Product Overview
A worn feed pump can allow fuel drain-back, make hand priming ineffective or starve the injection pump under load, causing hard starts and power loss that can look like an injection-pump problem.
Replacing the pump restores low-pressure fuel delivery and the manual priming function when the lines, filters and tank pickup are known to be clear.
