Fass Fuel Problems

[Justinb]

Hello all,

Just curious if anyone is unhappy with their FASS Fuel system in their 12 valve? I recently installed one and i have had nothing but problems. Had to replace half of the fitting and replace O rings on the pump it self because of leaks. My charging system just took a ****. Truck wouldn't idle anymore because obviously the lift pump want getting enough current. Don't know if the lift pump is the cause or just a coincidence.

I feel like I can't even drive to the grocery store without something happening. Thinking about converting to an aftermarket mechanical lift pump called the Predator by Power Driven Diesel. Any thoughts?

Thanks

Just and update. Just called Fass Fuel to ask some questions and they basically belittled me. Just a word to you all out there. NEVER buy a Fass product. Way to expensive and not worth the headaches.

Just my opinion being an electrician for over 40 years. If you can do it mechanically do it. Usually more dependable.

I agree with DavidC. Back in 02 or so I got a Walbro kit and big line kit from Glacier Diesel Perf., wired it per instructions and it has performed flawlessly. One time, probably around 08, the fuel psi would just 0 for no reason. Rigged a temp psi gage to make sure it wasn't bad sender and same thing. Called GDP and they sent me a new pump, no charge for anything and they didn't want old pump. As I was installing new pump I found a loose solderless loop at the pump. I let them know and they thanked me for being honest then said "looks like you have a spare pump now". They didn't want anything...
David, how much energy would a FASS pull? Just can't see it being enough to pull charging system down to a point where a truck can't be driven. Your thoughts?

Joe,
I really do not know but I would guess no more than 5-10 amps

I took my alternator out and had it tested at a local automotive alternator and starter rebuilding shop. It was defiantly bad. Like i said before I don't know it the Fass pump was a direct cause of the electrical problem but once I got the alternator installed and new batteries my truck still won't start. I started looking around and found another fuel leak at the draw straw bulk head fitting at the fuel tank. Defiantly sucking air. I have already replaced half of the cheap brass AN fuel fittings that was shipped with the pump with Vibrant Performance fittings. Everyone of the brass fittings that Fass supplied have leaked and I have had no problems with the Vibrant fittings I have installed.

Like I said before do not buy a Fass product. I have called them numerous times and all they do is try to make me feel like I'm an idiot to try and eliminate some problem on their end. If you guys are thinking on a lift pump go with a mechanical one. If I have further problems with the Fass pump again its going in the garbage and I'll call that stupid tax as Dave Ramsey would say!

I had an issue a couple of months ago. There was a service bulletin out from fass use a different kind of sealer for the hose. The outside of the hose was cracking anyway, so I had the hose replaced with the new sealer. Problem went away.

I've had great service with FASS on three Ram Cummins trucks with combined 450K miles trouble free service and no problems with any of the hardware. I personally installed everything trouble free.

I'm not trying to start an arguement here, just trying to understand when you said they were trying to help you, that you were unhappy with the way they made you feel. How did they make you feel bad?

I spent 41 years in the communications and Information Tecchnology profession and am familiar with trouble desk procedures, I fact, I created many of them. Sometimes when calling for help, its easiest to start from the basic and work to the complex. I'm even curious how you wired a FASS to a 12V mechanical fuel pump truck, a relay off the starter and the run circuits of the truck?

Is this a new installation or if not, when did you install it.

Anyway, I'm happy to help if you still need it.

Cheers, Ron

I, also, have sold and installed many FASS systems from the DDRP to the big boys for 1K+ HP pulling trucks. Yes, on occasion there will be a problem with a pump or a motor as there will be with any mechanical device, but FASS always stood behind their stuff. I can't recall ever having an issue with any of their hardware, either.

What made you feel like you needed a FASS on your "12 valve"? What year is the truck? I can maybe see putting one on a 1st Gen but the OE mechanical pump on the '94-'98's is more than adequate for anything up to 400-450 HP.

 

[ofelas]

No need to put a FASS on any 12v under 700hp, whether first or second gen.

Large piston high volume lift pumps on the above gens will handle 500hp & 700hp respectively.

I don't give a lot on FASS life time warranty because they want you to send in the unit and wait 2 weeks for it to let them examine it.
Not even the licensed dealers are allowed to exchange an unit that is clearly defective manufactured.
I wouldn't buy again too.

They are just to expensive for me.

As expensive as it is, I dont blame them for wanting you to send in the bad unit for repair. Although it could be an issue if is your daily driver. Did the op get angry because they would not just send him a new unit ? What if your brand new car has a bad fuel pump. Do you think they will just give you a new pump ? Also, if you think the pump took out the alternator, is there not a fuse that would have protected the alternator ? (Im not a mechanic, Im just guessing)

 

[Ozymandias]

I said licenced dealer is not allowed to change it.
Your licensed RAM dealer is allowed to change the part and send the defective part afterwards to RAM, if they want to.

See the difference?

A ram dealership has an altogether relationship with fca than a fass reseller. For all intents and purposes, the dealership represents fca parts etc. The fass reseller is licensed to resell the pump, nothing more. Ram, through their representative the dealer, warranties the part and the installation so the turn key system is covered. The pump reseller warranties the install only, not the part. Fass warranties the part only, not the install. See the difference ?

 

[BigPapa]

Your licensed RAM dealer is allowed to change the part and send the defective part afterwards to RAM, if they want to.

Only if they installed it. You can't take a part off your truck, take it to them, and them hand you a new one. It has to be diagnosed and found to be bad before they will replace it. And, even then, FCA may require the failed part be sent back to them for inspection before they credit the dealer. I don't imagine any of that will happen the same day, either.

You're comparing apples and water melons.

What BigPapa said.

 

[Ozymandias]

Like one want...
For me FASS is dead and i don't recommend it anymore after my experience.
Done.

I wanted an outstanding product and was willing to pay an amazing price for it- and got a not properly working unit, a customer service that not even gave an answer to my mails, and a poor dealer that only can say "i can not help you so sorry".-- what i paid another 250$ for the worthless diagnosis that the Titanium unit only works with FASS Filters and Squeal lika pig with other premium filters.
Crap!

Ned Beatty was just misunderstood, poor fellow.

Not true. Although I like to use real fass filters, Ive used I think it was donaldson filters. Worked fine. But everyone has their own experience.
