About this pump
The high-pressure pump raises fuel to the pressure injection demands, and on mechanical engines it also meters and times the delivery to each cylinder. It is a precision machine, and the fuel passing through it is the only lubricant its internals ever get.
That is why these pumps fail. Water in the fuel breaks down the lubricating film and corrodes the plunger and barrel. Abrasive dirt scores those same surfaces until the pump can no longer build or hold pressure. Running a tank dry can do the damage in seconds. The result is hard starting, low power and rough running.
Before condemning a pump, rule out the cheap causes first. A blocked filter, a collapsing suction hose or a failing feed pump will starve the injection pump and produce very similar symptoms. When you fit a new pump, find the cause of the old failure, renew every fuel filter, drain the water separator, and check the injectors for debris. Full guidance is on our high-pressure fuel pumps page.
