Required is -
Dropping the fuel tank - not too difficult, even easier with a helper and his new blue healer puppy
1@ '05-'06 Dodge 2500\3500 Cummins fuel tank module with 9psi 5amp continuous duty fuel transfer (lift) pump
1 @ KJ I4\V6 fuel tank harness to match your year model - the connectors are different, as '05 has RW ABS, '06-'07 has 4w ABS
Or, any year - just transfer the black ground wire and green\red stripe or blue\red stripe power wire to your harness - the connector terminals are easily removed and transferred.

Lift pump ground is separate wire attached to the floorpan, bypassing the 14pin connector
The large bulkhead pass-thru in the floorpan is easily removed from beneath (after unbolting and moving the seat and carpet) by depressing four tabs on the in-cab circumference.
ECM-controlled power wiring is furnished to the connector under the left rear seat, oem-rated 10amp continuous duty - just plug'n'pump with only minor connector pin reconfiguration

The CP3 internal lift pump handles any required bypass chores, so fuel line connection is direct, no external bypass needed, no cutting\splicing, no hassle
Dodge designed the fuel module for the Bosch CP3 on the big Cummins engine, so the electric lift pump is draw-thru - engine will run as normal if in-tank pump fails.
The Dodge module, like the Jeep module, is designed for anti-slosh\anti-foam service, and has much better primary filtration than the Jeep version, which has NONE!
Fuel supply and return lines\fittings are identical, as the basic module assemblies are identical, with exception of the indexing tab.
Can assemble the Jeep upper to the Dodge lower if you use rubber tubing and hose clamps - doesn't appear to be necessary, at this time, as the offset is minor.
After install, do the }key ON - key OFF - key ON{ routine to enable the 25sec prime function which will bleed the air from the filter manager head - won't need the primer button for this, from this juncture on.
Close the bleeder valve, then do it again, checking for leaks from rear to front - air leaks too small to show up in the Jeep system will be readily evidenced at 9psi
System is not noisy - gotsta be very near the tank to hear the pump with 1/2 tank fuel.
Dodge fuel tank sender module is identical in form and function to the Jeep version - just plug'n'guage
Also pic'ed is the Cummins fuel manager head by Fleetguard - note the ease of fuel filter replacement with the top-loading assembly
It is side-feed from the tank, bottom-feed to the CP3 IP, uses the banjo-type fuel fittings
Has fuel heater, Water in Fuel: WIF drain is that yellow lever - fuel temp sensor can be clamped to the inlet
Plus, note the ease of fuel filter replacement with the top-loading assembly
Several models attach from the top, as this one - several attach from the front, like the Jeep head
This top-mount type can be drilled for front mounting - just transfer the hole-pattern from the Jeep version
**************************************************************************
Note the pic with the nylon vent-cap - that is your fuel tank breather vent, part of the filler system - note how it is at floorpan level - next time you're in water over the wheels, imagine the spatial relationship of that breather to the surface of the water, particularly if parked therein, as one member's avatar suggests
I replaced that 2" hose stub with a 2' rubber emissions hose to extend ours to the fuel filler area
Note also that the rear axle vent is at the same heighth - time to get it to higher ground, also - cannot at this juncture understand why Jeep "Trail-rated" these KJ's, except that the badge is explicit in omitting the "-and stream" qualification
