I have a 2001 Ford Mustang that originally was V6 automatic, The car now has a 1997 4.6L Modular V8 with an aluminum crossover intake manifold and a 2004 TR3650 5-speed sn95 original transmission and I need to replace the fuel pump! I don’t know which one I need since my car is a Johnny Cash country song…
I would go with the 2001 fuel pump since the harness is already wired for it and mounting points may be different if you choose an older model year (also I’m pretty sure the 97 fuel pump looks completely different)
