Alright I'm sorry mdub but some bigger performance injectors. And yes I was looking at the ad2, and thanks karls

 

Karl, the fact that not only you have had so many problems but so have a lot of other people had with the AD2 is the reason i said go with the A1000 fuel pump or a fuel lab. But i have been doing a bit of reaserch on both pumps and they are both only rated to 45psi which is IMO not enough fuel pressure to keep our injectors cool and running smooth. Although i see a lot of people running them so i must be missing something.

To OP, if i was you i would run something like my setup but also have a regulated return. My setup is fuel tank, AD100, stock water separator/ frame rail mounted fuel pump to fuel filter on top of engine. I also have the "blue spring" upgrade in my FP regulator. With this setup i should see 65+psi under load but since i need a new stock fuel pump ($175) im only seeing best of 62psi under light load and 52psi under heavy load.

 

Josh. So your system is stock except for the pump in e tank and the blue spring mod and a regulated return system? I was wanting to run an ad2 because I can get better filters for it then I can a stock system to filter the fuel better and help save the injectors life. And to do away with the top fuel filter since I wouldn't need it with an ad2 correct???

 

My setup is Tank (has no pump stock) to AD100, to stock fuel pump/water separator to top side fuel filter and blue spring upgrade. IMO i dont see a point in getting rid of the stock topside filter or rail mount fuel pump myself unless you are running 190 or bigger injectors with 100% nozzles. But im no expert. IMO a better setup for you would be something like mine or a aarmotive A1000 with some type of water separator and fuel filter setup. Reason being that i have seen a LOT of problems with the newer AD2 with a lot of pump failures. The only reason i am running the setup i am is because i dont want to get rid of the filter on top of the motor and already had the AD100 at the house from another build a while back that i ended up not using it on.

 

The beauty of the AD2 was it had a built in adjustable regulator, which mean it eliminated the HFCM (stock fuel pump), and you can run right to the heads bypassing the upper fuel filter housing (and regulator, ie the blue spring). However, with all the issues everyone seems to have...

The ideal setup IMO (this is constantly evolving, but I think I'm at the point in my understanding of fuel systems and the point in which I've read every fuel system thread on the internet...) is a sump (or whatever means of draining fuel from the bottom of the tank, KARL... bulkhead fitting...whatever haha), feeding into an AD 150 or something similar (lift pump) feeding into an A1000 or Fuelab pump (41401 is the common one used). From there, feed directly to the heads (eliminate the upper fuel bowl) and a regulated return system. The only time pressure will drop is when you turn the key off.

 

Of course your wallet will be empty from $2000 in fuel system parts...

 

I don't have an AD2, jimrd does.

I'm just passing on info that I have found related to it.

I can see how the AD150 comes into play removing the air from the system, but why do you need the A1000/Fuelab pump? Wouldn't the frame mounted pump suffice? Isn't the AD150 a stand alone fuel system that can also move the fuel to the heads, or is it just for air removal?

Check the demo video here, it's pretty cool.

I don't think the AD150 is really good as a stand alone unit and is running pretty hard to maintain 55+psi. It works best as a lift pump supplying 15psi to a bigger pump. The fuelab and A1000 are meant for the heavy need for the 6.0. You can certainly run the AD150 to the stock pump too, a lot of guys do that and can support decent sized injectors that way. If the stock HFCM fails, it's a good time to just eliminate it and go with a fuelab or something though. So to answer, yes the AD150 COULD be used by itself, but the failure rate seems to be high (AD2 anyone? Hmmm....). Also with the fuelab and AD150, you've got filtration, air removal, and two pumps which means if one fails you can still get home.

Some also go right from the tank to the fuelab or A1000, which can be done, but make sure you've got your hoses and supply set up correctly. You'll also need to add your own filtration. A1000 manual says that the ideal setup is having the fuel gravity fed to the pump so it doesn't have to work as hard to suck it from the tank. Even with a sump, I believe where the pump mounts on the frame, the sump sits lower than the pump, so it's still having to pull uphill so to speak.

 

Don't forget our injectors are a lot more money and way more picky than yours. We need to maintain good fuel supply to them to prevent damage.

I think you could still do it way cheaper...

Stage 1 RR is $400 right now (usually $450 or so)
A1000's are $300 right now (not sure what they usually go for, or how much the fuelabs are)
Sump is $150 or so, but you could do something cheaper
AD150 -... ? $550 or so!?

Still expensive no matter how you slice it, that's for sure. Don't forget a fuel pressure gauge too, I think I paid $135 for mine.

 

Mdub- (slight thread derail kinda). I know you have been trying to convince me of getting rid of the stock rail mounted fuel pump since i already have the AD100 and a sump. I have been doing a lot of research and have a few questions about if i go this route. If i do get the A1000 and delete the stock pump and top side filter would i need a regulated return and the A1000?

To the OP- (back on track) I have been doing a lot of research on this and it seems that doing the AD100 to the A1000 is a good setup but i am still trying to figure out how to set it up and make sure i have good fuel pressure (60=psi @WOT). The reason I would go this route is that I have seen to many problems with the AD2 having motor issues. Not just on fords but all diesels. The older ones were good but the newish (last few years) have seem to have more pump problems.
