As I mentioned here-

The screw was loose when I lifted the plastic cover off. Does anyone know-

What it does?

How it does it?

Where it should be set?

Its called a Fuel Pulsation Damper. Used to smooth out the fuel pressure at the fuel rail. The pressure regulator is in the tank with pump.

Not sure what adjusting the screw does, but I know when there is pressure in the system the screw pops up (like pictured, gives an indication that there is pressure)

Thanks for that- one more piece of the jigsaw!

I suppose it damps out the pulsations from the fuel pump, the diaphram must work up and down against its spring.

I'll leave it loose unless someone has a better idea.
