Hi Justin,......
about the electric fuel pump,....for what it's worth I installed one on my 41 Fargo,.....pump is out of a mid 80's Honda,.....no relay required,....when it's running it only clicks,......mounted it on the left front splash guard near the master cylinder,......been operating there for past 8 years or so.
Hope you found one that works for your application.
Cheers
Bob.
