: TTS Lift Pump Question
theunderlord 07-15-2009, 02:59 PM Been researching/searching a ton and I have a question that I can't find the answer to here.
On the TTS pumps, there are two that they sell, single and dual. What's interesting is that the single says "good to 375 RWHP", can't you make more than that with the stock system and a good programmer/tuner/etc ?
TTS seems to be clearly the best deal out there for the price vs. what you're getting.... Just trying to learn more about them.
thoughts/comments ?

theunderlord 07-15-2009, 05:52 PM It's hard 'cause you can't search "TTS" so I've been sifting through pages of "pump" and "lift" keyword searches... :D
KEVINL 07-15-2009, 07:03 PM I would go with the duals if you plan on running 500+whp

I agree, just wondering why anyone would go single?
paint94979 07-15-2009, 07:14 PM go with the original type of those pumps "Kennedy Lift Pump" TTS is a mere copy of John Kennedy's design
paint94979 07-15-2009, 07:15 PM I agree, just wondering why anyone would go single?
Because my PPE Lift pump flows more GPH than the AirDog, FASS, and TTS pumps... 160 gph compared to 150 and for the price i can buy 2 PPE pumps for the price of one Dual pump.
bcjoe 07-15-2009, 08:33 PM Have a look at the new airdogII 165 gph got mine from alligator and couldn't be happier.
KEVINL 07-15-2009, 09:05 PM The Dual pumps are quiter than the big singles
scramHD 07-15-2009, 09:31 PM TTS dual lift pumps good for 600+ rwhp (with pickup)
also the dual pump setup are flow through design meaning if one/both pumps quit, your truck wont.
S Phinney 07-15-2009, 09:58 PM The dual pumps are good for well over 600 hp. The only two draw backs are if you live in a cold weather climate with road salts you will have some pump failures. The other is the control module does fail regardless of what Steve may say about those failures. The positive about that is they can run just fine without the control module. They are so quiet that you won't hear them run. I do like mine. There may be better pumps for certain situations but my main concern was noise when I purchased them.
duramaxdiesel 07-15-2009, 11:48 PM I'm telling you, go with the Kennedy pumps. You won't regret it.

They are the same thing. John's and Coles' are the same pump. There are some complaints about Steve's having corresion problems in areas where they use salt in the winter, maybe John's are sealed better. I have TTS and I live where they use chemical in the winter, had mine for over 2.5 years and 50K miles and no problems. I did install a gauge due to the fact you can not hear them. I have a PPE on another truck, it is very noisy.

... LOL there is nothing quiet about out trucks. I like hearing my pump that way I know it is on

How loud is it?
theunderlord 07-16-2009, 11:59 AM Nice discussion!
Kennedy (http://www.kennedydiesel.com/detail.cfm?ID=399) 200 bucks each pump
TSS (http://www.ttspowersystems.com/GM_Diesel_Fuel.html) 485 bucks for two.
Not a lot of road salt up here in the Northwest, looking for easy installation and longevity, sounds like either would work great.
bluebyou2500HD 07-16-2009, 05:11 PM my tts pumps are running good had them for over a year in the NORTHEAST lots of SALT on roads but they are super quite u have to get under the truck and feel them vibrate to know there working..... curious duramaxdiesel how did u install a guage to see if they work????

I don't know aboout duramaxdiesel, but I installed a fuel pressure gauge down stream in the fuel supply line, can see it the pressure and see the second pump kick in when you reach enough boost. I love them, My old FASS system was so loud I thought I had a washing machine under the truck. For race applications you can't beat MITUSA. They are the best and being belt driven and under the hood, no break downs and no salt.;)

tts comes with wiring, kennedy does not. kennedy also sells wiring harness, but its extra 145
bluebyou2500HD 07-17-2009, 09:53 AM subman631 sorry thats who i meant thats a good idea thanks i think im gonna have to hook that up and yah belt drivin under the hood is better and alot more fuel and $$ lol
Kennedy 07-17-2009, 12:49 PM If you were to set the two side by side you would see the difference in quality of componentry.
It's not just road salt, it's any moisture. It's just plain ridiculous to expect a circuit board vented to atmosphere to live in an automotive environment. The Kennedy pumps are, were, and always have been fully potted in epoxy. The TTS units were used as delivered by the mfr which is a recipe for failure plain and simple.
DURAtotheMAX 07-17-2009, 01:05 PM I really dont see the need for a fancy circuit board...just hook the pumps up to any switched/IGN hot 12v power source

Not sure that's such a hot idea... I don't want my pump to still run if a fuel line gets ruptured in an accident and the key is still switched on. :rolleyes:

volumejunkie 07-17-2009, 04:57 PM I like kennedy's harness. Pumps dont run (except for a couple of seconds when you turn the key on) without oil pressure. However there is a box to mount under the hood with a button for priming the fuel system. The harness is worth the extra money imho.
Mike L. 07-17-2009, 05:07 PM :DI replaced my TTS pumps with the Kennedy pumps.

Yeah, because diesel is such an explosion hazard like gas is. :rolleyes:

The pumps have ckt boards inside the stator housings. The housings as delivered vent to atmopsphere. Mine are filled with potting so they do not breathe. Try mounting your EFI Live controller in the same place as your lift pump once and see how long it lives...
scramHD 07-17-2009, 07:54 PM Dual lift pump shootout.....
I see two sides here. One potted and one not. :) Does this have any cooling/heating effect?
What is the flow rate of these pumps?

John I was referring to your wiring harness...not the pumps themselves...sorry I should have been more clear. :)

I see your point, but diesel can still can catch fire. We agree to disagree I guess. I paid extra for safety and piece of mind.

How many jets crash and don't burn?
Only those that are out of fuel.
Diesel, Jet A, no difference.

That was kinda what I was getting at. I also never mentioned anything about an explosion either. It's all good, to each their own. :ro)

Im guessing you arent a pilot. Thats because the fuel gets vaporized upon impact. When you crash a jet, the fuel tanks suddenly build intense pressure and heat from the impact...then the tanks blow open and vaporize the fuel...under these conditions YES kerosene will burn easilly with the spectacular results that we see on TV.
In a car accident, not so much. Go pour some diesel on the ground and throw a match on it if you dont believe me.
