This pump requires a brushless controller. These typically come standard when purchasing the pump. See Ti Automotive BKS1001.**For these pumps, it is recommended to use the Radium Engineering 14-0143 filter sock. 20-1995-00There are two 80u (micron) filters included for two 10AN (5/8") pickups. If using the provided 16AN (1") pickup, an external filter will need to be purchased. The surge tank can be configured to use any combination of the following:  SURGE TANK COMPATIBILITY- (1x) 10AN pickup (shown below) for an inline external pump or mechanical pump. - *(2x) 10AN pickups for an inline external pump and/or mechanical pump.- (1x) 16AN pickup for an inline external pump or mechanical pump.- *(1x) 16AN pickup and (1x) 10AN pickup (shown below) for an inline external pump and/or mechanical pump. *An electric pump can be used to prime a mechanical pump (for faster engine starting) when running 2 of the pickups. This FCST-X does not include a fuel pump for the lift pump. It is compatible with the following.
