How do I know if the FASS is working and customer service support

I just picked up my Volvo after having the FASS put on by a shop that I go to all the time to get all my work done at after having my truck there in the bay working on it for 4 days just to put on this FASS. What a nightmare this has been. Today is Friday and when I showed up at the shop around 3 pm unexpected to check what was going on there was only one unhappy tech in this shop and he was working on my truck with this FASS install. I talked to the tech about what has been the problem and everything has resulted to working with the tech support at FASS and the directions they have given in there install manual not being up to date or incompetent techs to talk to at FASS. I am blown away at this point I am at one of the best shops that I know of and from what I have read the best product ever made for my truck and there is this big of a problem. So I call FASS for some help to find out where is the missing link I wait about 20 min to talk to the only tech that is the best in class 8 trucks and he tells me that he told my shop to call another shop that has nothing to do with FASS in Canada that puts the FASS on all the time. I said, so you cant help the shop. In so many words it was explained that we just make the product we don't install it. Then what is the tech support for? I ask the tech about the call to Canada and that shop said to not to even go off of the directions FASS gives them. Remember this is a shop that FASS says to call. At this point my hands are shaking I am getting red in the face and I want my truck the people in the shop is watching me give the people at FASS !@#$ and I tell the shop manger that I want my truck done before anyone goes home. Long story short, what was going to take until Monday to get the truck I got back in about an hour after loosing my cool. Now I am worried was it done correct. Is there any one that can help me?

Answer this question I have this problem too

Is this a good question?

Well, I installed the one I have on my Volvo D12, this FASS unit was on my 1 ton dodge truck, I had that Cummings bumped up 150 hp.

It took me less than two hours to run the new/separate return line to the fuel tanks. I then removed the Davco filter that was mounted on the drivers side between the front tire and the engine. The Davco filter was mounted on a good strong bracket so I used the mount plates that came with the FASS and mounted it there. All you have to do is take the in and out fuel lines off the Davco and put them on the FASS. then run a separate return. I had two 3/8 plugs near each filler cap on each tank, I just removed them and put a fitting there.

Here is where I had problems, both with the manual that I downloaded from FASS that applied to my engine, and with making sense of the instructions.

FASS could not tell me how to decipher the instructions. I went online and downloaded the Volvo service bulletin that gave me a really good view of the fuel system.

I then faxed the print to FASS and asked them to tell me where to tap into the return off the head.....this is the benefit of the FASS by doing this properly....this returns the hot fuel from the head back to the tanks.

I will not say it saves fuel, gives more power, or the engine runs smoother....but I think it does.

What I will say is I know that I am getting more fuel delivered to the gear pump under pressure instead of under suction. I'm positive I'm getting cleaner fuel, no water and no air in the fuel...and no hot fuel going back into the fuel loop.

On this engine, the ECM injector control banks in the ECM are cooled by the fuel that runs through the ECM. This should give my ECM a little heat relief.

If anyone has had fuel delivery problems after installing the FASS then it probably had a bad install....if done right I think it is a benefit.

Hey DLP, I had the davco on mine as well. The steps that need to be done sounds simple. The shop that I took it to are big gear heads they will work on anything. You would think they would not have had any problem. I think most of the problem they had was dealing with FASS and the directions they gave.

You should hear the FASS running. I personally don't care for the product it never did anything for my Detroit Series 60 other than make me run out of fuel. I know the Detroit shop here in town where I live has got a nice little collection of the FASS systems that they have been taken off trucks when the drivers comes in complaining of fuel problems and they trace the problem back to the FASS.

Chad, the system is simple. one line from fuel tank goes to the pump to supply fuel. then a second line sends the fuel up to the engine fuel pump and a third line is a return which needs to be split so the fuel returns to both tanks.

Your, i'm curious how the fass made you run out of fuel?

