The PO relocated the pump on my 74 (3 port Bosch) to the steering rack location. I think he used the AA kit to do it (found instructions in the documents he gave me with the car). It went south and I replaced it with a Walbro inline pump (similar to the two port Bosch pumps used on 75+ cars).
The only problem with wiring the pump to the fuse panel is that it's always hot. Could be a fire hazard in an accident. I believe with both D-Jet and L-Jet the pump will only run when the engine is running. In an accident you don't want the pump to continue running if the engine dies.
1.) You can pull switched power from the fuse panel
2.) D-Jet ..... pump runs for a couple of seconds when key is turned on ... then runs continuously when engine has started (signal from brain to pull the relay in).
3.) Don't have an L-jet but I believe the process is similar as the vane in the vane airflow unit moves.
4.) Alan doesn't have a relay board .... to make the fuel pump run continuosly from the relay board you have to jump pins in the relay or jump pins where the EFI harness hooks in. Either way it is switched power so it donna makea no difference ..... fuse panel or relay board.
5.) The real key is to get an oil pressure fuel switch (made by Holley). Allows power when in start postion and from normal source when engine is running, builds oil pressure and closes switch. Benefit .... if engine quits, power to fuel pump gets shut off.
