For convenience and better cleaning, remove the two screws that hold the plate and get her out.

Now, with rags and solvent cleanse the plate itself and all the innards.

When installing the note on the side profile of the plate - it's asymmetric, does not make it the "upside down." The plate must lie in the plane of the pipe, rather than an edge.

It remains to set it in place. If necessary, use a new gasket, and in a pinch you can without sealing gaskets on its land. In some of the time, it was true.

Hello Mohamed!

May you more detailed describe your case?

Now it seems not enough fuel pressure at common rail.

It may cause by any reason of list below:

too high return fuel rate at injectors;

wear of high pressure pump (not enough performance);

and pressure regulator.

So, first You have to understand why the fuel pressure is not enough.

First of all I advice to test fuel injectors leak like on video:

If you injectors will have to high leak rate you have to replace or clean/repair it. If you can not find good specialist I advice to buy new injectors.
