Pretty simple.

use the stock fuel pump feed to feed the control on the relay or Relay's.Have the relay's feed both pumps.Ground the main pump relay,the second (boost)pump,have the ground go to the hobbs switch-then the other side of the hobbs goes to ground.

Make sure you use 2 seperate feeds to fedd the relays.

Also make sure you have a one way check valve at your second pump.
