[Rob Thomas]

You can add my name to the list of lift pumps with "issues", mines gettin' replaced on thursday or friday,whenever they get their next pallet of lift pumps in. :-laf I guess I can't complain to much, I got 53,000 out of it. Yeehaw.

I'm not an attorney - but surely we have one here or could get one. Of all the subjects that appears to be a design defect, this lift pump is one. I suggest we put some $$$$ and get some legal advice. This is not a convience - but a Safety Issue that must be addressed and corrected. Couldn't we make the case that loosing acceleration cabn lead one into a serious accident.

Re: The gauge....

Can anyone suggest a test gauge (as opposed to a permanent one) that won't break that bank, so to speak? Now I'm getting a little paranoid... ... ...

Contact Briar Hopper. You can find his posts and profile/contact info earlier in this thread. You could buy the parts and make up your own a little cheaper, but if your time is worth anything to you and you drive across town twice looking for the parts, you won't be saving anything. I ordered via e-mail Friday; he shipped Priority Mail and I checked pressure on Tuesday, but only because I didn't have time on Monday when the gauge arrived. Ask Briar to be sure you have the right fittings - I'm not sure which year the Schrader valves became standard; I just know they are on 2000 and 2001. It's very easy to check with this set up.

Checked pressure on lift pump.



10psi idle

7 psi at 70 mph

3 psi WOT



Dealer changed lift pump this morning and have not check the new pressures yet. No hassle out of the dealer. Only 15,644 miles on the 2001. They covered the cost.

Just got back from the dealer. As posted earlier mine was "DEAD" "0"PSI. Took them 45 minutes to install new AA suffix lift pump. Covered under warranty, just sign and go. PSI's after new pump installed, using Briars guage 13psi idle, 10psi cruise, 6psi WOT. I will continue to use Briars FP guage to keep an eye on my pump. Based on the change in the power of my truck, I can tell a difference with the new lift pump. I got to say that I have a great dealer Aurora Dodge in Aurora Missouri.

Very interesting thread. Most of the trucks that I have seen listed are 01. 5s. Has anyone had pump problems on 02s?



I am considering buying an 02. First stop alarm shop, 2nd stop fuel pressure gauge install?

 

[Murle]

Got truck back from dealer. Pump is now putting out...



15 psi idle

13 psi WOT.

Steve:



I agree with PITBULL. I think your poll should include the choice of lift pump failures with fueling mods. Would give a much clearer picture of problems due to fueling mods if that is the case, which would also help some of us to make the final decesion to modify or not.

just had the truck at the dealer.



key on 11. 5psi

idle 11psi

wot 9psi



it is only time till i have to replace the lift pump right.

 

[Steve St.Laurent]

The max number of answers allowable in a poll is 10 - there wasn't any more room to add other options unforetunately. The biggest thing I was trying to seperate out with this poll over the previous one is whether people had checked their pressures or were just assuming it was still good because the truck was running. Your welcome to start a new poll if you'd like.

WOT

there are conflicting methods for measuring the pressure at WFO (WOT). mine measures 4-5 if i'm moving, and with all the nerve i've got to open it up in neutral, only drops to about 9.

 

[Steve St.Laurent]

The WOT test is to be done under load according to STAR - not in neutral.

 

[redneckdr]

WOT pressure

thanx, steve. it makes more sense that way. that is the "real world" the VP44 sees. i'm just watching mine for now. hasn't change any since i installed my gauges about 9K miles ago???

 

[stephen bolger]

STEVE THEY DID THE TEST IN NEUTRAL SHOULD I HAVE THEM REDO THE TEST UNDERLOAD.

 

[HOSS]

Steve,

I voted yesterday (no problems at 50k-100k)and had to stop at the stealer on the way home and guess what no lift pump! they are replacing it tomorrow.

 

[Big K]

It's not over yet... .

Checked my fuel pressure with the test gauge Saturday. I'm all stock, and don't need to worry too much, right?? NOT!

Idle 6-7

Cruise 0

WOT suckin' vacuum

Appointment @ the dealer on Thurs.

Gauges on the way!

 

[Wheaties]

Just got gauges. Switch me from the 'Don't know -- assume it's good' category, to the 'Know it's okay' category.



Idle: 15 Cruise 10-12 WOT: 6-8



Just hope it stays that way!

Could this be the cause.......

... ... . tonite I ran into a person who works for a regulatory agency. She just got done attending a class where they had a session on various scams involving fuels, in particular diesel.



Apparently the bean counters were relating to the class just how widespread in many areas the practice is of "watering" down diesel by some of the distributors... ... crooks looking to make big profit margins will water diesel with just about any and everything. I think a number of us knew this all along... ... ... however, the bean counters made a point to show, via statistical analysis, that in some areas, what is being sold to the retailers by a distributer far outweighs what the distributor bought in the first place.



I guess the gist of the class was to show the regulatory outfits that they are getting ripped off big time on taxes... ... ... and that this problem has grown exponentially to the point where its a big issue.



Well, if some of these guys are cutting our fuel with stuff like water, jet fuel (that was repeatedly mentioned, and can't figure out what the advantage would be there), and other stuff, wouldn't that tube our pumps pretty much on the spot??? I suppose it would have to be really widespread to do that to so many pumps in so many places... ... ..... but I guess my question is if watered down diesel would ruin a lift pump?? Certainly the main pump, right???
