FASS Trouble

[jabird]

I know this is going to sound off the wall, but, driving down the road the other day I looked over and watched my fuel pressure drop to zero. Now I'm sure everyone is going to find this hard to belive, but I really felt my FASS was suspect here. I know these units are FOOL proof and go hundreds of thousands of miles without any matinence issues. Anyway, after a few choice words I reached in my tool box and pulled out my "FASS repair kit", crawled under the truck, and wacked the pump motor with a hammer. I just wanted to say thanks for all the useful post's I have read on TDR and was prepared with the proper tools to "fix" my $500 fuel pump. One last thing... ... ... DAN, dont you dare jump on this post and tell me how you"ll help me with this issue. I already know that I can get the newer motor style with the sealed brushes installed on my pump for a couple of hundred bucks, plus shipping. I would also assume that this trouble is somehow my fault for not having reran a ground wire to my pump... ... oh wait I did that. Or maybe i should have replaced my brushes... ... . oh wait I've done that also. Or maybe I should have put alittle silicone over the brush caps so water couldn't get in... . oh wait covered that one also. Well... ... ... . if someone could jump in here and let me know WHAT I DID WRONG to my pump to have it fail again in 40,000 highway miles of its life, please feel free. Thanks for the rant space... . I feel alittle better :{ :{ :{ :{ :{ :{

40,000. That's pretty impressive. Mine quit at 22k. The Fass has not been missed one little bit. I installed a stock 12 valve lift pump about a year and a half ago. After a while you just forget it is there and quit checking the pressure.

Sorry to inform you but it's really your own fault that your Fass craped out. You seem to have missed the larger ball replacement on the fuel pressure regulator upgrade. According to Brad you would have been sent this part for free if you would have sent in your warrrenty card. Maybe they missed you too cause I still don't really know what the ball upgrade is all about as I didn't get one either.

 

[jabird]

See... ... ... ... ... ... ..... I knew it was my fault!!!!!!! I did send in that card though

 

[pgleavitt]

I sent mine in too but I guess it should have been registered mail. When I did contact them they did say they would sell me the replacement parts.

Did the whack fix it? It does sound like another hung brush unfortunately... maybe a faulty relay?



I have 40k+ on the newer motor with no issues to date... I was like you though... I bough extra pieces for mine (ball, springs, and brushes) just because of what I had read on here...



Good luck, sounds like you pretty much know the problem...

Another happy FASS customer I see. . . sorry couldn't resist.

 

[CBrahs]

Makes me really want to run out and spend that kind of money for problems! Might have to scratch that one off my wish list.

I got on them at the SEMA show to use brushless motors so they are a little more bullet proof.

The motors we are currently using are doing very well for us. BUT don’t think that option has not been looked into.

Dan... ... ... . I even asked you nice to stay out of this post but you didnt. I wrote a reply to this about 100 times, none of them were suited for posting here. You remind me of some political pundant trying to put your "spin" on an issue. The company you work for is not going to give me a sealed pump, or an updated wireing harness. If i want those things I am going to be paying ful retail. Thats what would make the difference between a pump, and a GREAT PUMP. Maybe your newer pumps and models are alot better. But some of the older models have issues and you know it. Brad should be standing behind the older pumps more to make it right, not telling you it's another $300 for a pump motor.

What really gets me P. O. is that when I bought mine they advertised that the fass was a proven design that on O. T. R. trucks have seen 500,000-600,000K trouble free miles and was the ultimate fix for DC inferior design fueling system. Not only that but it also removed air from the fuel for better performance. Alot of other members called B. S. on the performance advantage until proven on a dyno and that claim went away. Still others said lets see a track record on Dodge before they would buy one. Well the results are in and not looking too good. I would have preferred not to have been part of the R&D for what was advertised as a proven product.

 

[RonA]

They had problems from the beginning. There was never a performance advantage. There is no way that they had gone 500k-600k trouble free miles. All those claims were made 4 years ago when I bought mine. To their credit, they were easy to get in touch with on the phone then. There were a number of little fixes back then. The mark of a new product, not a tried and tested product. I think the whole air dog/Fass thing was a show to make it look like it was so good that people were fighting over the rights to the design. I heard the government was buying the airdog. That figures. They've been wasting my money for years.

 

[jabird]

Thats exactly what I was trying to say... ... ... ... only I couldnt seem to type it out as nicely!!!!!!!!

Jeff, I am running some Duramax pumps from Kennedy Diesel. I just had a bad feeling about FASS.

 

[DWeiler]

I ran a older fass/filter for a couple of years and then it started to make some noise after pulling my traveltrailer one day,changed filters and still noisy,i took it back to the place i bought it from for an Airdog. The Airdog has been trouble free ever since,but i did get a few pressure fluctuations in the real cold wheather with the stock filter(5micron),now going to try a Fleetguard 10 micron and see how that does. The airdog is real quiet loaded or not right behind the cab---the Fass was installed where the spare tire used to be and i could here it inside the cab running over my B1-2. Fass has had a few changes over the years,but it seems to me that the Airdog came out to compete with fass and has done well with fewer problems. NOTE-:NO FASS/AIRDOG WAR INTENDED,ONLY MY MEASLY 2-CENTS. LATER DW

for the upgraded cost of the fass you could almost buy a glacier diesel walbro system and be running aagin with no problems. I got 6 fass pumps on the floor that need to be fixed. Gets old fast when they tell you to fix it yourself, ... ah my time is cheap there's isn't i guess. They convinced me to tell customers that the pump was warrentied, ..... ya by me, lol.

 

[LowFly]

Dan... ... ... . I even asked you nice to stay out of this post but you didnt.

And i asked for your SN number to see if i could help you out anyway i could. BUT i guess i can't help someone that doesn't want to be helped... ... ..... you will not see me again on this post... . sorry to "Intrude". I don't want to waste your time and mine... .....
