I have completely replaced all of the fuel injection components in my '75. Car runs great now. The fuel pump was not replaced and I don't know how old it is. Should I replace it too or leave it alone. It hasn't given me any problems so far. I'm taking a very long road trip to the West Coast from MI next month and don't want any problems. Thoughts?

I wouldn't replace it. Keep a spare in the trunk just in case.
