Engine/Transmission (1998.5 - 2002) Who has the most miles on their FASS fuel pump??

[GIT-R-DONE]

HMMmmm - 15 users, 5 failures - sounds like the stock LP's might not be so bad after all - a 33 1/3 failure rate sure isn't anything to brag about, especially in an expensive aftermarket setup supposedly designed to *eliminate* the problems common to the stock Carter lift pumps...

I guess thats a fair assumption, 1/3 of all FASS users musta broke because of this thread. I supposed they only sold 15 of them.....

 

[bpenrod]

Maybe this should have been set up as a poll if we are going to interpret numbers. I have 40,000+ miles on mine without a glitch.

 

[JimKing]

I agree. Folks that have had a problem want to tell the world what a POS the pump is, those with no trouble have other things to do.

Almost 2 years on the FASS and no problems. Not sure of the miles,but quite a few.

 

[cpeters]

35k on mine and the only problem I had was bad ground causing the brushes to wear out have gauge so it was no big deal, other than that no problems/very happy. I run it at 15psi.

Don't be so qwik on your ASSumptions... ... ... ... ... .....

You don't know if there is any underlining problem with the trucks/members and the installations of each individual pump. Let's hear on some of the conditions that are happening and maybe we can help figure out what caused the demise in the first place... ... ... ... ... ... ... ... ...

OR, could it be that those who manage to own a problem-free one just figures those who DO have problems must be 5-thumbed idiots?





Perhaps yet another "ASSumption" that prefers to ignore reality?



Face it, regardless of HOW FASS fans might rationalize, given the relatively FEW users on a board like this, this thread reveals FAR too high a failure rate - and yeah, those SAME fans quite likely used the SAME sort of limited-user info to brand the stock LP's a "a piece of failure-prone JUNK" prior to buying the FASS that was SUPPOSED to eliminate all that...

Well it seems to me that when your putting on a new pump and it makes noise- do you keep it and pray it lasts-or send it back for another- bad grounds causing premature brush wear- how many were run with clogged filters stressing that pump even further... . ect. ect. ect.

All I'm saying is BEFORE any ASSumptions are to be made- lets hear the whole shebang as to why it went out in the first place... ... ... .....

I didn't say that you did!! All I'm saying what are the conditions to cause the problems... ... .....

 

[GIT-R-DONE]

Gary, do you own or have owned a FASS system ?

 

[Gary - K7GLD]

"bad grounds causing premature brush wear- how many were run with clogged filters stressing that pump even further... . ect. ect. ect"





UMMmm - wanna run that "ASSumptions" bit past us again? Seems to be a fair number offered or suggested in the above quote - as well as a tendency to stubbornly RESIST the very real possibility that JUST MAYBE, an unusually high number simply failed due to bad design, quality control or poor internal tolerances...



NO, I not gonna stick around and debate this endlessly - the "evidence" seems clear enough to not hafta beat it to death...

 

[RacinDuallie]

No gary it's been my experience that wound electrical motors absolutely need good grounds for long life or the fields run hot which inturn make the armature run hot which then causes premature brush wear... ... ... ... ... ... .

And to keep a pump that doesn't sound right ... ... ... ... ... ... ... ... ... ... ... ... ... ...

All I am saying is lets hear the reasons someone says they're junk and then form your own opinions from what was explained... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... ... .

And so far I have not seen any real evidence

Have you ever even owned one to make a justified comment anyhow?

 

[Gary - K7GLD]

"Have you ever even owned one to make a justified comment anyhow?"



JEEZE, I get SO sick and tired of that "desperation" response - NO, I *haven't" owned one - NOR does that fact PREVENT me from an educated *opinion* based upon presented facts of others who DO have them...



I haven't tasted dog poop either - and don't HAVE to to pretty well figure I wouldn't like it - never climbed to the top of Everest or treked to the North pole - but I can still pretty figure that neither are MY cup of tea!



I can't play the piano, either - but I can certainly recognize a sour note when I hear one!



And those who have no BETTER argument than the fact that "you have to actually HAVE one, before you're entitled to express an opinion" are standing on a VERY slippery surface, since chances are, THEY TOO probably have quite a few opinions on stuff based purely upon evidence and the reports of those who HAVE had direct experience, and passed that experience on to others to help guide their choices.



