Don't bother with the electric pump. A canister and check valve will be more than enough assuminig your civic did not leave the factory with them.
If you let off the gas for just a fraction of a second and allow the transmission to spin the engine with the throttle closed I would expect to see it develope at least 27in/Hg. If you could store that in a vacuum tank you will be all set to run vacuum assisted brakes.
The OEM may have found it cheaper to just fiddle with the ECU progeram to help run brakes insted of installing a tank and valve.
