Hey I read it on the internet so it must be true.

 

Thanks Jammer. No offense taken and each to his own.

I've spent WAY, WAY too much time on this stuff. I saw some frustration with lift pumps over Christmas and I decided to jump in with some new views. I am going to say my piece today and maybe tomorrow and get the heck out of this.

People can put me down and yell and scream and call me names all they want. It really doesn't matter to me. I am just trying to give people some new information. Others are welcome to disagree.

 

Killer Dowel Pin removal? What's that?

 

SD...
I've been reading quite abit about your Walbro pump on your Ford/Cummins. Maybe you can give me some quick advice. I respect what you've done and what you've said about the stock pump setup on the Dodges'. I have an 05' with intank pump. Is there anyway that you think i can engineer a similar setup to what you have while leaving my stock pump in the tank and operational? I agree with you that I shouldn't wait for a problem and I'd like the added insurance of the extra pump feeding my CP3. Thanks in advance if you can help.

The blocks are assembled useing dowel pins in certain area. Under the timeing chain cover on the earlier blocks is a dowel pin used to line it up for faster assembly at the plant. On some of the earlier blocks (mostly pre 2000 because a few have been reported on 99 models) that pin has worked loose and fell into the timeing chain area causing blocks to break a chunk out.

 

[QUOTE=Superduty I'am not conceding a darn thing with respect to warranty. If I owned a new Dodge truck I would have a replacement lift pump on it the first week. Why wait for something to fail and damage the CP3 and then try to get the dealer to understand that. Why not PREVENT the problem in the first place. If the lift pump got into the reference about warranty denial at some point in the future, I am VERY sure I could come up with a few good arguments about why it ENHANCED the longevity of my engine rather than worked to its detriment.

As far as I am concerned, if there ever was ONE mod you would want to do to save you and your engine grief down the road, this would be it. Save maybe the Killer Dowel Pin removal.[/QUOTE]

You just don't get it, I'am not talking about you and what you would do. I'am talking about you trying to make people paranoid enough about the lift pump problem that they throw all caution to the wind, install an aftermarket lift pump, anyone preference there and void their whole drivetrain warranty.

You can come up with all the arguments you want with DC they have alot more money and time then you do. Will you help the people who got there warranty voided because you said, how can DC void anyones warranty for helping DC with a problem they know they already have. Not your exact words but you get the picture, I think????

I partially agree with you if the in-tank lift pump proves to be no good. Hell your arguing about something that hasn't even been proved or disproved.

Already in the thread you have a guy paranoid about his in-tank lift pump. Man is he going to be ****** for spending money foolishly a few years from now if the in-tank lift pump proves to be successful. Then again if the in-tank lift pump is junk he has his warranty to take care of him for 7 years or 100,000 miles on the 05's.

People justify unnessiary spending all they want but if a problem does not exist why spend it. Thats like saying," your wife is going to cheat on you and desert you one day so you better get rid of her now.

My dog might bite some one some day so better get rid of the dog.
CP3 might crap out on me some day so I better get rid of dodges setup and install Chevies.


Why fix anything if you don't know it's broke.

 

It is a free country.

People can decide to do whatever the heck they want with their lift pumps.

I am not forcing anyone to do anything.

If you disagree, put up a big "Don't touch your lift pump" post.

 

Superduty,
Your high pressure walbro setup has me concerned. You say there is no need for a pressure relief because the unused fuel goes back to the tank, the cp3 only uses what it needs.

What about the fuel filter. Your pushing 60+psi through a filter that was designed for 0-16 psi or a little more. Now add in a plugging fuel filter, then add in some guys hardly ever change their fuel filter, or they get caught up in something going on in there lives and forget to change the fuel filter, or a fuel filter gelling. Now you have a fuel filter designed for 0-16 psi blowing apart from too much fuel pressure. That will kill an injection pump along with the injectors.

