Thanks for the reply GTP Dad, With doing some research I found out a couple things that might be of some use to others. First, to change the fuel pump and module you DO NOT have to drop the tank, there is an access panel under the back seat. Next, the fuel pump and the module are ONE assembly, there is a new mod to the system that will cost you an extra $42 at the dealer, some wiring upgrade tot he assembly. The Module contains check valves to hold the pressure, no regulator on the fuel rail it is ALL in the gas tank. If you have issues with your liberty Email me I have the diagnosic print out from JD. Hope this helps some one.
