Engine/Transmission (1998.5 - 2002) the 70 dollar lift pump

[PatrickHenry]

I used the ($70) lift pump from a local cummins shop. I think I cost me just a little over 70 bucks. I just went in and gave them the part #4090046. They ordered the part and a couple of days later I had a lift pump and some other unneeded parts (I think they could be used on a low pressure warning light, but I'm not sure about that). I just tossed them and drove on!!

I called the local Cummins dealer here in Milwaukee WI and they said that they had the part in stock for 70$ and change. I told the parts guy that I would pick it up on the way to work and they called me back 10 min. latter and said that they couldnt sell it to me because it was a recall part. I guess I will be calling a more customer friendly dealer that will take my $$$.

I need a summary of all this:

I just got back on to TDR after 2 yr. absence and found this thread. I have read thru a lot and want to see if my summary is correct: First, I have 98. 5 4wd quad cab 5 speed with 110k miles. the injector pump was replaced at about 85k miles, lift pump was working fine, but had been replaced 1 yr prior under warrantey. I figure it damaged the vp44 & took 9 mos. to go out. They would not warranty the vp44 unless they replaced the lift pump. So, am on the 3rd lift.



If I understand correctly, the procedure now is to fully remove the lift pump and install a new pump in the tank, instead of installing a booster pump outside the tank. Is this tank pump the one that is priced in the $50 to $70 range and can be purchased from Cummins or auto supply houses?



What does the entire kit cost to change over to it. I have never liked pumps in the fuel tank & would rather mount a booster outside the tank, but understand that if I get into real cold weather, it could be a problem.



I want to be prepared for when the lift pump goes out again and don't have gauges yet. Is this tank pump the best way to go, if I understood it correctly?

The in-tank pump is "not" the best way to go. . but it "is" what DC will do if they change the VP44 under warranty.

The $70. 00 LP everyone is talking about is the OEM Carter pump replacement and you can find them at a Cummins shop. Some Cummins dealers, however, will not sell you the pump unless you're an authorized Cummins repair station or some such thing.

The Cummins shop I went to handed me the pump with no questions. Guess it just depends. Check around and you should find one.

The $70. 00 pumps are for a Cummins campaign that involves fire trucks & buses. It's too bad the Dodge problem couldn't be a campaign.



I was able to purchase 10 of the pumps initially from the Cummins dealer. A month ago, I tried to buy some more & Cummins wanted engine serial numbers & VIN numbers.



I put one of the campaign pumps on my truck in July, and it is getting weak already. Fuel pressure @ idle is 12 & if I get on the throttle, I can drag it to 3 psi. I got a FASS sitting on the tool box, hopefully I can install it over the holiday weekend.

Campaign Pump

I put one of the campaign pumps on my truck in July, and it is getting weak already. Fuel pressure @ idle is 12 & if I get on the throttle, I can drag it to 3 psi.

The pumps mounted on the engine, 6 to 8 feet from the tank, and having to draw fuel uphill all day are a failure waiting to happen.

There's no doubt the carter pumps aren't the best in the world but if you mount it down on the frame, close to and below the fuel tank, and let it "push" fuel your odds go up. Also, when it's mounted on the frame replacement becomes a snap. I could change mine out in 5 minutes and be back on the road. The OEM mount was a PITA.

I'm wondering if I could add one of these pumps near the tank using Geno's relocation kit and leave the original pump as is. Would 2 pumps in tandem be better than one?

 

[BK]

Original thinking back a few years was yes.



But from what we know now, the original pumps did not have a bypass in them.

So if it stalled and or failed, the VP44 will starve for fuel since fuel maynot get passed the old bad pump.



The newest design is "suppose" to have a bypass built in.

So that if it stalls fuel can still be pulled passed it via the VP44.



So safest thing to do seems to be, get ride of the old pump on the block all together.

Mount a new pump on the frame rail. Where it's also 100% easier to replace if it goes bad again. . or put something like a FASS there.

Funny you mention the Carter pump. I just talked to Carter pump & they said that the pump was never designed to be a suction pump but only a pusher pump & that the max distance from the tank was to be only three feet. We are all at least 6 ft & using it as a sucker. Wake up DC

 

[BK]

Yup, back in 99 or 00 when the LP failtures became such a noticable problem, research was done and that same exact fact was discovered here on the board by someone else.



So for 6 years or so, DC hasn't woken up (why it's such a sore subject), acknolwedged it or nothing, untill now with their in tank fix that no one will trust.





And Cummins finally got into a recall with the pump since it became a safety issue with stalled trucks and busses... hence the new pump and low pressure switch.



Cummins' agreement with DC does not include warranty. . so hence the recall does not apply to our trucks.

 

[Silver_Ram]

I finally got my FASS II pump on, I haven't been able to pull the FASS down to the psi, that my $70. 00 idled at. I capped the old system for a emergency back up.



Nio more tiny lift pumps for me.....

Will This Pump # 4090046 Work On A 03 Ho Engine???i Don't Want To Get The Wrong One, Also Will It Bolt Up Where The Present Pump Is???? Tks Doc

Hey doc, the 4090046 pump will not bolt up to factory location on my 04 HO. But this pump is a good candidate to put on the frame rail, and run in tandem with the pump that came with the truck. Because it has a bypass valve in it in case of failure. I am planning on putting it on my 04 sometime in the future, and running separate wiring.

This is the 2nd gen pump, the 3rd gen pumps (located on the filter housing) are $300 from Cummins (and you can still get these through Cummins, even though DCX only offers the intank replacement option)...



I thought long and hard about carrying an extra pump, but at that price, even the glacier kit (and FASS or Airdog for that matter) are within reach.

Thanks Bw, If You Can Get Out Of That Snow Drift Out There In Wyo,, Why Dont You Come Down Here In Kansas And Put Me One On This 03 Of Mine????of Coarse There Might Be A Bit More Traffic Down Here And That Might Present A Problem To You As I Dought You Seen More Than 3 Vehicles In Your Life In ??/(where's That Place) Bar Oil????wyo???

Pretty much, got somewhere between 8 to 10 inches of snow in the last 2 days. All three cars in the state were stuck! :-laf

I sent a friend to cummins with the part # on tuesday and understand the parts man told him this part # is no longer valid... .

 

[CFast]

I've been running a Carter fuel pump from SummitRacing for the last 3 years with no problems. It wasn't a $70 pump, it's $115. 95. It puts out 18psi and 100gph. It's worked great for me. I mounted it on the frame rail about 18" in front of the tank. My $. 02...

JKinney,



The Pump Campaign that provided the cheaper pumps may be over now.
