Hey everyone,

I installed my Fass 200 today on my 06 and a couple of things have happened.

1st, it is really noisy to the point you can easily hear it over the motor---a pretty much constant whine with surging and pitch changing all the time and sometimes sounds almost like a grinding noise??

2nd, the 30 amp fuse blows occasionally, I can let her sit and idle and its fine, drive it normal and its fine, but if I really pour the coals to her the fuse will blow.

How noisy is normal?? Hard one to tell unless I had one to compare it to? I can tell you this its, embarrassing sitting at an intersection. I've had in line pumps before on my hot rods so I'm use to some noise but this is ridiculous.

Why would it blow a fuse when its just a constant run pump? That doesn't make sense to me.

A couple of notes, one of my fittings was missing so I had to get my own brass (coming out of the tank) I used 3/8 fittings though.

Also, the placement of my suction pipe in the tank had to be different than in the instructions as my overflow is in the spot where they wanted it---so I just moved it to a different spot and had to get a longer pipe to reach a bit further, still used same size pipe.
One other thing, my fuel gauge doesn't work now-----I'm sure something I did on that one? (Suppose to cut a black outer wire at harness, I did do that)
I spent about 6 hours on the install making sure everything was perfect---I even built special brackets to hide the fass a bit better (that thing is freak'n huge)

Yes, I did read through the Fass trouble shooting guide-----I have not done the 5 gal bucket test yet-----kind of tough to want to start trouble shooting on a brand new product-----I haven't even sent in the warranty card yet.

I'm not going to bash the product as maybe its something I did or didn't do we will see.

Thanks to all and sorry for the looooong post.

sell it and go to glacier diesel power but then again that not what you wanted to hear. anyway the GDP set up is wicked

 

Depending on how the pump is mounted could affect the noise level. I had a Carter electric pump mounted with a steel bracket to the frame and the noise was horrendous. I then mounted with three cylindrical urethane isolation mounts and it quieted down some but still unacceptable. I finally purchased the kit from Glacier Diesel Power, very quiet.

As for the blowning the fuse the shaft of the motor to the pump may not aligned properly and because of this the pump draws more current than it should; or you may have a high resistance connection either at the ground or power supply for the pump. Where are you tapping into your 12 volt power? If it is from the connection for the in tank fuel pump that could be the problem and also the problem for your fuel gauge. Anyway goos luck with your project.

Anybody that thinks they need a 200gph pump must be putting major power to the ground. I never heard anybody running outta of fuel with the FASS 150 (which I have) or a GDP. If I would do it again I would have bought a GDP kit. Just some of my 2 cents

 

My FASS II was noisy for awhile, but quitened down. I can still hear it on startup and while standing right beside it. The noise doesn't bother me, in fact, I kinda like it.

As far as the fuse, I'd check all the connections, especially the grounds.

I can't speak of the Walbro as I've never delt with one. They are still fairly new in the diesel field and I have seen a few posts where they had some problems. Just like the FASS, the problems could have very well been caused by installation errors.

As for my FASS, I consider it money well spent. My first lp lasted over 100K, but the second only lasted about 30K. Since I installed it, fp is not an issue.

 

My connections are good. The ground is at the battery and the power is at the hot side of the fuse for the cig lighter.

I think the gauge isue might just be the connector, I read the instructions again and feel like I cut the right wire back at the connector?

As far as mounting goes, its solid and tucked up as high as she will go, i didn't want the filters sticking out to much.

Install was not some hack job, I take my time as I am very particular about my stuff. The only thing I'm wondering about is the 3/8 fitting I had to supply and the fact I had to mount my pick up tube in a different spot----I really dont think either one of those things would cause this issue. Everything is routed nice, zip tied, no kinks or severe angles, protected hoses where necessary etc.

I sure appreciate the good info here, you guys are great.

I may try the glacier system just to see-----man I spent a lot of time on this install though

 

I am thinking about buying a Fass system and wanted to find out if you had resolved your problem?

 

No, not yet.

I have dbl checked my electrical and fuel lines and feel that its all been done correctly----so now I'm wondering about my gauge issue, maybe when i put the assembly back in the tank I did something to it? I was pretty gentle with everything? I'm assuming the black wire they have you cut is just a ground for the in tank pump?

I did a lot of searching over the weekend and ran across some info on a site that said that the Fass 200 was for 800+ hp applications----ahhh well I'm definately not in that category so I'm wondering if the pump is just beating itself to death, meaning no place for fuel to go? I may have been over sold?
Sounds like the Fass 150 would have been the correct choice, however, I do have twins coming and a heavily modified cp3 and big injectors too.

Oh well, its only time and money right

Diesel Dan any advise?

 

you could try some sound insulation between the frame and the FASS bracket to try to quiet it down.

maybe the 3/8's fitting is bottle-necking the fuel down, so the pump has to work overtime? I'm not sure, just thinking out loud here

hope this helps

 

I would be willing to bet that the black wire is the ground for both the pump and the gauge, I believe it is a plastic tank so you would need a ground wire to complete the circuit for the fuel gauge also. Are you sure you were not supposed to splice into the black wire? What gauge is the black wire: 18, 16 or something else. With that big a pump an 18 gauge wire would be pretty light and is probably getting hot and dropping the voltage hence raising the current draw for the pump. Most 30 amp circuits are 12 maybe 14 gauge wire.

You are right, it is a plastic tank and the black wire that I cut is a 12-14 gauge wire. The pump (fass) grounds directly to the battery.

In the instructions it said on 06 models just to cut "the outside black wire" at the connector. I did this, but I to am wondering if the gauge incorporates its ground through this wire----

I will definately post what I find in case anyone else runs into an issue like this.

Thanks to all!!!

 

Here are some suggestions:

Do the bucket test. See if the pump quiets down. If it does, you may be sucking air from somewhere. We have seen some compression fittings fail when they look to be tight. (We just threw out about 1000 of them...all bad) Double, triple check all your suction fittings. Did you use thread sealer on your Suction tube kit? Can suck air from there if you didn’t. Any air will cause noise.

The 200 GPH is the big boy....its for high pressure/volume requirements. Like 180 GPH @ 45 PSI....where you will need to be for your modded CP3.

We have had some small issues in the past with the connectors on the FASS to harness connection. If you wish, cut the connectors and solder them solid and seal with heat shrink. This would ensure a good connection. OR contact your dealer for another harness. Fuses blowing should not be happening.

As for the fuel gauge....the 2 inner wires deal with the fuel level on the connector (Pins #: 2 and 3) The outer pins deal with the Fuel pump (Pin #1 -- Gnd ; Pin #4 -- Power)...there is a obvious difference in wire gauge. I would suggest reinspecting the sending unit in the tank for any disconnected wires. The gnd should not be common for the pump and tank level float.
