In this 9 minute instructional video, Kent will explain how to test your fuel accumulator to determine whether or not it has failed internally. A failed accumulator will make your engine hard to start when hot. It will make your fuel pumps run noisy, and it can affect your fuel pressure enough that your engine will run poorly. As a bonus, he will also discuss issues with the fuel hoses and the filter screen inside the fuel tank. Want to see what is inside an accumulator? That is also included.
