The way I opened up my fuel system,
Was to butcher my old fuel module and plumb a 5/8in copper line into the fuel module to supply my pumps.The problem with this setup is when the tank runs below 1/2 a tank the pumps cavitate on heavy accelleration or hard braking.If I had it to to do over again I would have tried suppling a regular lift pump with Mopars new in tank pump.This way pressurizing the suction line would prevent cavitating to the regular lift pump.Diesel as well as gasoline does not behave well in a vacuum.That is why engineers have moved fuel pumps into the bottom of the tank.

From that point on, all the lines are stock. Does this sound right? Thanks again for the information
