I have a 2003 5.9 HO Cummins that has been converted by the Dodge dealer to the in tank lift pump. Recently replaced the OEM pump with an Airtex in tank lift pump at 173K. Of course had to drop the tank.... I should have a video posted with my install of the airtex here in a couple of months (have a lot of videos to edit). Anyways, if my truck still had the lift pump connected to the fuel filter canister I would have definitely replaced it with a FASS, they make a specific "direct replacement" kit for the 03-04 Cummins.
I have an 03 with 171k. Pay attention to the fuel. It's nearly the same consistency as gas. They have removed a lot of lubricity from diesel. Knock on wood I haven't had to replace anything in the fuel system yet. Every other tank fill-up I add half a gallon of atf. Just to add more lubricity to the fuel and protect the fuel system components. Unfortunately on my 05 I have to go through the fuel system with new parts. That in tank lift pump will go bye bye. That's an idea that should've never happened. I'll go with an external lift pump. It's much easier to replace if it does fail.
When my pump failed I was driving up a steep hill. It bogged down and shut off. It started up again but shut back down after a couple seconds then wouldn’t start again. I got a code for lift pump circuit low or something like that which made me realize it’s the pump. When turning the key on I didn’t hear the pump run anymore.
Good job, informative and concise. I'll try to be the same and like you hope my story helps someone else to find a way to better reliability. What I'd really like to know is why, in 186,000 miles I have had three lift pump failures. After being stranded on the side of the road with a trailer and $391 to the towing company to bring me, my wife and my truck home from 60 miles away I am looking for the best most reliable solution I can find to this lift pump problem. It is a bunch of crap. The tow truck driver said the three most common Dodge Cummins failures are Lift Pump, Water Pump and Ball Joints. I have an '04 ISB305 made in September of '03 and installed in the truck in October of that same year at the factory. I had a factory fuel filter mounted lift pump. I have been left on the side of the road now THREE times Failure 1, 111,000 miles 111,000 miles to failure, 12-27-09, $956.00, Dodge Dealer replaced original on fuel filter pump with Dodge in tank pump. I really wish they had not done me that favor. Supposedly Dodge did not offer the original external pump on the fuel filter. Failure 2, 152,000 miles, 41,000 miles to failure, 5-15-16, over $1,000, Dodge Dealer replaced retrofit intank pump with another one just like it. The intank pump is more reliable? Really? It lasted less than half as long as the original fuel filter mounted external pump. Failure 3, 186,000 miles, 34,000 miles to failure, 6-26-21, $391 for towing 60 miles to home, my trailer is still stranded in a stranger's yard with the load still on it., pump not yet replaced but you can bet your ass it won't be with the Dodge intank crap. I'm going to suck all the fuel out of the tank and polish it with a little filter unit I build with two Racor filters on it. I have NEVER found any water in the filter on the truck. The first failure I was litterally chasing a needed ambulance that flew past our address, the second time was pulling a stock trailer 50 miles away from home and the third time was pulling a 16' pipe top 60 miles from home. I'm damn tired of this. Looking for a better solution.
I have a 2003 Dodge Ram 2500 Cummins with 262,xxx Miles. While I’m driving it feels like it’s losing fuel/fuel pressure. My question is, year ago I opted to a air dog fuel system since it was cheaper then a oem and seemed from the info. More efficient. Since I have an aftermarket(Airdog fuel pump) could this be causing my issue? Or since I have the Airdog is that part you replaced in this video bypassed? Thanks
I have a 04 my vin number comes back showing a high output Cummins ?? I have 150k I replaced the fuel injectors with ones from a local dodge dealer installed them now it will not start I took the top cap off from fuel filter bowl bumped the starter not much fuel flow replaced lift pump same thing I ran a inlet line into a can of fuel it sucked it dry fast hook it back up same thing again trickle of pressure into bowl I blew low pressure of air into tank no obstruction from tank idk
I guess I’m doing pretty good then. Mine doesn’t have the clamp. It’s an 03 HO. I guess that means I still have the original. 364,000 miles now. Replacing it today as soon as the parts store gets it in.
Yeah I limped it to an autozone that got the lift pump in somewhere in the middle of Missouri and changed it in the parking lot. Been running great since.
Great video man. Have you had any problems with your rpm’s surging at times while driving down the interstate or highway? I’m thinking that the lift pump could be my problem but not sure. Thanks!
Where is a good place to order a replacement one for inside the tank from the original lift pump thats on it and do you have a video of doing that job. Thanks 👍
@@OutpostCTD Oh boy haha. Maybe I’m hearing something else. I picked up a stock replacement tonight so hopefully I’ll be able to report back with good news tomorrow. Thank you for the reply. Your channel has been an absolute wealth of knowledge man
@@OutpostCTD Got a new factory style pump put on and now I can HEAR it haha. Not sure what I was hearing before but this is very clearly running and pulling fuel. Back on the road I go👍🏻
I have seen that Carter was the original company that made the pumps for Chrysler/Cummins. I saw the box in your video said Carter and i'm wondering what site do you buy them from?

So you are saying, turn off the OEM lift pump and install the FASS pump in the rear wheel well, correct?

Mine failed with 142k on the clock.
Left me stranded this evening.
03 3500.
Great video man!! what brand are your fender flares ? Love them
Thanks
Did your truck stall before dying out? And after did the lift pump not prime anymore?
When my pump failed I was driving up a steep hill. It bogged down and shut off. It started up again but shut back down after a couple seconds then wouldn’t start again. I got a code for lift pump circuit low or something like that which made me realize it’s the pump. When turning the key on I didn’t hear the pump run anymore.

FASS lift pumps

Six months after I got my truck they replaced it at the dealer with a drop in. That was in ‘06. Got about 380k miles ago.
I guess I’m doing pretty good then. Mine doesn’t have the clamp. It’s an 03 HO. I guess that means I still have the original. 364,000 miles now. Replacing it today as soon as the parts store gets it in.
Nice!

Believe or not…. Mine is doing the same….167K….. 2004
A question friend and the pump that goes inside the fuel tank, what should be done?
Thank you for your teaching us
Where is a good place to order a replacement one for inside the tank from the original lift pump thats on it and do you have a video of doing that job. Thanks 👍
Check out Rock Auto or Geno's Garage.
Did u do a video of replacing the pump?
I tried to film some clips but it was tough to see what I was doing.
@@OutpostCTD ok, thanks. How long would u go with the factory pump before replacing?
@@The_MM_Life I think 150k is a good point to do a preventative replacement and keep the old one as a spare.
@@OutpostCTD ok thanks for the help. Really enjoy ur channel
did you make your own gooseneck hitch? A video on that would be awesome looking to make one possibly as well...
When they fail and won’t fill the fuel bowl can you still hear them running?
When mine failed it no longer made any sound.

P.O.S . Just bought one. Duramax only
