Dual stock fuel pumps...Is it possible?

I am running 190s right now with the stock fuel system. (I have a fuel pressure guage and can only push the skinny pedal half way). I am picking up a parts truck tomorrow for the engine/trans/xfer case and was just wondering if it is possible to add another stock fuel pump inline to gain the volume required of these 190s.

I will eventually make my own regulated return and plan on really building it up with a Fuelab pump. But in the meantime, I like tinkering and I will have this extra pump just sitting here.... has anyone tried this yet on a completely stock fuel system? Would it work? Would it be too much? Any ideas on how to do this.

I do not have a sump yet either. Not planning on an ADII nor FASS (too many failures). Just wondering if this dual pump setup will work until I build my regulated return and slap a Fuelab or Aeromotive pump in there.

I'm sure it would definitely work, I'm just curious about a high pressure pump feeding a high pressure pump. Most folks choose to use a low pressure high volume pump to feed the high pressure pump, but that's not to say it doesn't work. This thread fuel pump setup is about one of the members using a factory 6.4L lift pump (low pressure/high volume) to feed his airdog which has helped with his airdog issues but it could be used as well to feed the factory 6.0 frame pump.

I'm curious to see how this works out for you.

I guess nobody has attempted this type of setup before. I put dual 7.3 superduty pumps on my son's OBS with 200/30 injectors and it maintains pressure just fine. Based on that, it should work.. I will be picking up the donor truck today and yanking out the powerplant and anything else salvagable. I will really be able to look at the framerail and see how this second pump should/could be mounted and plumbed.

If it were me I'd feed your stock 6.0 pump with a stock 6.4 pump.

Sure you can do a dual pump i wouldn't so in in series but parallel . if you do it in series the volume wouldn't change. in parallel you could double volume but would have to run it into a half inch feed line. You would also have to draw from a half inch feed tube.

ok guess what im going to make this setup because i have the pumps to do it! ill let ya now what it does and how it flows!! I WILL START IT TOMARROW

iF YOU WANT ME TO WAIT SO YOU CAN DO IT FIRST I WILL!

You give it a shot first. I think I am going. o make my regulated return first becuase my fuel pressure is running 74psi right now with the blue spring. I need to ditch the stock return and feed, keep stock filtern upgrade feed and return lines.
Let me know what you find out though. Waiting patiently.
