Title: Fuel Valve part number help
Post by: jaylufc17 on October 16, 2022, 07:39:18 am
My fuel valve (believe it’s called this, the gold part that is taken out when changing cam follower) needs replacing. I can only find RS4 replacements.

Does anyone know the part number? I am running Stage 2 MK5 GTI DSG so not sure whether I need the RS4 one? I have the stock fuel pump fyi.

Can you add specifically what you seek please?
The HPFP has 'one' gold(brass) valve....the outlet valve (red circle).
It also has a fuel rail pressure regulator valve pointed to (yellow arrow).
The "RS4 - fuel rail pressure limiting valve" is attached to the fuel rail, is not mounted onto the HPFP, and it opens when there is too much fuel rail pressure....thereby relieving the rail of excess pressure, and returning fuel to the low pressure delivery side.

OK...they gave you the low pressure inlet (bamboo) fitting which goes on the bottom.

You need 06D 133 400 A;
