They sell a fuel pressure alarm for about $55, and it is easy to install. The way it works is when your fuel pressure drops below 5 psi an in-cab led will light up telling you your fuel pressure is low.

They also sell a oem bypass lift pump kit that removes your stock fuel pump, and mounts it by the fuel tank.

Give them a call, they are really easy to work with.

 

There is absolutely no reason to be recommending a cam operated pump. All the modern gasoline engines use a high quality fuel cooled gerotor pump running at 50+ PSI and 40+ GPH, more than enough to feed a Cummins at 25GPH and 15 PSI. Why would you even consider putting a cam operated pump on the engine ? For $100 you can buy a good EFI pump and solve this problem forever.

And how many times have I said to throw those stupid carburetor pumps in the garbage where they belong ? Funny, we get a spate of cold weather and here we've got CP3s leaking again.

A 3rd gen Dodge gasser has a fuel pump that feeds the fuel injection rail at about 60 GPH and 60 +/-2 PSI. You don't see them failing, do you ?

This guy has the same problem.

Dodge is having more problems with the CP3 than maybe any of us know. The problems are difficult to diagnose. Industrial Injection just invested mega bucks on a machine to test and calibrate them. They are figuring they'll get plenty of business from dealers who are getting tired of arguing with STAR over wether the pump is bad or not.

 

Yeah sure, and there is NO difference between gas and diesel when the temp starts to drop. C'mon Superduty, yer pullin' my leg! I KNOW your brighter than that.


Look at the guys location, Stephenville TX. Its a pretty safe assumption Grandpa ain't drive thru the Yukon or on the AlCan this time of year.

 

"Yeah sure, and there is NO difference between gas and diesel when the temp starts to drop. C'mon Superduty, yer pullin' my leg! I KNOW your brighter than that."

You guys just don't get it. The Cummins lift pumps are feeble. The in tank models make 10-15 PSI when it is warm out and as soon as it gets cold the pressure drops. That gasser in tank pump makes 60+/-2 PSI. If you mounted it on your Cummins truck (with a bypass of course) it would supply the CP3 just fine when it needed 15 PSI and when the going gets tough (cold fuel, dirty filter, etc) and it needs 20 or 25 or even 30 PSI it would STILL do just fine. The gasser pump is built for 60 PSI. It ain't going to slow down or have any trouble with "thick fuel" that needs 20-30PSI to get it through the filter.


Dodge Cummins truck owners think that diesel fuel is so hard to push and they think their Cummins is so hard to feed because they keep using carburetor lift pumps designed for 10 PSI. In reality the Cummins is the easiest modern engine to feed and most EFI type lift pumps will laugh at 30 GPH at 15PSI. The Bosch lift pump in the 99+ Ford Superduties pumps the same diesel as what Dodge trucks use, in the same climates. It runs at 50+ PSI for years and years.


I didn't say his was weather related. Maybe he allows his filters to get dirty or maybe he has a marginal lift pump that hasn't been diagnosed. He is on his 3rd CP3.

 

I think this subject has been beating enough

Superduty, don't you feel like this horse sometimes. You sure due take your share of lickings.

Hang in there.

So everyone just pony up the money, and buy a really lift pump and be done with it. I don't think DC will ever get it through the thick skull on the lift pump issue.

 

Darn "Superduty",...........are you back over here AGAIN??? I thought you took your "show" over to www.cumminsforums. com??? Nothing personal, but I was kind of hoping you would stay over there for awhile!!
You know, I think you have made your point over here, why don't you just let everyone decide what is best for THEM?? O.K. Superduty,...... now you can P.M. the moderators and complain about me and "no_6_oh_no" to see if you can get us thrown out of here because we disagree with you!

BTW,.....if I want to recommend or comment on the cam operated pumps being successfully used on alot of the 2nd Gen trucks right now I WILL!!
So as I told you before "Don't tell me what to do Superduty!" You don't run this website!

no_6_oh_no:

A little friendly advice for you on Mr. Superduty. Don't waste your precious time even trying to talk or reason with him! I found that out the hard way! As you probably know, with him it is: "Superduty's way or the highway, that being, a Walbro or a Ford PSD Lift Pump!" Everything all the rest of us are running are junk according to him including (Holleys, FASS Systems, Air Dogs, Product Engineering, Aeromotive or whatever! And this is even though many of us have had these various pumps on our trucks for years! As I tried to tell "Superduty" in in his thread "What is so great about the FASS?" I want to see a "track record" on his Walbro Pumps (other than his own) from not one, but many DTR Members on the Walbro's before I will make a change. IMO, he just doesn't respect anyone elses opinion or experiences.

Well said John.
Great post and I totally agree.

In fact next time I see you, lunch is on me!!

 

Sorry my pump failure landed in the middle of a minefield.

I've been trying to read through some history to glean facts and I'm missing something. One person notes running a alarm to trigger if FP drops below 5psi. In another place I see the claim that a CP3 can run as long as there is adequate fuel flow to feed it, even at near 0 psi.

If I put in a gauge, what pressure should I look for?

I'm still wondering how I keep my third cp3 alive longer than the last 2 combined...

 

Ask John. He has all the answers.

 

Justin:

Thanks!

My apologies to you for getting in the middle of you attempting to gather information from the members on your CP-3! That was not my intention.
FWIW,.....there are alot of members down here in my area (including my son)successfully running the Holley Blues, FASS, Air Dog Systems in their 2003-2006 Dodge CTD CR Trucks with little or no problems at all, contrary to what some will say here!

Also, you asked about "what pressures to look for." On my son's 2004.5 Dodge CTD CR, when his truck was COMPLETELY STOCK he saw right at 7-8lbs. of presssure at idle and at WOT it would drop down to 4-5lbs. I have seen that vary somewhat from one truck to another, but that should give you some reference numbers.

Hope that helps you some, and again, my apologies to you. Good luck with your fuel issues on the truck.

Superduty:

Kind of like the "pot calling the kettle black!" Just "for the record", YOU were the one who started all of this both now and before! Like I said,
"You have made your point, given your opinion, disrespected others,......now just let everyone decide what is best for THEM!!" Hey,......... I think I hear the www.cumminsforums.com site calling you back!

 

No offense and no flames intended,... but Superdutys setup is indisputably better than the original Dodge setup and it will supply the CP3 with adequate fuel for a long time in just about any condition. These are facts. No one can argue the facts. It's better than Dodge's setup.



Therefore, it is worth mentioning on this site, just like a mechanical pump setup is. They will both work, but Superduty's setup costs less to implement and takes less time to install. If you're a die-hard mechanical pump setup person, go with it but from what little I understand about them it will cost more. Fact.

Like I said, no flames intended, just an observation.

 

John....Please chill. Superduty.........please chill. I want to hear both of your opinions without this turning into a finger pointing, argument session.

I am trying to educate myself on what set up to put on my truck. I am looking at all options......Wallbro, FASS, Rasp.......and I need input from anybody that has some expertise on this.

Can we not just express an opinion about a topic and leave it at that? Geesh.

 

It was looking like that to me... but I have not been able to read enough to figure out the claimed pros and cons and evaluate if the claims seem legit or not. At this point I'm investigating my options for a gauge (I hate to speculate about what my FP might be, I'd rather know). I'll have a new CP3 next week, then I'm pulling my 10,000# FW 2,000 miles the following week... no time to even consider getting a new LP setup. I might be a looking for the rumored kit when I get back from vacation.
