If you've added on an aftermarket fuel system or other modifications on your 1994-1998 Ram 5.9L Cummins build, chances are you've noticed its efficiency isn't what it used to be. Aftermarket lift pumps can filter and keep up to a quarter tank of fuel in your rig, leaving a lot to be desired on any long hauls. Pick up an aftermarket fuel sump to get the most out of your fuel system so you can enjoy a longer stretch of the journey without having to constantly fill up.
