Engine/Transmission (1998.5 - 2002) need factory lift pump advice please

[BBate]

Well today I purchased a new lift pump from cummins in Bristol. $150. 00 same price that I was quoted at freightliner. I installed it today. Also I drilled oversize three banjo bolts. I went from having 3 pounds at idle to now having 12 pounds at idle. I haven't had the truck back on the road yet so I don't know what my wot poundage is yet. Hopefully I'll have all my power back now ... ... Bill

It's not a matter of the pressure dropping. This is what is happening. When idleing I have heard the pump making a differant sound and notice that the pressure is down around 7-8 psi. Once I accelerate down the road it will come back up to the normal 12-13 psi. This is not consistant though. It may not do this again for quite awhile. While cruising I have never notice a pressure drop. The last pump did the same thing as this one. Put this one on without changing the fuel filter and have had no problems until about a week ago.

That is most likely due to a voltage drop when the grid heater cycles, mine makes the change in noise too, much more noticeable once you are sitting on top of it, although usually the pressure doesn't drop much. Getting ready for my yearly change out, AGAIN!

I just dont understand how anyone can keep buying these oem lift pumps. I went thru 4 including two campain pumps. The walbro pump is pumping a steady 16 lbs idle, underload, full throttle

Better direct oe lift pump replacement

MAV1, until some numbers are posted, regarding this Airtex pump, I'm remaining skeptical, based on my experiences with the company. I'm not trying to be jerk about it, but I've seen too many posts about how a product is super new and improved, yet ultimately proves to be a dud. Airtex themselves admit that they were getting back their rebuilt Carter pumps, because they were crap. The two Quadrajets I got from them wouldn't stop leaking, and if I read Gary's post correctly, this Airtex designed pump is just a knockoff of the one used on a Mustang.



What I'd like to know is why some factory OE Carter pumps can go as long as mine has at 112,700 miles, while others crap out at 19,000 miles... is it the way the operator uses the truck? I tow an 31' Airstream, a 26' Gore steel Thoroughbred horse trailer and an 18' Bass Tracker. I keep it in 6th on flat ground and lower gears when it needs it.



As for the Cummins part #4090046 pump, what is the difference in design from the OE Dodge Carter pump, aside from the price? Does it mount and perform the same way? Are the fittings, both electrical and fuel, the same?

 

[MAV1]

Oh well

:{:{:{:{ Remain skeptical all you want, you have a problem with Airtex, that's your problem. For the umteenth time, I've simply tried to point out that for those of us that want an oe type pump in the oe location, there is another choice, and I believe a better one.
As for your questions about longevity, that is the million dollar question. You figure that one out and all of this goes away doesn't it!? In my own experience, having had 8 lift pumps counting the one on my truck when I bought it new, I have seen three defective right out of the box, they ran but no pressure and no fuel, of the other five, I have seen one that was what it is supposed to be, i. e. , 16psi at idle, around 12-14psi at cruise and no less than 10psi under wot. The rest were low on both pressure and volume right out of the box. As for your slam on Airtex and your comment about rebuilt pumps, no one is rebuilding them. They are not re buildable. Reread the post. The Carters contained in an Airtex box, were repackaged new pumps, Airtex purchased from Carter, and resold with their label. Period.

As for the p/n 4090046, do your own research and study, I don't have the time or the inclination to rehash what has already been posted on the TDR till the cows come home. Hint, a carter is a carter is a carter regardless of who's p/n is on the box. The new pump I have advised of is NOT manufactured by Carter, it is manufactured by Airtex, through their engineers addressing the known shortcomings of the Carter, including the worst one of them all, **** POOR QUALITY CONTROL.
In closing, you want to bash and have a hard-on against Airtex, that is your privilege, you have stated so many times, however no one is pointing a gun at you, forcing you to buy/run one of these pumps. As for figures, they will come out in due time, just as numbers came out for the others as they were put in service and people gained experience with them. Sfrey is installing these pumps, and I am in the process of installing some, on on my own truck and on some friends trucks. With the photos of Sfrey, adapting these to frame rail location, I am waiting on a machinist that is making the needed adapters for me.

You've made it clear you have no use for Airtex, here and elsewhere, now stop flogging a dead horse and grow up!

Ditch it and get an aftermarket located closer to the tank. The latest fix from Dodge is the in-tank POS - MHO go aftermarket . . .

 

[FLynes]

Actually, what I said was that I purchased two rebuilt Quadrajets from Airtex, and both of them leaked. This is not a bash, it's a plain fact. I'm pretty sure that anyone who would have had this experience would be skeptical of buying another product from them.



