I’ve done extensive testing of fuel components and still no luck, the rail pressure fluctuates at idle from 9500psi-5900psi while command pressure is 7200psi. Once you shut it off it will maintain rail pressure but it’s up from anywhere from 8500psi to 10500psi while command is still 7200psi.
When driving in high rpm the rail pressure gets to 42000psi and you back off the throttle and the rail will just hold that high pressure anywhere between 27000psi to 42000psi while command is right down around 7200psi
...

There is only one way to test the fuel rail for leaks.. and it is not at 7200 psi.. or at idle pressures. Many of the internal fuel system leaks will not show up at this low of pressures.

It has to be done exactly like this video shows ... at 29,000+ psi..
