The plunger rises nevertheless even further, and at a selected second, the helical groove connects the spill port, from the rectangular groove to the fuel inside the higher A part of the plunger.
The plunger is pushed by a cam and tappet system at the bottom. It reciprocates while in the barrel. You will find as quite a few plungers as the volume of cylinders within the motor. The plunger has an oblong vertical groove.

In the event the Check out valve fails or is jammed open by fuel contamination, the maintain tension will leak down. If that transpires whilst the engine is chilly, the starter will crank a tiny bit longer although the fuel pump builds more than enough stress to get started on the motor.

The principle function of your fuel pump is to provide fuel on the engine at a consistent charge and pressure.
Maintain tension is checked concurrently as fuel procedure tension. Once the engine is switched off and the fuel pump stops functioning, fuel method strain will reduce marginally and afterwards hold constant for a minimum of 5 minutes.