You're the one who initially posted that the Airtex pump is an end-all to the Carter pump. Believing that it's better and knowing that it's better are two different things altogether. What I'm asking is for numbers to prove that this is a better product. If Gary is right, and this is just a repackaged Mustang pump, my first question is does it deliver the fuel our trucks require? I'm NOT saying that this Airtex pump is an inferior product; I'm just as frustrated as everyone else that DC put these pieces of crap on our trucks.



The difference between you and me is that you are probably more monetarily comfortable than I am; I'm in the Army; I don't make enough money to throw at a fuel system that touts itself to be better than OEM, especially something like Glacier, FASS, Airdog, etc... , so I pray everyday that my OE Carter will keep on keeping on. If indeed the Airtex pump does what it's supposed to, great; I'll use it as a replacement the day my Carter goes TU.



As for growing up, check a mirror. 17 years in the Army has given me all the growing up I'll ever need. When you get into a combat situation and your friend's HMMWV hits an AT mine and the only thing you can do is hold him as he dies in your arms because he's missing both legs, come talk to me. I've put my life on the line, eaten lousy food, taken cold showers out of a Gatorade bottle more times than I care for and humped an 85lb ruck on my back for miles on end, while you sat at home relaxing in your recliner, pounding beer and eating steak, taking hot showers and playing with your truck; I think I've earned the right to post my opinions, respectfully.



You get on the defensive as soon as someone posts something which you don't like. It's your right, since you live in a country that is free.



You're welcome.

Gary isn't right, anybody with a pair of eyes can see the two are not similar, outside of shape.

As for defensive, don't dish it out if ya can't take it.



I've been there done that, it was called Vietnam, thank you.
You're welcome

Vietnam? I was there too. 1998, to find the remains of those left behind. I humped hills with heat topping 104* and 100% humidity. I was in Quang Binh and Quang Ngai provinces. I flew on crappy MI-17's flown by drunken Vietnamese Air Forces pilots. I stood on what was left of Holloway Air Base, in Pleiku. I explored Marble Mountain, in Da Nang. I was in the A Shau Valley investigating a CH-54 Tarhe crash. I was in Kham Duc recovering the remains of 12 SF guys who were annhiliated by the NVA and VC. It was the most rewarding 6 week mission of my career.



Yeah, you guys had it tough, no doubt about it, depending on your MOS. I do thank you for your service, MAV, but I still stand by what I said; when I see the proof that the Airtex pump is more reliable than the Carter pump, I'll get one. Nuff said.



By the way, I can take it as good as I dish it.

"Gentlemen, AT EASE!" and, thank you both very much for defending our beloved country - seriously, both of you have points of valor, but morso share a kindship of service to our country - with that in mind "can't we all just get along?" Sorry, I just hate to have two brothers in arms arguing. I was in the Navy 5 years, Machinest Mate 2nd class (E-5, hole snipe duties, Auxilliary division home) 80 - 85, the Regan years, I didn't see any action, spare a mortor being launched at my ship bringing us to general quarters as we sat in the bay @ Beiruit, two weeks before the embassy was bombed that killed a bunch of our young commrades. On a gator freighter (USS Raleigh, LPD #1 - rest in peace my ship - used for "testing" in 1999 I think) we were part of the 1983 Multi-National Peace Keeping Force, we transported Marines & their equipment within 1 - 2 mile of the beach and ballasted down in the water as they drove tanks and other amphibs off the stern gate into the water and resurfaced, making their way to the beach.



Anyway, FLynes - since you are in the Army - I can relate to the gobbs of money you must have (not) I'm not sure where you are presently, hopeful it's state side, see if you can hook up with one of the Army welders and have him make you up a bracket to mount your pump back on the frame closer to the tank, extend the two wires from the present location back to relocated pump, cut the fuel supply pipe and hose over to the newly located pump and then back to the line going to the Filter/VP. Making the pump function as intended to do the job for the type pump it is - a pusher, not the puller that it is trying to act like in the present location. At least that will get you a bit more life out of it till you can save some $$$ to get the system you desire.



Be careful out there bro . . . come home safe, a men!

 

[maxburk]

I have a carter pump you can have. It has less than 2k miles when I installed a Holley Blue pump. I hear a lot of chatter about other fuel systems but the Holley BLue is doing the job for me. If you want it I will drop it in the mail Monday. You can pay the shipping if you want.

 

[VHolloway]

go with the fass II pump

I get 19 at idle 17 on the open road with a big load

just get the fass pump you still have the stock fuel filter on the engine

the fass II pump the way to go
