Thats what I did with my holley HP 150. I wired a relay to +IGN and put a 20 amp fuse to the + post in the fuse box and wired the lift pump to the relay and grounded the pump to the frame at the pump.

Thats what I did, Also added a oil pressure sensor for saftey (no pressure = open circuit) to ground the relay. Pump wont start till oil presure goes above 7.5psi but never had any starting problems before fitting pump anyway.
