Give Me Your Fass Questions -- Part II

[Riley5.9]

Dan, haha well i feel like an idiot for saying/asking this, especially seein that the above post is on the same problem! i just wanna kno if my situation is any different.
I have a 95/150 and its about 3 months old. When i first got it, it only got loud when i was 1/4 tank or below then it shut up when i filled er up.. Now its just that loud all the time.. Loud as in i have to talk over the whining to my passengers.. i got about 13,000k on the filters.. Any input would be awesome! thanks Dan, sorry again for the repetition

forgive me for someone might have already posted this problem, and i just havnt read it. but, i installed my fass 150/95, and for some reason at around 3/8s of a tank, my edge attitude moniter throughs out a low fuel pressure siren when i try to start the truck, and then after it starts, the pressure builds and its fine for awhile and it'll start shooting of randomly as im driving. also, when i get to around 1/4 to 1/8th of a tank, it'll start sucking air through to my engine and killing it, i dont wanna sound like im not mechanically inclined, but im thinking i need a vulcan draw straw maybe for my pickup tube may be to short or something. ne info will help, thanks.

how do you think an HPFP would feel about pumping 100-200 degree motor oil (mixed with 5% diesel)?

WELL i would pull the suciton line off and place in a bucket of fuel along with the FASS return line. See if the pump is any quieter. Restriction can cause the pump to just scream if it cant get fuel. If you are ever at a show we are at, come by and have them show you with our test stand. We have a valve on the suction side of the pump to induce air into the system.

That is where i would start.

JWAM with fuel pressure...so you must have an ISB then....ok.....we might have an issue with your factory pickup or connection at the top of the tank. I have seen cracks form in the plastic tubes inside the sending unit before that only show up under low fuel situations due to being exposed. ALSO...you might double check your Juice sending unit...we have been seeing a TON of these go south...(WELL more Quad....but pretty much any sending unit that is near a VP will do it...i would look into this.....)

UM......if you get the correct pump....i would suggest our high torque motor with the smallest gear. (Our 120 GPH pump) I would make sure you treat the oil like WVO or SVO by heating it......AND no prefilters tighter than 140um on the suction side of our pump.

There is a few guys doing this that seem to have good results.....

How often do the filters need to be cleaned/changed. And where can I find them. Thanks

FASS 150 Series:

You can get about 50,000-60,000 out of them. Just watch your fuel pressure gauge. The water separator can be flushed wtih gas and reused. UNLESS you get some really bad fuel.

FASS 95 Series:

40,000-50,000 miles. The rest is the same.

To find filters:

My FASS pump has become very noisy---sounds like it's cavitating, surging, gurgling, etc. The fuel pressure gauge is going crazy. Sometimes it's hard to start.

I have pump #6224 installed on 1/24/06 @ 117k miles. HF6601 filter and FS 1023 sep. Now have 160k.

Problems started 5/08 when truck died. (fuel filters empty) Dealer installed new injector pump, but could not explain empty filters. Truck soon became hard to start at times.

I installed a new fuel pressure gauge, draw straw, all new fuel lines.

The FASS is now getting louder and pressure started going crazy this weekend. I've parked it again. I think it's got to be the FASS pump. What else is left? No codes at this time. Can I send the FASS system back to be tested, or is it time to order a new one???

well, see this only happens after 1/2 tank. and i dont think its the juice sending unit, cause i can hear the fass not working when i turn the key around 3/8s tank, so im gonna get a draw straw and see if that fixes it, idk. thanks

Sorry for the delay......i did not get e-mail telling me there was a new post until Toyotcummins posted....

If you have not done so, contact your FASS dealer and have them call me with some options....Ill update it to current standards if you can send it in.

Ok....might try pulling fuel from a bucket and see if that helps any first......

I need some help guys, my fuel pressure on my Edge moniter has been reading 0 for a while and I thought it was a bad sensor. I called Edge and they sent me a new one. Problem is it still reads 0psi. Called Edge again, guy on the line gave me a few things to do and determined that it was not the Edge and imformed me that my fuel pressure was indeed 0psi. I thought that my truck wouldn't be able to run lilke that? Anyway, I am going to put a machanical gauge on it and see what it reads as soon as I get home. My question is, What could be causing this? The guy at Edge said that my FASS filters may be clogged? He said that my truck was starving for fuel, but I doesnt seem to be still runs strong, only difference is my EGTs and engine temp have been a little hotter than normal. Any other ideas?

thanks,

First off....quit driving the thing until you figure out what is going on! Unless you have an idle $1200.00 just sitting around.

You need a mechanical gauge to double check that setup.

Do you have the FASS (Unit with 2 filters) or HPFP (Just the pump)? IF you have the FASS you can open the fuel door and listen for return fuel. The only way you would have fuel returning is if you had pressure at the injection pump. Quick easy test for pressure.

Let me know what you find...

Now that I think about it, I have had some trouble with the plug on the FASS. A while back my truck died several times there and turned out that the plug where the FASS got power was loose or had a bad connection. I went out to do the "bucket test" and before I could get to it I noticed that I could not hear the FASS running as I normally do. I wont even pump those few seconds went I bump the ignition, like its not getting any power. But the truck will still start and run normally. Is it possible to replace that plug, as I am pretty sure this is what is causing my problem. Hopefully this will be a cheap fix now that my VP is probably toast, due to me being studid and just assuming it was just a wrong reading all this time.
