A little background may be required -
You may have noticed the tremendous revolution that has taken place on the dragstrips and other motorsports arenas across the nation and around the world: Diesel engines rock!
And with the simplest of modifications, Diesel engines rule!
Yer grampaw's Diesels, these ain't!!
The relatively small Cummins 5.9L turboDiesel exits the factory in a state of tune easily producing factory spec'ed 350hp and 560ftlbs torque - with very slight alteration, a simple ECM reflash, it will easily and reliably produce 500hp and ~800ftlbs torque, all the while remaining docile and tractable, easily driven on the street and returning excellent fuel economy.
The late factory fuel supply system, an order of magnitude improved over previous versions, will supply fuel to meet that demand.
That ain't the wall, tho - add a few more mods and you're looking at 960hp and ~1200ftlbs torque - few more and yer lookin at 1200hp and ~1800ftlbs torque - all from that little 360cuin 6cyl engine - ain't no gasser (patooie!) even comes close!
However, the excellent oem fuel supply has hit it's limit at the 500hp level, to which problem racers began bypassing the oem system in favor of external high output lift pump systems, to which the aftermarket has responded with many variants, all of which have resulted in a problem with fuel supply vs fuel level.
The simple tubing drop, where the tank is drilled and a piece of larger diameter pvc tubing is inserted for increased fuel pickup as required to feed the external pump\filter system, draws air when the fuel is sloshing at 1/4-tank levels, even moreso below that, where the fuel naturally foams and bubbles when sloshed around.
Enter the Jeep fuel module, identical to the Dodge except pumpless - it is specifically designed to prevent the foaming and aeration which is problematical with Diesel fuel systems, particularly when the fuel is at low levels in the tank.
I knew about their lift pump module - it solves our problem - and I knew about our anti-slosh module, so I figgered our module could solve that problem for them - and it does, and being ABS\PVC can be easily modified for adequate fuel supply to meet increased performance demand.
Seems as tho them DCX engineers do know more than the street guys give them credit for, eh?
