Help needed in determining best lift pump for my towing needs.

I am the proud owner of a 2004.5 LLY since 2008, stock 93K miles 2wd crew cab short bed.

I have not used her much, but now need to put her to work towing a 10K travel trailer from east to west coast and back annually for the next few years hauling stuff to trade shows.

I have recently invested in a Banks EconoMind Tuner with the iDash SuperGauage, plus the Banks SpeedBrake.
I also purchased the 4" Monster Exhaust System Single Exit.

I am looking to gain power, help slow me down coming down mountains, and not have a loud exhaust, or waste fuel. I have an S&B wide Mouth turbo inlet I installed, along with an egr block off plate, and also a cold Ram air intake with K&N oiled filter. many years ago.

I am now trying to determine what would be the best lift pump kit to complete the modification upgrades.

I have looked at the FASS TS C10 100G, Titanium Signature Series Kit, which is 100 GPH. They currently have the kit with 2 filters that mount underneath to the frame with a scratch and dent scenario with $150.00 savings proceed at $585.00 Also, The FASS Dura-Max Flow enhancer Dmax 7001 which is $426.55, as well as the PPE Electric Fuel Lift Pump GM Duramax 113050000 which is $180.00 plus a few hoses I believe.

Can anyone by chance be able to recommend what the best choice would be for my needs without spending anymore money than need be and have confidence the CP3 pump will be fed all the fuel it needs and not be starved like it can with factory fuel system on these older Duramax's?

I have never broken down with her and want to keep it that way if possible.

Thank you kindly for any tips in advance!

All you need is 30GPH and something less than 10 lbs pressure, preferably 5 bs. No one needs 100 GPH unless they're doing all-out racing. My pump has been flawless since 2010 and I pull a 30 ft 5th wheel with no problems whatsoever.

Thank you Ron, I will take your advice, I am new to this tech, can you recommend a good pump kit that fits the bill? Are the external filters necessary a good idea?

Thanks again

Everybody has different opinions on lift pumps, mine is whatever you choose I would add the filter system with it as while traveling you never know what the fuel you purchase is like. That being said I like the Air Dog system l have, I’ve replaced the motor 1 time in 10 years and it was replaced under warranty and I ran the truck 500 miles or so before I even knew it wasn’t running. It is a flow through design so if your fuel system is tight the truck will pull fuel though it without any problem and also you won’t have to change the stock filter nearly as often, I change mine once a year if it needs it or not.

Thank you kindly for your input, can you recommend a model from Air
Dog, and what GPH and having 10 lb Pressure or less, I only want efficiency / power and fuel economy in the best bang for the buck so to speak.

The basics of a 'lift pump' is pretty simple: plumbing from and to the existing fuel supply line, a filter head and fittings, a filter, pump, maybe some shutoff valves, wiring, and electrical supply 12V. The attachment shows the basics of the lift pump and some of the many variations possible.

What is missing from the document is the pump itself and the electrical system to run the pump. I used an Airtex E8153 pump (about $50 now) plumbed into the truck's metal fuel supply line after the filter (pumps like clean fuel to pump), and the electrical supply came from a pin in the the MBEC (electrical supply box near the brake pedal) that is already fused to 15 amps and supplies power anytime the key is at start or on. There are other pins in the MBEC that have other options. I ran the ground back to the battery on the driver's side. I only installed 1 shutoff valve but will install another one next time I change that fuel filter.

Remember, a supply of fresh well filtered diesel fuel is the best thing you can do for a diesel engine.

Thank you Ron for the document, very helpful, and I am fully motivated to build my own as you describe and save the money.

I have a diesel fuel pump new in box I purchased for diesel fuel purging and never used, here is a picture, do you think I could use this as my pump? it is meant to be the same flow as a Ford I think, I can't find spec online and no documentation in the box so I have reached out for tech specs from the manufacturer, but I am think it could work perhaps...it is an aluminum housing. Osias Model # 501700.

I will gather up the parts, I like the way you mounted the plate to the frame, well done!

I see some of these premade kits have 2 filters one is fuel, and second being a water separator, should I just buy 2 filter bases so I can have the option for both?

The filter bases and the pump are the harder to find items I will search online for, the plumbing fittings and electrical items are easily found at Lowes etc I would imagine.


Thanks again,


Tibor

As stated earlier, there’s lots of opinions on lift pumps. And I’m sure nobody cares to hear mine, but here it is, lift pumps are unnecessary For most applications. Even the secondary fuel filters. I’ve had numerous Duramax trucks and I’ve never added a lift pump or secondary filters and yet I’ve never had any fuel related issue. And I have filled up at some pretty scuzzy gas stations around the country.

A good filter in the stock location has worked fine. And from my experience of working on other peoples trucks, the aftermarket lift pumps and filters, and everything are a huge hassle, they leak, and are just a pain in the butt. I literally have a truck here right now that just leaked about 15 gallons of diesel on my concrete because the aftermarket pump/filter assembly decided to whizz fuel out overnight. Spent the weekend trying to get it cleaned up.

Definitely something I would never think about adding to my truck. But also, as mentioned earlier, if you have a high horsepower race truck, then yes, you will need a lift pump, but in your situation I personally don’t feel that you do. There’s days where I’ll run over 100 gallons of fuel through my truck, filling up at unknown stations, and the stock filter has always done great.

and since my opinion is contrary to everybody else’s, I will now get reamed out and flamed.

Your points made are very good and I appreciate it Hoser , it is difficult to separate fact from fiction a lot when it comes to this tech, and yes no high horsepower here... so it makes sense what you are saying completely. I just want reliability and this notion that Duramax's don't have a factory lift pump and suck the fuel rather putting strain on the pump and it if fails it starves the injectors and causes 15K in damage is the points that led me to explore this avenue and it if applies to me. I have already spend a ton on the other component, Banks Tuner, Banks Brake and Exhaust upgrade so I am not pumped to spend more if not necessary.

I have 93K original miles currently would you recommend anything fuel related at this point in time with an 18 year old rig?

Thanks again,
