The fuel rail valve is the one in the front of the rail right? I don’t think there is a way to check it only buying a new one am I correct?

It is easy to check to see if the rail pressure relief valve (the notorious valve to get leaky atg the front of the rail) is leaky.
just loosen/undo the banjo fitting on the end of it (it is a return line) and do a rail leak test. Not a drop of fuel should come out of the relief valve.
It is possible fuel leak from valve return line connected to fuel return manifold. Line need to be disconnected completely and moved away from valve head or use special tool to monitor only valve return line or block valve return line at fuel return manifold with 12mm bolt.
