Fuel pressure dumper (1 Viewer)

I found the dumper with the completely unscrewed screw held by the plastic cover.
is it possible to put it back?

“Damper”

Never tried taking one apart. But that might just be a cover for the spring.

could someone please measure the depth of the membrane?
I want to adjust the screw
Thank you

I remember reading somewhere that the screw is supposed to sit flush when there's no pressure in the fuel rail, and slightly raised when there is pressure, making for a quick and easy way to check if there's fuel pressure in the system. So if you have the FPD out, I would just turn the screw in until it's flush, and then maybe a smidge more? Maybe with some locktite to keep it in place?

Or, just replace the whole unit. They're not expensive.

For me €180 is a lot of money, if it's possible I'll fix it.
