I have kennedy's pumps and they arnt boost refrenced. I hold 11 PSI at idle and about 5-6 PSI wide open.

I have kennedy's pumps and they arnt boost refrenced. I hold 11 PSI at idle and about 5-6 PSI wide open.
so one pump dosent run at 3 psi and the other as boost and rpm rises the second pump comes on
Mine arent boost referenced either,Because I didnt purchase his harness
no way mine ever seen 11 psi though
8-9 PSI max but they are old models but still wotk greatIf I was going to choose between a WD and air dog I would go WD btjmo
so one pump dosent run at 3 psi and the other as boost and rpm rises the second pump comes on
i bought everything from kennedy so the pumps only run when the truck is running. I have my gauge coming from the fuel port on the motor. Kennedys kit also came with the 5/8's pickup. I see 10-11 PSI at idle on my isspro gauge....I think if you buy the pumps from TTS i think their harness is boost refrence.
oh hmm i thought they where the same just tts was the ripp off version of kenedys. good to know
I think kennedy buys the pumps from TTS then he fabs up the rest of the kit. You can get the twin pumps from TTS with boost refrence harness but i dont think they offer a secondary filter like kennedy does in his.
Kennedy does not buy pumps from TTS LOL Cole copied Kennedy's setup... long running story.
Oh sorry i blew up
I did not know that. Sorry about that. Anyways the pumps are great just a bitch to prime. It took me a long time to figure out if i would of read the directions it would of took me 5 min to prime them instead of 3 hours....:rofl:
only complaint I have about KD pumps is when running that they draw down quite a bit when running duel cp3,But it is possible that my seconday frame filter is restricting some of the fuel?
They are super quiet and have lasted a long time 100 000 miles +
Dale got the newer style when he ordered his and they are suppose to be a lil higher pressure
But as far as higher perfomance I would like a pump that wont draw down JMO

I never even got instructions?
What do you mean hard to prime?the cp3 draws fuel and as long as you dont have any leaks you shouldnt need to worry about priming the pumps
Placement of the pumps sometimes causes air and makes it difficult to get rid of.....reg. cab is hard to find a place to mount them with the filter.
The black ones are a little stronger than the blue ones.
It will be hard to find a pump that you set up to deliver the fuel you need and then ask it for the fuel you want.....unless you put a big ass pump on it. I like the Air Dog FWIW.....all in one, quiet, and flows enough to make plenty of power, ut I don't like the idea of recirculating all that fuel. I know it won't hurt anything, but I don't want it....the Kennedy set up is basically a lift pump for the every day hp producer that will never be a conflict or leave you stranded. It is not a strong pump or a puller by any means, but I also would like to maintain more positive pressure under demand which is why my set up is not in stone yet.....but you can bet it won't be one of those noisy ass BG pumps.

This is something I never thought of before. All that recirculating of the fuel is likely to just add unwanted heat to your fuel system unless you have a good cooler with a fan on it. Especially if you run a small fuel cell.
I know on Simon's race truck, the cooler was upgraded but we never added a fan-something I think we should look into seeing as we are going to run two fuel circuits.
Thanks for the input BD!! It got some more wheels turning here

We ran the wire for the fan just never installed it.....But I believe I have the cure for the hot fuel
I downloaded the instructions off kennedy's website . In order to bleed the pumps correctly you have to crack the bleeder on the pumps and force air into the fuel filler neck until fuel comes out of the bleeder screw. The kennedy pumps will not prime themselves. I have the black ones and they do pull down. I guess you could always add one more kennedy pump and make the boost refrenced some how. I dont know how that will work but it sounds good :rofl: I have my pumps mounted on the outside of the framerail on the driveside right under the fuel filler neck. It was the only place it would fit...

Ya we'll see.........
I have never needed to prime my KD. But I am only running a single not the twins.
i apparently have the newer black ones. Kennedy's harness runs off of oil pressure. They do prime when they get a 12v switched signal but wont run till you have oil pressure. I started out with a fass 95gph, but it left me stranded on the freeway one day.
From what i have seen some FASS pumps are loud and some are not. My 150/150 is quiet for some reason. I have a friend whos FASS is ungodly loud. I have seen a quiet PPE pump and really loud ones too. Over all i love my FASS because of the filtering system.

I have a FASS 150 with filters on my truck too.
The original pump was kind of quiet, it's mounted inside the dually fender near the rear wheel, with the engine running I really didn't hear it.
Fass had some kind of upgrade recall to their motor's because of brush problems on some, so I traded my motor in for a new improved one, and it was WAY to loud, maybe 3 or 4 times as loud as my original.
I wasn't living with that noise so I had them send me another motor and after I swapped that one in it went back to being quiet again like the first one was.
Don't know what was different between the motor's but there noise difference was big, if you have what you consider an excessively loud pump you might try and give them a call or talk to the dealer and see if you can get it swapped out.

I really like the idea of the Wicked Diesel lift pump system, especially for guys that are restricted to a single CP3 for their pulling class. I have been told that with the DIY CP3 mods on an LBZ CP3 in an LLY with stock sticks they were holding 25,000 PSI rail pressure at 3000-3200 PW and making 580hp on a modded stock charger (64mm compressor). This wasn't with the WD kit but with a home brew kit that did the same thing. I think together with a stroker CP3 you would be getting close to what 2 stock CP3s will push, but I have not tested this.
