I made 588hp with a single KD pump.. :dontknow:
Click to expand...

I'm not saying ur pump can't support 450 I'm saying ur pump will drop supply

run ur kd I could care less the pump is great at 450 less but it aint worth a hill of beans at anything higher IMO


If u care to prove me wrong show me a log of it supplying atleast 10 psi at 450 plus:hug: it won't Brandon!


Wicked diesel aka shane posted we need more psi and I have the same from Bosch

if u choose to push the limit , good on u!! But that's not how I roll

Whoa buddy....


I was just saying that you don't need to break the bank on a fuel system to break 500hp.

I have no idea what the inlet pressure was, don't have a gauge. I do know that it held 22k+ with a 3200 shot tho.


My days of "playing" with this truck are done, can't afford to fix it if it grenades... It's just my DD and occasionally hauls some shit to the dump.:thumb:

You would need to run 6 kd pumps to keep up with 1 fuel lab pump
I have kd pumps in my 05 and they are good for about 450 hp anything after that they start to drop supply pressure to the cp3 and that's not good for racing or sled pulling or the cp3

You do know there are different sizes of Fuel lab pumps right? And there low pressure one has about the same flow as KDs pumps. Not much point in getting the biggest and baddest when your a weekend warrior. Its not like our CP3s are dropping like flys anyways. Didn't you run the Mitusa pump how did it compare to the fuel lab? I'm guessing you running the big dog 42402 or are you running 2 of them?

I run the 42402 as a single at 12 psi and accoding to the graph that is close to 240 GPH

Ive also never ran a Mitusa.

So what is the gph on KD pump?

i wired and plumbed the pump up this weekend, and my filter drain plug popped out with the pump wired on the low setting, running only for a few seconds. The pump is not regulated, and i was under the impression that it would run at 10 psi on the low setting, i have to buy a regulator and a guage :eek:

ya or it will burn up the pump you probably had 120 psi going to the stock filter:( lucky that is all you did

You can run any type of regulator and gauges are like 10 bucks if you get the regulator from fuel lab it screws right in to the pump

you wil need to T into the return line for the return fuel off the regulator or somehow get back to the tank

FWIW fuel lab uses ORB fittings NOT npt or jic

What if i regulate it with a regulator under the hood, and have the return line go through the FICM, and back into the tank? the pump i got is for 1800hp carbureted hp, 20 psi max and 200gph.

that should work:) IIRC stock is 10mm line close to a 3/8 as long as it doesnt restrict your cp3 and injector return rates. I dont think it would but you will know once you first fire the truck

i would almost like to do a custom set up and use the supply as a return then and use 3/4 line to the pump in/out with a seperate filter

So I may as well ask. Is there really a difference in fuel quality with an AirDog/Fass with filters and any other lift pump with a filter setup. Assuming both pumps run the same pressure and both filter the fuel to the same micron. Is the AirDog/Fass worth anymore money? Is the air removal all hype? Any hp/time difference? Do those pumps really do what they say?

Granted its just my own opinion but ive never seen issues. Ive been tought thru work all about 90s vs sweeps and how air can enter the fuel systym the engineer side say you need to consider it but the practical side of me has yet to see any difference.

I made both mine and trents fuel systym and when i made trents i tried to make it the more engineered way....mine was more throw together and i dont think there is any difference but thats JMHO

Trent and I both have big tunes that command alot of rail press and i see minor drops to where he maintains rail But he also has bigger cp3

I think the fass 250gph would probably do the same but what i really like about fuel lab is that they allow 12 an into the pump and im not sure about FASS but if you ever look at fluid dynamics you would never flow 250gph from a 1/2 inlet without a precharge pump......exactly why fuel lab uses a 5/8 inlet

Now people will argue that they have done this and that and i have no reason other than i like this pump to say this stuff.....but there shit makes sense to me, Run a Fass or air dog as they are good pumps im just simply commenting on something different:)
