just around the back side of the head with a universal fuel line and go directly into your transfer pump. just make sure if you build your own fuel line that the crimp fittings are as tight as you can get them. you dont want it to come a loose going down the road and you suck your injection pump and injector lines dry..5.9s are sometimes a bitch to get air out of sometimes.

I bent my stock gas fuel line halfway across the engine crossmember, and cut it at a straight section. going to put the return line from cummins engine to that.
and run a new suction line.
helps with aireation in the fuel if you return the fuel into the bottom of the tank, instead of splashing it.
