Wife drives a 2007 Chrysler Pacifica 4.0 with 147K miles, original owner. Planning on doing proactive maintenance on it this spring to replace some things that are likely on borrowed time (original equipment). This is an investment in my wife not breaking down and getting stranded and, related, my general wellbeing and happiness.
One of them is the fuel pump. When I look up parts, I see a primary and secondary pump listed. To my knowledge, I've never owned a car with two pumps before. Is one a back-up? Do they work in tandem? Do I need to replace both?
This car was built when Daimler owned Chrysler and it has some Mercedes-style components and I wonder if this is another example.
This is a blind spot for me. Thanks a lot.
