Here I do a short comparison of the OEM Carter, Ebay Carter, and DCEC mechanical fuel pumps for Cummins 6bt 12 valve engines. I had hoped that the poor quality "Ebay Carter made in USA" pump i got was the cause of my "air bubbles in fuel return line" condition. But even with the DCEC pump installed i still have little air bubbles.

I agree with what he is saying for the most part. I have taken apart a few of the lift pumps. Aftermarket pumps seem to have different quality but just because it is made in the USA does not mean it is good quality due to extremely high labor and material cost also greed many USA company's make crap. China can make crap also or they can and do make some items that are very good. It all depends on what the importer is willing to pay for. And the sad part is many times the difference in cost is just penny's per unit but our cheap greedy corporations will demand the lowest cost so they get crap
Great comparison video! Thank you for just getting to the point and covering the important points of distinction. I am going to try this dcec pump based on your analysis. The weep hole seems like an obvious thing to incorporate. Without that, you're just going down the road with no idea if that seal has failed, although it might create a noticeable pressure change on the guage. Again, thanks. Going to check out your other videos.
I just purchased a Cummins Chinese pump from South Plains Diesel. it has the weep hole in it. 115.00
The nut on the fuel line going into my filter screen was a quarter turn loose. I tightened it and solved my overnight air bubble issue.
That's cool man. I'm Still rocking the dcec pump and it has been good
Southern Plains Diesel
My local cummins parts house in Austin Tx. On Smith road if it helps you search.
HI I had the same USA Junk Cummings pump. We must have got it from the same guy,he told me to get the china Cummings pump .I did It works great,way better constant 25 to 35 lbs fuel pressure,also very easy now to bleed injectors with the manual push pump my USA pump never did work. truck never ran this good ever. Also added a beans diesel fuel sump no more fuel issues . U can see sump install on my channel.good video.
TheKilog69 cool ill check out your video! Thanks for the comment and im glad im not the only one that thought the usa pump was junk! Lol
Its in my Cumming play list, I have about 20,000 miles on it so far my USA pump lasted less than 10,000.
I had the same exact issue. New "Carter" only put it 13psi. Less than 50k on it. Newina Cummins unit works great.

NoNonsenseKnowHow don't forget the square cut seal on the top inlet of fuel pre-heater. Cummins part #3923194.
William Baker thanks you're right, I forgot to add that seal. Thanks for adding the part number!
Put an e bay 0 - 50 psi fuel regulator in your return line so as to precisely control fuel pressure in the p7100 pump cavity. Set it 2-3 psi below lift pump max.
Check to see if your lift pump has the bypass circuit pop off valve that regulates and limits lift pump pressures. Excess pressure shunted back to intake side.
Just a thought here on those air bubbles. Although fuel cannot be compressed, just like any other liquid it can cavitate when passing over or through moving parts. Just as a boat prop will cause air bubbles to form when spinning in water, moving pump parts (Lift and injection pumps) "might" be creating those bubbles. You've got fewer now with a higher quality pump made with tighter tolerance clearances in the moving parts.
Just a thought.
Yeah I agree with you. After making this video I did some more research, and that seems to be the case. But I was hoping maybe some Cummins 12 valve expert would come on here and school me haha. So I know for sure. Bubbles or no bubbles the truck runs like a dream, so I'm happy about that.
@@NoNonsenseKnowHow picking up a new Precision brand lift pump from O'Reilly for $140. Zero fuel pressure so pretty sure 250k mile Carter is toast.
@@CptJera sweet man. Yeah sounds about right. Let me know how you make out
@@NoNonsenseKnowHow Will do. Should have had the old one off to take the bolts in and replace with studs like yours.
I can see lining all this mess back up is going to be a chore, especially for this not-so-limber crusty old back and shoulders. Working on these big Cummins is a young man's game. BTW, O'Reilly's warranty is lifetime so it's a plus.
@@CptJera yeah having the lifetime warranty is definitely a great perk! You can try letting the air out of the front tires to bring the truck down a little bit and that would help out getting in there. Just make sure that the cam lobe that drives the fuel pump is on its flattest Point. Basically so when you're putting the new pump on you don't have to depress the plunger very much. It's easy to put a scratch in the cam if not careful.
