Not real sure about TTS's pumps (I think they are similar to Kennedy's though), but Kennedy's have an estimated 40,000 hr service life. Thats a LONG time, thus its a do it and forget it type thing. My understanding is that both kits are complete with everything you need to put them on. That $800 price on the Kennedy's includes more than the TTS kit too IIRC. The $800 price includes the billet fuel pickup if I'm not mistaking and might even be the kit with the aux. mega fuel filter as well. I don't think either of those things are included with the TTS kits for $500.

Good luck deciding which one you want. I'm in the same boat as you but TTS isn't one of my options (not a value thing, just a personal preference or lack of, in TTS products - as far as I know they are good though).

I have my pumps broken down into individuals, complete kits, and complete kits with filter assemblies. The price you mentioned was pump/filter combo. My complete kits cover pickup, mounting, etc. I have built custom heads for mine from billet aluminum and anodized them with all stainless hardware. They join together with through bolts and seal with a single oring rather than pipe threads. I could have used the mfr's bronze heads, but wanted something better, neater, cleaner. Once you hold them in your hands you will see why they cost a little more...

The kennedy kit is a complete kit and has a filter head that can be added.........I have the twin pumps with a 2micron filter and replaced a fass with it . I could not be happier. It is so quiet you can barely hear it run..........the harness is complete with oil pressure switch to shut off the pump if a accident should occur. These pumps were selected by john for this application and were touted as fish aquarium pumps by our resident diesel guru from tts but who has since choked on his on words-:t and now sells them in his kit.............Get the orginal design........you wont be disapointed

The TTS Kit and the Kennedy kit both use pumps from the same manufacture, they were orginally design to pump hot water and are listed as such on the manufactures web site. John nor I designed the pumps we all just buy them from the manfacture just as anyone else can. At one point John said he did not use the pumps we did but I think that is not truely the case. What both of us have done is to make them a part of a kit that installs them into a duramax truck. Our's are full rubber mounted and come complete with electronic controls and all the factory connections for the fuel lines so there is no need to push rubber hoses over fitting they were not designed for.

As you recall I posted the pump manufactures web site and John said they were not the pumps he used, I said they increased power output and post dyno graphs to go along with it, John said they were not needed and did not increase power output now he does. I also said 2 pumps were needed for bigger power output John said only 1 was necessary as they would not increase power. I design the original billet pickup and John said it wasn't needed and now he has copied it and said it's needed. So what do you want me to fess up? :D

So you are telling me I will gain hp simply by bolting on a lift pump?
Please post a link to the graphs.
Thanks

I'm sorry, but I just can't do that. It would undermine my working relationship with my dealers. These pumps as well as my KD big bore billet are available through:

Guy at SoCal

MikeL at Inglewood

Eric at Merchant

among others...

You will pick up HP if your running big tunning. On a stock truck you wont see crap IMHO.

The pumps from kennedy and TTS are the same pumps......just differences in electronics, mounting, and price.

Or you can peice together your own kit with other pumps. Many other choices......

In answer to your question though.......If you have to prime your truck to start it you dont need lift pumps. Lift pumps will just be a bandaid to a problem you have. IMO investigate the actual problem and fix it.

Glad to be of service Dave.

Lift pumps will not gain any Hp if you are adding them to a stock truck and a fuel pickup will not add any Hp on a stock truck. The only reason you would add lift pumps would be for a increased power when using a higher Hp program. They will not hurt anything and may also add some life to the CP3 and injectors by keeping them full of fuel but that has not yet been proven. What I can say and have always said is adding a lift pump came right out of the Bosch fuel system design book. They show the common rail design with a lift pump as part of the basic design GM just felt it was unnecessary and saved a few bucks by not having one.
