After the engine is started, it should run all the time. Fuel pressure is regulated via the fuel pressure regulator. The fuel pump relay should be under the hood in a relay box.

If you do that, it will run all the time unless you take power from a switched component. Also, if the vehicle is in an accident, the pump will continue running which could be a serious fire hazard. I wound not recommend it.

My 1985 Ford LTD LX H.O. 5.0L E.F.I. Has the inertia fuel cutoff switch and fuel pump relay in the trunk above the right wheel well, I'm not an 'expert' about the other models.
