20-0693-00 FCST, PUMPS NOT INCLUDED, BRUSHLESS TI AUTOMOTIVE E5LM
The 20-0693-00 Fuel Cell Surge Tank is only available without pumps included. It is designed to use one or two Ti Automotive E5LM brushess fuel pumps inside the surge tank. A standard brushed pump is used as a lift pump.

The lift pump electrical and plumbing is set to be compatible with Walbro F90000267/274/285/295 fuel pumps. Radium Engineering recommends the Walbro F90000295 as a lift pump for maximum flow with a 14-0143 Filter Sock. Filter socks are required for all pumps. 

So this FCST includes two 20-0598 fuel pump outlet adapter. Because the 2 surge tank pumps merge into a single outlet collector, these high flow 1-way valves permit multiple pumps to be staged without backflow.
