I'm sure it is...as its been done and proven...but why not so a sump, a1000 or the like, and a reg return to the tank? Ya know? All that would be close to the same cost of a lift pump & reg return
190/75's Stock fuel pump?

thorobred diesel sells the fass titanium 95 for 540 shipped, you say you can build a better system for less? a a1000 alone is 330$ right? you still need filters bases and all that stuff right? not arguing just asking because i need to do something with mine
Yea it'd probably be a little more...but not enough to change my preference vs feeding stock with a pusher...
A1000-350.00
Reg return-650
Bases & filters-200
Misc fittings and line-200
Pusher pump-500-600.00
Reg return-650.00
Misc sump and such -250.00
Yea there's a price diff but personally I'd like the single vs pusher feeding the stock

i also like the reliability of the stock pump, i think most will agree that a a1000 or the like isnt designed for daily driven vehicles or 100-200k miles, not sayin it wont hold up obviously guys have good luck with em, nor is a fass or airdog lift pump all that reliable neither, but at least if ur lift pump fails you have the stock pump to get ya where you need to go. plus i think its a little easier to install just a lift pump and even a sump if you want, versus fooling around piecing a whole new system together. thats y i kept the stock pump to begin with. although this is just my opinion and how i feel about the whole thing, beings that my truck is a daily driven work truck it needs to be reliable as possible but still have fun with it at the same time.

I agree w you entirely bud...the a1000 and other 'high performance pumps' are designed for just that...High performance race vehicles...but as you said...the OEM pump is proven reliable. You've got me wanting to try a pusher on one of my trucks to compare to the a1000 now lol

no doubt the a1000 prob does a better job for anything over 550hp, just depends on wut your gonna do with the truck i guess. me personally if i can get away with using the stock parts and add just a lift pump as a helper... im gonna. as long as it provides enough fuel thats all that matters. which as been said it does.
I run 205s so I doubt a pusher would keep up the OEM hfcm.... as you said the a1000 is better suited for 550+ applications.
Maybe someone has tried a pusher pump on 205s

id say 205s might be a lil too much for a stock pump. idk tho jus guessing
I wanna agree but haven't seen any data to prove one way or the other...
I've got 1 truck w 205s on a reg return and it gets lowwww towards the end of the track

Did it for a few years and held 60 psi no problem with 190/75's and 500hp. I know guys have used the stock pump with a low pressure feeding it using 205cc injectors no problem with fuel pressure. I now have a Fuelab in place of the stock pump and still have the low pressure FASS feeding it. That's the whole idea of the low pressure pump....so the high pressure one doesn't hafta work as hard to maintain pressure.

Exactly....regardless of the setup you don't want your high pressure pump to have to pull through the filter.

Okay so whats the best way to run the lines for this system. Kinda getting stressed out as I have to leave for Tennessee thursday. So far I have a Holly fuel pump, Cat filter pre and post. Trying to figure out line size and should I install the Strictly Diesel 5/8's pick up tube I have? Do you guys run a new line all the way to the hard lines on the motor or do you tap back into the stock hard lines on the frame? Should I run 5/8's the whole way or after the fuel filter kick it down to 3/8's?

Also I might just end up running a Airdog II 165 due to time constraints. Can I run the ADII with my regulated return or no, and is 165gpm enough for 190/75's?

I'd run the 5/8 pickup tube. You only need 5/8 line from tank to the pump. Then from the outlet of the pump to the engine can be 1/2. Run the 1/2 line to y-block. Then two 3/8 lines from the y-block to the front of each head.

Weren't regulated returns and Airdog fighting each other and burning out the pumps? I heard you are suppose to turn the airdog down and regulate it up to 65 psi on the motor, any truth to this?

Fwiw I run walbro pumps before the factory pump when a regulated return and oem pump can nit keep up. In the event you want more I have an a1000 system that removes all of the stock system. Never has a problem.

Airdogs wiring harness is what burned the pumps up on the airdogII. The wiring was waay to small...pump would overheat and die. Wiring should be 10ga.

Greg is right. The airdog for the 6.4 is a low pressure pump system that replaces the factory low pressure pump on the 6.4. Reason why there's hardly any failures with them on the 6.4. Totally different than the high pressure 165 for the 6L. Another reason you don't see hardly any failures with the low pressure airdog150 guys use as a lift pump on the 6L.
