Fuel Pump: Description and Operation

PURPOSE
Provide high pressure fuel to injection system.

OPERATION
To ensure adequate supply, pump circulates more than the required maximum fuel amount at a higher than required pressure. While engine is running, pump runs constantly. Fuel delivery system is a loop, with excess fuel pressure and volume routed back to the tank.

CONSTRUCTION
High pressure, (in-tank) impeller type. Pump is installed as part of the in-tank fuel gauge unit and has a filter screen attached to its inlet to remove larger particle contaminants.
