In typing my car make/model (2013 Mazda5 sport) into Amazon, Autozone, ect. a number of different fuel pumps appear for my car. Some are mechanical, which match the factory shape, size, connects and so on. However, a number of universal electrical pumps appear at the fraction of the mechanical pump prices. The electrical connections do not appear to be the same, but with some electrical work, they look like they could be adapted.
Here are some examples of the units I’m looking at:
My questions are:
Will the price reflect the reliability of the fuel pump? Is it worth even bothering with an electric pump? What is the major differences here and are there any downsides one should be aware of when going with an electric pump? Any other thoughts would be very help!
