I dont follow how this system works...... Any help to unconfuse me would be appreciated.

The FASS has a very large gear pump, pulls the fuel through a strainer/water seperator, than pumps through a larger 10 micron filter. It has a regulator with a ball about 3/4 inch with a spring to regulate it and this can be tweaked to set the pressure. It also has an air seperator that I have no idea how works. The FASS kit comes with hose and fittings that start with the quick disconnect at the tank and ends with the fitting on the VP pump. It uses push on no clamp rubber lines. They can also supply a tap for the FP gage that can be installed where every you want.

 

To expand on what Haulin said.

The stock "lift pump" or "pusher pump" has to suck the fuel from way back in the tank.
It was designed to be used closer to the tank, not 6 feet away.

The FASS is mounted right by the tank, so it's actually pushing the fuel up to the VP44.
Also, its a bigger pump, better filtration system.

OHHHH I get it now thanks yall.

 

Do you use the FASS in conjunction with your stock lift pump, or toss the sucker?

 

Toss the entire fuel system, filter, lift pump, lines and all.

 

Haulin,

I am real interested in getting a F.A.S.S. system.....the factory setup bugs the mess out of me. Can you let us know how this system performs once you have some miles on it ???

Thanks.

 

Haulin,

Ditto on what THE DR wants (prescribes ).

One other question, do the exsisting wires that work the transfer pump work on the FASS system? Or would you just wire in to an accessory/key on HOT wire?

 

The one I read about plugs in where the stock lift pump did.
I like the idea of this system and will go to it when this lift pump goes out.
My question is how do you bleed the system when you install
new filters, does it do automatically?

 

I've got over 30,000 on mine. Changed the filter once, it did not need it. How I bled it was to bring it up til the rubber just touched with a little pressure, turned on the key, tightened it while it was running., that way it was with a dry filter. Did that at a truck stop pump island. Careful doing that stuff, a lot of volume. I plan on installing a valve to bleed it with a small orfice. Changing the filter is a two minute job. Don't know how long they last yet, the fleetguard is supposed to last up to 90,000 miles. I am well satisfied with the unit.

 

Will be watching for replies on the F.A.S.S system.

Also I have a question about the OEM pump. If a person installs a filter close to the fuel tank and move the OEM LP close to the filter then continue normally though the system to the injection pump except remove the element from the OEM filter housing. What could be expected of such an installation? This way you will have filtered fuel going through the LP.

 

I hope this system proves itself worthy. I'm tired of messing around with fuel pumps and stuff like that.

 

6cylinders,
Depending on where you get the FASS system it may come with the plumbing and wiring harness which will allow it to be plugged into the existing lift pump connector. Smokindiesel.com sells them this way. I also believe that they have done it right, in that they do not use direct voltage from the lift pump connector, it just runs a relay, which is better because the lift pump connector draws directly off of the computer. When I set up my Holley Blue I ran it into a relay and connected the lift pump connector to what powers the relay. That way I don't draw too much current off of the computer.

I am starting to think that the FASS is the "cure" we have all been looking for. I guess only time will tell.

 

That's what we thought about the PE4200 pump as well. Until they got some years and some miles on them and they started failing.
