3rd gen lift pump failures
Yes and the truck is stock 15 10.56%
Yes and I run a box 8 5.63%
No truck is stock 73 51.41%
No and I run a box 46 32.39%
Voters: 142.
16.2% of all trucks have had the pump replaced. A little more than 1 in 6 trucks.
Replacement rate on stock trucks is 15 of (73+15) = 17%
Replacement rate on mod'd trucks is 8 of (46 +8) = 14.8%
Like I said, the mods shouldn't make any difference in the lift pump failure rate and the stats seem to bare this out. Idling and running the pump with the engine isn't running are probably the worst thing for the lift pump.

In Alberta we have a 99% failure rate before 100 000 km .Most are around 700 hours . As soon as the cold weather hits we get bombed with lift pump failures; 2 or 3 a day on average. That is why we were/are installing the retros before the canister mounted ones fail(its not fun to push 1 ton welding trucks into the shop when it's -30). I see 0% failures on the 05's and the retros.

Would you happen to know the specs and what part number that might be?
I don't know what they are formally. I think it stalled out at 70 PSI (versus over 100 PSI on the Walbro). The flow rate was lower than the Walbro too.
Look under a 99+ Ford Superduty or go to a Ford dealer and get a pump from their parts department. It says Bosch right on it. It has a part number too. I don't have my old one anymore.

0% failure on the in-tanks, time will tell for sure but looks promising.
1. Do you know if the in-tank pumps have a bypass or relief built into them or some other way of pressure relief?
2. Is there an anti-siphon of some kind to allow fuel to be pulled through the pump in case of pump failure?
"That information would support what was said earlier about the different quality of diesel fuel having something to do with it."
The quality of the fuel has NOTHING to do with it. All that is happening is that cold fuel is harder to push through a filter because it is more viscous. The pumps aren't up to the task and they fail.
Everyone blames fuel when something goes wrong. It is RARELY the cause. Like 1% of the time. Diesel fuel is diesel fuel from Alaska to Florida. Cetane and viscosity vary a bit, but nothing that will cause issues like what people like to talk about. Do you think 100% of the Freightliner lift pumps fail before 60,000 miles in Alberta ? I doubt it.
There are several examples of lift pumps failing on 05 trucks here and on other boards. I don't think the in tank pump is a cure all either.
"Is the Walbro pump better than stock? Maybe."
You need to take apart a few fuel pumps, read my posts and then compare the fuel pump failure rate of Fords versus Dodges again.
I find it very interesting that people are so cavalier about this issue, especially since it appears that a couple members had their Christmas holidays messed up due to lift pump/ CP3 issues. It isn't just the lift pump we are talking about here, it is the CP3 as well. I don't think people understand that yet.

Could you point me to those threads?

I dunno what the Frieghtliners use. Google might tell you. So would a call to a FL dealer.
Here is an 06 with a pump failure.
http://dieselram.com/cgi-bin/ultimat...;f=29;t=005119
=================================================
Do not feel bad about your lift pump, mine crapped out at 6,000 miles and is one of those new in-tank deals. I now have a HD in-tank pump from Detroit Diesel made for an over-the-road truck.
--------------------
2006 Megacab, 4X4, 6 speed, lifted 8", winch, bumpers, kitchen sink is next. I grabbed it by the horns, and it grabbed my wallet!
=================================================
This guy probably has a CP3 or lift pump problem. All it would take is 5 minutes with a scan tool watching desired versus actual rail pressure, FCA duty cycle and lift pump pressure. Could be a failing APPS too.

http://dieselram.com/cgi-bin/ultimat...;f=29;t=005106
I don't know what the cut off date for the in tank pump was.
http://dieselram.com/cgi-bin/ultimat...;f=29;t=005087
This one is classic. New 06 truck and it long cranks, has no power and smokes. Guess what ? It doesn't have any friggin rail pressure. Put a scan tool on it and take it out on the road. Could be CP3 or lift pump. Maybe rail pop off valve.
http://dieselram.com/cgi-bin/ultimat...;f=29;t=005143
There was a rash of them on dieselram about a week ago. I don't have time to read through them all.
Google works wonders for these sorts of things. I don't have a membership at TDR so I can't see those. They often start out "my truck won't start" or "my truck died".

Lost mine last winter at around 20,000km. Located in Northern Ontario, and lost it in late January last year. I support the cold weather idea myself. I don't think it matters what kind of fuel it is, at -30C it's gonna be pretty thick. BTW, there's a fuel heater in the system somewhere apparently, I suppose it's downstream from the lift pump??
The fuel heater is in the bowl. I think it is downstream of the pump on both setups.
Was yours an in tank pump or on the engine pump ?
The fuel heater is in the bowl because warm (err... not cold) fuel goes through the filter easier.
The poll failure rate is 29 of 163. About 1 in every 6ish trucks. Kudos to the poster who did the poll.
10 years ago you guys would have never known lift pumps were a problem unless a bunch of you got together and started discussing it. The power of the Internet. I wonder if the Dodge boys visit this site ? I wonder how Dodge can have lift pump problems year after year. Same guy designing the system ? What would it take to get fired at Dodge ?

Link 1. verdict is out yet, still getting information from him.
Link 2. His problem is more the APPS. If the lift pump was shot the truck wouldn't run, his still runs with low power.
Link 3. States nothing about in-tank lift pump failure.