I also read on one of your posts about the in-tank lift pump not having enough psi for the vp44 injection pump. It's volume (GPH) your after not psi. DC went away from psi testing back in 2002, they go by volume (GPH) testing now. If the GPH are adaqute for an injection pumps design specs then throwing more fuel at it relatively does no good. I know a person could have the same senerio as my previous paragraph were the filter starts to plug and not enough fuel can flow through it because of low pressures. In this situation the truck would show signs of lack of power to indicate something is wrong, rather than in pressures being too high and no indication of any problems there by you preceive nothing is wrong until your injection pump and injectors are trashed from a blown up fuel filter.

 

I'm not going to fight with you bluebull.

You seem to have an agenda to attack me. Go ahead. Attack me. Call me names. Call me a liar. Call me a cheat. Tell me I'm dumb.

I'm not spending another minute discussing anything to do with lift pumps with you.

 

Superduty,I have been following your posts.I think you as many others on this site have great knowledge and I for one respect that.Please keep the posts coming.I had the Fass system (150 GPH) installed on my truck about 8 months ago,so far so good.coobie

 

Super Duty, don't take your toys and play somewhere else just yet.

You have a lot of educated sounding stuff to say and I rather enjoy the reading.

I don't have an in-tank, don't know anyone with one and don't ever think I'll a have the need for one. That is the topic of the thread isn't it?
There is a thread on 3rd gen lift pump failures, I feel like this is more braodly directed to inlcude the guys that ended up with DC warranty work leaving them with their LP set up trashed and a new unit in the tank.

 

Thanks guys.

 

Lets talk about the in-tank lift pump and speculate why it might be a good setup.

The engine mounted and fuel filter mounted lift pumps from 1998.5-2004 models had failures due to too much heat, engine vibration, electric fuel pumps like to push fuel rather than pull fuel, I cann't remember the rest right now but I'll eventually think of them.

It's a well known fact that electric fuel pumps like to push fuel instead of pull fuel. The 98.5-04 models had to pull fuel from as far away as 10 feet and then push fuel another 1-3 feet and they had to do it through a prefilter mounted in the tank. Imagine how much more it took out of a pumps life to have to pull heavier viscocity fuel in cold temps. Alot to ask of a pump that pushes rather than pull. With the in-tank design they have eliminated any pulling, the pump is located in the fuel. Thats the reason gas vehicles have had relatively few problems. Keep in mind nothing mechanical is problem free.

Now lets address the heat. On the 98.5-04 trucks the pump was mounted in the engine bay were temperatures can get brutal. They were also of the brush and bushing type. Now on the 05 and newer in-tank design the pump is located in the fuel being bathed in cool fuel. You can not ask for more cooling effect.

Now the vibrations issue. The engine mounted electric lift pump used on the 98.5-2002 models were subjected to severe vibration and harmonics from the engine. were talking about an electric pump in a severe condition. The 05 and newer in-tank lift pumps are located in the fuel tank surrounded by buffered fuel from the baffles in the tank. The liquid itself absorbs outside vibrations.

You take away some of the known causes of why a lift pump fails and you should have a reliable pump.

Then there is the question of what type is this new in-tank lift pump. No one seems to have the answer to that yet, but I'am confident time will tell.

We could have a winner on our hands with this new in-tank pump and all everyone wants to do is spread paranoia. Then again if it isn't there are plenty of option to turn to when our warranty expires.

This post is for stock trucks, not high Hp trucks, in high hp applications they know if your going to play you better be willing to pay.

Hope this helps anyone who has concerns about the in-tank lift pump.

 

I have no agenda to attack you or anyone else. Just trying to open some eyes. I would like you to point out to me where I called you any of those. I did say you were misleading in some of your posts. In fact I more than once stated you had a very good idea.

 

Since we are talking about warranties and lift pumps, I have a question.

Now that the lift pump is in the tank, does it fall under the 3/36 warranty or the 5/100 warranty?