My Cummins was losing fuel pressure over night and I found the feed in the top of the lift pump had a compression fitting with a rubbee grommet leaking air in the system so I took out that line and went straight with injection rubber hose from the fire wall to the pump no more leak
Just replaced my lift pump.Got a "genuine" cummins pump off amazon.Got it,had cummins cast into housing and had the weep hole.But it was made in china.Looks like a quality product.Old pump had 500,000 miles on it.Time will tell if new pump will last.
still going?
@@Precisionmobile So far working good.
The fuel heater can also be burnt out and leaking false air. Best to remove the Fuel heater in 94-97 models.
I got rid of all OEM mechanical fuel pump and oem filter, went to electric Bosch 044 inline pump with napa 3788 fuel filter and water separator .
I prefer mechanical. Something special about knowing that this truck doesn't need batteries to run.
Hi there, when you installed bosch 044 pump did you use pressure regulator?? I have a 6ct 8.3 cummings and I'm thinking about putting the same pump, but with 72psi output maybe is a bit to much without regulator... thanks in advance
@@alenl80 hey i used a aeromotive fuel pressure regulator set at 36psi all the time, another way you could go about controlling the fuel pressure would be a in cab voltage controller.
@@NoNonsenseKnowHow yup!...I have eliminated my fss, fuel heater and installed tcc lock up switch to override any electronic related gear hunt when in od and a starter switch fused direct to starter...I want everything mechanical...less breakdowns on my 97 6bt.
I had a similar problem and found it to be the washers on the injector return lines. small amount of air infiltration happened for me there and new ones sealed it right up..
You replaced your LP because only 25 psi fuel pressure…I thought that’s more than adequate…(that’s what mine runs at)…not good? Also could the overflow valve be bad and limiting pressure buildup?
In regards to the air bubbles in the fuel stream, has anyone tried an AirDog pump with the separate water and fuel filters? Albeit they are spendy upfront they are reported to remove the air bubbles from the fuel. I bought a '79 Jeep J20 long bed with a '95 12v in it; its my 1st diesel ever and is proving to be quite the learning experience. Due to lack of maintenance by the PO(s) it keeps crapping out and dying on me. I've got an auxiliary fuel tank/tool box combo (Handy FT-50-A, no longer supporting this unit) that I want to use instead of the current tank. I'm leaning to the AirDog FP100 to filter and push the fuel to the CDEC lift pump; I plan to upgrade the AirDog fuel and water filters to FleetGuards. Am I going crazy missing something here? I need to get up and going ASAP!
I've heard good things about the air dogs. Never tried one though. Mine has been running like a top since this video so I haven't messed with it. That sounds like a pretty sweet rig you have though and definitely worth dropping some coin on a nice fuel setup.
Cavitation? But that would be on the inlet side correct?
Phillip Cabaniss that's actually a really good point you just brought up. Yeah I suppose cavitation would be possible. I'll have to look more into that! Thanks!
you could have a air leak from one of the delivery valves. a fuel sump would help no matter what
Johnny Appleseed thank you for your input. I was under the assumption that the delivery valves are on the pressure side so would leak fuel instead of allowing air in. I did bypass the injector return line thinking that maybe I had a bad injector seal allowing combustion gases to enter the fuel system. Still have the little bubbles. and as far as installing a sump, I don't think that will help me either seeing as how I bypassed the entire fuel system by hooking a fuelsupply hose directly to the lift pump. thanks again and let me know if you think of anything else
Hey not sure if you looked at the fuel heater yet, but I hear that is source of air. My 96 runs little rough after warm up and I'm hoping it's just the fuel heater. Great vids.
i would try carter+ cant always freeking run a.c.delco 24_7)
My 96 12 started acting up today. It started up and ran fine then started stalling while driving. Now it won't start at all. Checked my fuel shut off was working and it is. I'm thinking it's the lift pump?
You should get a fuel pressure gauge on it
How did the pump hold up?
Did you replace the low pressure return line behind the fuel filter?
You're talking about the big rubber one?
you can add a weep hole
Yeah that's true, but I was afraid to mess with it and destroy the new pump if you know what I mean
How exactly did you go about it ?
My DCEC pump lasted 3 years/26,000 miles....Started getting weak about 500 miles ago, started leaking today. Buy OEM Cummins made in China pump..yes, made in China. Carter pumps are no longer the OEM.