Isn't that ONE of the REASONS for this forum?

 

[pgleavitt]

47,000 miles on mine and no problems. I did install the upgraded power relay setup at 22,000 miles and changed the bypass spring and ran 20psi for 3 months. Went back to the original spring and it runs at 14psi. Very happy customer.

 

[RacinDuallie]

Gary-
While you make your assumptions on other peoples negligent installs and/or maintenence that probally caused the demise of the pump in the first place- I personally know of atleast 18 FASS installs that I have recommended and helped with the installations of some of these installations- and helped troubleshoot some incorrect installations- and everyone is very happy with their purchase and experience with a FASS.....

I don't work for a shop neither, nor do I have any benifits coming to me from the makers of FASS.

 

[tractorface]

RD has a good point about installations etc. I also think, as with many similar products, the on going improvements being made have made the product much more reliable. No One can do any real failure analysis based on comments in a thread on the TDR so Gary's opinion is just that his opinion. Never having used a FASS means he has less "data" to work from than you and I. No sense in arguing with the guy, he is allowed an opinion. I am comfortable that the FASS is a permenant solution, just because they did not hit a HR out of the gate like the RASP folks seemed to that does not mean the product can't get the job done.



To all the guys with a FASS, take RD's comments seriously, the wiring needs to be correct. This means install 14 gauge wire use a relay with the coil wired to the old pump's harness and make sure the ground from the FASS motor is terminated to the battery ground. A good place is under the same srew that the driver's side battery is grounded to the front fender. I would also submit that too much restriction on the supply side of the pump will shorten it's life. I think this may be a big reason the stock pumps fail (maybe aftermarket pumps are not needed at all) I would love to see data collected from a lot of trucks showing the restriction on the supply to the pumps (from the OEM fuel bucket) I have seen big AC powered pumps ruined by too much retriction (collapsed hose) on the supply side. Restriction = wear which is why running excess PSI is probably not a good idea for long term relability either.

 

[darkhorse]

I own a FASS II HP fuel pump that I have yet to install as my "POS" stock lift pump still maintains 10 psi at cruise after 60 k miles. I will say that the FASS looks & feels like a quality product. I was alarmed at first by reports of failures, but threads like this one have pointed out some of the potential problems & what to do about them. Should my original pump fail, I will install my FASS with confidence.

 

[Casey Ray]

After going through three oem pumps on my truck all in under 14k miles, I upgraded to the FASS II this past April. Don't have as many miles on it as some of these guys, but my experience says it cannot be as unreliable as the design Dodge came up with. If by chance I have a problem with it, I'll get it rebuilt, I have spare brushes, just in case I need them. Install was easy enough and the placement back by the tank is great.

Pull this thread up again in a year and we'll see where everyone is with these pumps.



Enjoy your truck,



Casey

 

[DEngelhardt]

Read your post. Could you give me the part # and where you got the Hobbs pressure switch. Sounds like a great idea. Did you put in a relay powered by the old harness to control the FASS.



Thanks.

bad bearing

8-9000 on a filter I run the 2 micron Napa and changed it after 20,000 with no benefit. Going by sound and post filter pressure gauge but think I am ok. It would be best to look at the pre and post filter pressure drop but I have had no problems yet. What makes you change them. Just curious.



Oh Yeah I had a failure at 10,000. Bad bearing Like that since day one noise just kept getting louder till she failed. Replaced under warranty and blew a fuse 20,000 miles later. Know have about 26,000 on it with good results. I have upgraded the Wiring harness and built a custom fuel module with a 1/2" stand pipe. I think the bugs are worked out now and have good deal of confidence in it now. I would say that it is very hard to beat the RASP but FASS can be made to work well if you take a few extra steps. I also run a Hobbs pressure switch wired to the old Water in fuel light to alert me if pressure drops below 10psi. My personel opinion is that many run too High a pressure with the FASS. I fell better about running 12-14psi rather than 19-22 like some do. Lower pressure should be easier on everything. JMO

what happens when bearing fails does it knock or tick on the way out