I guess the one on my truck is not working because I don't hear nothing. I asked FASS how do I know if it is working. They said is the truck running I said yes they said it should be working. Jerzy I read allot of your post because I like the advice you give but for you to say that the FASS is simple is wrong. If it was simple then they should be able to make a manual that any one could use to put on. If it was simple if would not take shops 8 hours to put it on. Maybe its because my truck is a Volvo. Next Time I see FASS at a truck show or hear them on the radio I will ask them how simple it is then I will give them my story

thanks, you almost make me sound like i know what i'm talking about :) the system is simple but it is quite time consuming to install. i ordered mine from pittsburgh power and it came with instructions...but without the installation kit which cost almost as much as the system. when Your said you'd hear it running he meant it because the pump is loud. i wonder if your shop wired it wrong - mine comes on with key "on".

Just got back from checking out the truck and yes I hear it now when I turn on the key and some of the lines get warm after it is running along with the motor. Yes I like reading your post. I guess the FASS is working but is it working correctly and was it hooked up correctly. I am still floored that the fact that the people at FASS cant help with this. Its like they have out soured there call center to people that speak English.

Jerzy the first time was when it was new it wouldn't pump enough fuel to keep the engine running in a hard pull so I to take it off and send it back to the factory to have the pressure spring changed. Fass was good about fixing it. Matter a fact they even sent 2 extra pressure springs back with the unit that had different pressure settings in case the one they put in wasn't enough.

glad that they took care of you because i've read some less than positive reviews about their customer service. i've heard though that even if the pump fails the engine fuel pump should have no problems sucking fuel through the fass on it's own.

More then any product Kevin talks about .... The FASS you hear the most problems with. PDI does our custom work. They used to sell and install the FASS , they don't anymore. I asked them if I needed a FASS and they said no .... We did not go any further I should ask them to tell me a little more. PP still believes in FASS maybe you should try calling them. I know Eldon in Nebraska is a master of the fuel system I'm sure he could help.

The father of the FASS is the Airdog. If you learn the history of the Airdog and how it was bought and sold over and over it makes you think the FASS is going to turn out the same way. Who is PDI?

I just installed a FASS on my glider... I can't believe anyone could ever have trouble with the install! It's an EXTREMELY simple setup. I had it done in about an hour.

The only minor problem I ran across was that I forgot to spray WD-40 into the pump before I mounted it (as the instructions told me to). Being a new glider, the entire fuel system was dry, and the pump wouldn't prime on its own with dry gears. I got past this by cracking the return fitting at the engine-mounted fuel filter to let air escape, then gently pressurized the fuel tank with a blow gun through the tank vent. It took about 5 seconds for the pump to catch prime and has worked flawlessly since.

I'd say the shop who did your "install" isn't as good as you think they are.

I agree with Corey, your shop sucks!!,, My mechanic installed the FASS on my 3406B in short order and then he removed it and reinstalled it on my DDEC IV, I don't have any fuel mileage figures or performance statements but it works by eliminating the air, I like the FASS if it only supplys the main fuel pump with pressured fuel instead of vacuum, ALSO, I agree with FASS customer support "SUCKS""""""""""

On my Volvo the fuel system is outrageously complicated until you take it apart. I did this because the hand pump failed and started leaking. I had to change out the filter bracket where the filters screw onto the engine.

You learn a lot when you take something apart and remember how to put it back together and it works. The print I downloaded and sent to FASS helped, but I still needed FASS to step up and tell me I was correct in what I thought I should do.

If you are fortunate and can start with a blank canvas like a glider, you have the luxury of no grease, no raw fuel hitting you in the face, no road film that GoJo won't take off....and all the room you need as you are putting new and clean things together.

And yes, the engine pump will pull through the FASS, I had a broken connector, I'm not really sure how long it ran this way, because I listen for the pump every time I turn the key on, it is right in front of the steering wheel under the hood.

The FASS system should have nothing to do with the Volvo fuel system, it simply hooks up at the supply line from the tanks, the outlet goes to the factory fuel pump and the FASS return line goes to a splitter that returns like amounts of fuel to each tank, if your tanks only have 1 vent hole in each tank, you can stack the vents with a "t" and both returns can go in the same hole. Hope this helps!
