6.7 fuel pump on a 6.0

Not real familiar with the 6.7 but I see the fuel pumps look similar and the 6.7 has a much nicer water separator. I also have heard that the 6.7 runs higher pressures then the 6.0 75+ psi. Any one have any insite?

Higher fuel pressures aren't always a good thing. A lot of guys are running true regulated returns that are adjustable and most have them set somewhere in the low to mid 50's range. The 6.0 HFCM is capable of 100psi, it's demise is lack of volume.

Interesting idea. Here is a copy/paste from another forum. Just need to find the volume of fuel that the 6.7 can supply.




The low pressure fuel pump is located
inside the DFCM assembly.
The low pressure fuel pump draws
fuel from the fuel tank through the 10
micron primary fuel filter and pushes
it to the engine mounted fuel filter.
The fuel pump pressure relief valve
is integral to the fuel pump and is not
serviceable separately. The fuel pump
pressure regulator limits fuel pressure
to 827 kPa (120 psi).
The low pressure fuel pump
supplies approximately 3 times the
maximum amount of fuel required for
combustion. The excess fuel is used
for lubrication and cooling of the high
pressure fuel pump.
The IDS has a PID FPL_CMD# to
command the low pressure fuel pump
on and off.

the 6.7s are common rails, 6.0s arent. i dont see how the 6.7 pump would work on a non common rail truck.

and yeah, its volume you want....pressure too, but more volume at 50 psi, is better than less volume at 75 psi. less volume will cause pressure drop. which you DONT want.

It's the low psi fuel pump we are talking about. The 6.4 is also common rail, but you can still use the low psi pump to feed a high psi pump like a AD2 or 6.0 HFCM.

this is what im working on as we speak. min pressure of this pump is 55 psi max is 120psi so it has 1/2 inch line in and out and is high volume to boot! this my be my next set up i just wish i had regulated return so i could just plop one in!

With the 6.7 having 1/2" lines, theoretically it should also have the volume needed.

If you need a reg return, I could pimp you out at the local gentleman's club!! LOL!!

My thoughts exactly from what I was reading the 6.4 only runs about 5-10 psi but I'm guessing a lot of flow to the high pressure injection pump. Just thinking that the 6.7 pump would be more cost effective if you could make it work let me know how it works for you! I'm glad someone else was thinking about this. Would you need to use a larger pickup in the tank as well?

I would just for insurance.

if the gph is high enough, problem solved. Haven't heard too many failures on these pumps either.