Really? Damn, good information thank you! Mine is still going strong. I agree that the Chinese Cummins seems to be the best option. Guess I'll see how long my dcec pump lasts. Where did your start leaking from?
@@NoNonsenseKnowHow Just my experience, your mileage may vary! GL with it.
My DCEC Cummins lift pump came with a pressure relief/seal failure bleed hole right out of the box. Im not sure why yours didnt but you may have gotten an ebay fake.
Really? I'll have to look into it. Thanks for commenting that
Where did you order yours from?
I get most all of my stuff from a seller i have done quite a bit of business with that goes by dbsales. The owners are Duane and Becky and their prices are always great. I would definitely recommend reaching out to them for parts in the future.
@@NoNonsenseKnowHow they have an ebay store as well as an online retail store as well but I usually just use ebay method to avoid any shipping costs on small orders.
@@Erklzanderz cool thanks man, I'll check it out
witch pump on amazon would you recommend?
My buddy got one of those $35 shinehome ones a few months back and it seems to be working great. I've had good luck with the dcec pump so far
thank you I appreciate the reply
@@Thedave2224 no problem man!
Got a question for you on my 12v Cummins ppump 215 h.p truck bone stock except 90 h.p injectors and a exhaust.
Ok so this is the truck my dad and me use to pull our trailer for our business and he has owned it for some time well recently it started missing so I tossed in injectors seemed like it fixed it drove it and it came back so I checked his fuel filter changed it helped but came back so I put a new overflow for the return in helped but it returned recently I pulled the sending unit and removed the tank screen because it was filthy and I could not find any replacements offered so I figured it's got a filter and I plan to run a custom filter system myself when the miss is fixed once again it helped then went back to missing so I'm about to toss a lift pump in it and see how that works on it since the pump is a 220k pump as far as I know I also ran some of the biocide fuel treatment in the tank and it seemed to help but didn't fix it.
And I have noticed it only wants to miss when it gets warmed up and you either got the trailer and weight on it at low RPM or you put it in 4th gear at like 25 to 30 and gently accelerate and it will do it's bucking but stomp some on the throttle and it seems to go away
is there any direction you could point me to on this problem?
Mine is doing the exact same thing. Did you ever find the problem?
Get a fuel pressure gage so you can see if it’s within spec at high and low rpms. Maybe pressure to low at low rpms to provide enough fuel.Install an new overflow valve they are cheap and easy. Check for air in fuel supply line.
@@thenomad7120 Did all that we put injection pump on it and it fixed most of it but it still had a slight miss i did lift pump fuel filter overflow valve and it had new injectors little before the miss sometime last year i had a moment of clairity #6 injector the copper washer was leaking compression past the injector body i replaced it and fixed it for a little bit but i think my head is messed up in the injector seat so I'm prob gonna have to use a seat cutter on it if i keep it any longer
@@tomhutchins1046 A big part of my issue was the injection pump had problems internally but it still had a miss in a pull and last year I had a lightbulb moment and figured out somehow my #6 injector was losing compression around it from the copper washer being burnt out so if you still have this problem or know anyone else that might tell them to get a injector install kit and do all new copper washers etc aka reseat them my truck it worked for a bit but the miss kinda came back after a little bit and i think my head has some issue with the injector seat but it doesnt really get used atm and it might be getting sold before long
@@nou8257 My issue turned out to be the lift pump after going through at least 3 different brands i found a real DCEC pump (one of the indicators is a small bleed hole were the shaft goes through the housing .) Its designed to basically act the same as a water pump bleed hole. Put that pump on now it holds 28-30 lbs of pressure at idle and runs better than it ever has even on a hot day. Also you have to be absolutely !! sure you have no air leaks even a pipe thread fitting with no sealer will make hard starting after sitting for a few hours. You wont see a leak . The quick disconnects next to the bell housing are known issues cut them out and replace with very high quality plastic lined rubber hose or hose designed for diesel marine use.
Yes i bought injectors and all kinds of things but that was not the issue.
Is the DCEC a 30mm and the Carter a 26mm piston bore?
I'm not sure
Go fass
you dont mention that the shitty made in USA Carter has a much smaller piston by about 1/8 th "..and you're right that Carter is complete shit.
I didn't realize the Piston was a lot smaller. Did you measure them? Thanks for bringing that up
i had both side by side on my bench yesterday,and measured them quickly,about 1/8 th on an inch smaller.
Just get a FASS
