Call or Text (352) 722-5295Fuel sumps on the 2015-2016 Ford 6.7L Powerstroke
From the factory, fuel on the 6.7L Powerstroke leaves the tank for a frame-mounted Diesel Fuel Conditioning Module that holds the electric lift pump, a 10-micron primary filter and a water separator. A sump is not part of that factory setup. It is a fitting that mounts through the bottom of the tank and gives an aftermarket lift pump its own pickup at the low point, and some designs also bring return fuel back in through the same fitting. Tank size depends on wheelbase: Ford fit 26-gallon tanks to 137-, 142- and 156-inch-wheelbase diesel F-250 and F-350 trucks, and 37.5-gallon tanks to 158- and 172-inch wheelbases and every F-450.
Why supply matters on this engine
The CP4.2 high-pressure pump is fuel-lubricated, and running the tank low or out accelerates its wear. When a CP4.2 fails, its roller followers shed metal that can spread through the injectors, rails, lines, lift pump and tank. That is why the same guidance keeps coming up: do not run the tank low, add a lubricity additive at every fill, and let the lift pump run 5 to 10 seconds after the wait-to-start light before cranking. A sump does not change the CP4.2 itself. It is part of doing an aftermarket lift pump install properly.

Fitment notes
Every sump here goes in through the bottom of the tank, so the tank needs to be empty and the work kept clean; debris left inside is headed for your filters. Know your tank size and wheelbase, match the sump to your lift pump kit, and verify by VIN. If you would rather not cut into your own tank, we install what we sell.
Frequently asked questions
Do I need a sump on a 2015-2016 6.7L?
Not with the factory fuel system, which feeds the frame-mounted conditioning module and its electric lift pump. A sump comes into play when you add an aftermarket lift pump that wants its own draw point at the bottom of the tank. Check your lift pump's install instructions to see what it calls for.
What is the difference between a one-hole sump and one with a return?
A one-hole sump like the XDP XD182 gives the lift pump a supply pickup. Versions with a return, like the XDP XD243 and the G&R Diesel GRD00153, also route return fuel back into the tank through the same fitting. Pick the style your lift pump kit is plumbed for.
Does running the tank low really matter on this engine?
Yes. The CP4.2 is lubricated by the fuel it pumps, and running low or out of fuel accelerates its wear. Diesel Hub recommends never running the tank low and using a lubricity additive at every fill.
