In-tank pumps on gas vehicles is pretty much all that has been used for the last twenty years and in some cases alot longer. I would sure hope to see some failures as you would with any mechanical part OEM and aftermarket.

Superduty,
Lets just say you have a dog in the hunt????? I remember the days when everyone went around saying the dodge 47RE transmission was a piece of junk and prone to failure. In 2002 or early 2003 there was a study about transmission failures from the big three diesel applications. Chevy allison had the most, Ford next, and Dodge had the least. I find out later that alot of the rumors being spread on these types of websites was mostly from vendors trying to drum up business or a friend of a friend type crap. The TDR was a great example.

roadranger,
I've heard about the 06 from superduty on a different thread and am trying to get ahold of the guy for more information. The 2005 him and you are referring to I still can not find.

I do see alot of speculation on many threads about people referring to the lift pump going out on the 2004 and earlier models but those are not in-tank lift pumps. I think the in-tank lift pump is getting alot of bad rap because of the engine and filter mounted lift pumps. I see it all the time, some one will post something is wrong with their truck and right away people will come on and say it's the lift pump only to find out later it was the APPS or crank sensor, or cam sensor, or IAT sensor, or MAP sensor, or a shorted wire, etc. etc. Don't get me wrong the 2004 and earlier electric lift pumps used by dodge were and are junk. Just trying to find good crediable information on the 2005 and newer in-tank lift pumps. If it turns out they are junk I'll be the first to pass on the information. I can not tolerate crap information being spread!!!

This thread was to find out if in deed there is a problem with the in-tank lift pump in the dodge application not for someone to speculate there could be because they had to change one out in an 18 year old car. Just using that as an example. Not trying to insult anyone

 

If you haven't reread my first post in this thread, Please read it.
I updated it today.

 

I have a mid year 2003 truck. I have the filter mounted lift pump and I've been running for almost 50K miles so far with no issues. What is the life expectancy of the filter mounted lift pumps? Are they REALLY failing at a high rate?

Personaly, I don't like the idea of putting the lift pump in the tank simply because it's a bigger pain to change. I would think that with all our advances in technology, we could make an electric lift pump capable of sucking diesel fuel 15 ft. for 300,000 miles without major failures.

 

I really don't want this thread to become a question ask and respond type thread. I just want to know if the in-tank lift pumps are having any kind of failure rate and if they are just a brief description of the symtoms.

Berak, The fuel filter mounted lift pumps have had a failure rate of what % I do not know and I think no one really knows. Lets just say higher than normal or one would expect. Too many variables to get a good number. Thats why I did not post this thread as a poll. Any one could just make their mark and not have to be identified. They could have construed the outcome just because they had a bad day, or broke up with there girl friend, or hated a dealership, or disliked the service person or just plain have a grudge against whatever reason.

I just made a post in the other thread started by me. in-tank lift pumps truths, myths, speculation, and lies.

 

back to the top

 

I have had a couple trucks come through with 140-150k on them and they still have the filter housing pump on them.

 

So if my filter mounted pump dies, I can't replace it at all? I have to get the new in tank model because they quite making the filter mounted one?

That kinda sucks, because if it's a part that's going to fail every so often, I'd rather just swap it out on the filter housing.

I think if my stock unit dies out of warranty I'll try to put the Walbro or Aeromotive in-line in the stock location (on the filter housing). And use the factory wiring. Wouldn't this be pretty straight forward conceptually? The tock unit only get's activated when psi drops below some number right? I shouldn't need an additional regulator.

 

Berak,
Since you have already hi-jacked this thread and don't understand the operation of the fuel system, let me try to help.

First, the fuel pump runs all the time that the engine is running.
Second, the only pump that will fit on the filter housing is the orginal stock pump.
Third, re-read all the threads about replacement fuel pumps and understand what is going on. If and when you replace your pump, make sure that either it is self-regulating at about 15psi or that you have a regulator installed that will regulate the fuel pressure at 15psi.

P.S. I would rather be on my back, in a mud puddle, on the side of the road, replacing a "replacement frame mounted fuel pump", then standing on the bumper, laying across a hot radiator, trying to replace a filter mounted pump by "feel". Believe me, once your hands are all over the filter mounted pump trying to find/loosen/replace four 1/2" long screws(5MM allen socket a 99% requirement) in the vertual dark, you will understand

 

First off I don't feel I "Hi-Jacked" this thread as almost everything were talking about, replacing the stock unit, applies to an engine mounted or in tank pump so your continued harping on this point is groundless. If I don't understand the working of the fuel system it's from reading the threads you've tried to point me to re-read. Someone in one of those threads stated the pump is only activated when pressure drops below some amount, and I didn't see anyone correct him so I assumed he was correct. Apparently he wasn't, that's fine. I guess I'll have to take your word on only the stock pump fitting the stock filter location since I haven't examined and measured it for comparing whereas you must have seen every after market pump available and made sure it won't fit on a stock filter location. That's cool, thanks for all the hard work.
