OK so then in the first pic you can see a line come across the motor and bolts to the front of the head with a banjo bolt this comes from the fuel filter and theres one just like it on the other side. Then in the 2nd and 3rd pics whats the top gear do looks alot loike an HPOP to me with the lines coming out and screwing into the heads which in the last pic you can see where it comes out of the rail into a line and into the top of the injector and nowhere was this connected to the fuel system looks just about like the setups on the 7.3's but with stuff in a little different places. So if this is not the same style fuel system as the 7.3 and 6.0 what is all this stuff and whats it do?
