I haven't drained mine since a few months after I got the truck, I'm just worried about that one bad batch of fuel I might end up with some time.

When you drain the seperator doesn't it drain fuel as well, not just water and then stop. The few times I did drain mine it seemed like I was just draining fuel, this is why I never bothered to do it anymore.

 

Wait until you have a slug of water freeze up on ya....been there, done that (-25)

 

Got the shirt! Use the heaters and WIF sensor. Cheap insurance.

 

reading all this confirms all my original beliefs on me using my OEM filter and housing with my FASS II pump only..............heater is there and so is the WIF so why take it out?????

seriously just plumb in the OEM housing along with man......if ya get water then the WIF light will let ya know

 

That's why I had decided to put the stock cannister back on. Comin home from cali last winter across them damn mountains. All the way from Salt lake City to Cheyenne with a few short excpetions I was runnin 4wd and couldn't see more then a few feet ahead of the truck through the snow and ice blowin. Then the fun started, I hit Nebraska and there wasn't any snow but is was about -28 for temps. Through this whole thing, even with PS in the tank the fuel got thick enough that I blew the fuse in one of the lift pumps. I had to flip the switch and use the other pump till I could get someplace and change the fuse out.

 

Why run it???..Its not needed unless your constantly seeing sub zero temps and if your using a quality fuel additive there should be no gelling issue.The WIF sensor is about the most bogus part of these trucks I ever seen.I have had 4 trucks now and have yet to ever see it work or come on.

If you do want the heater why not use a 12v heater and run your return line fuel back through the heater and on to the tank.It doesn't matter where its warmed as long as its done and I have done a few like this for guys out here,both 24v and 12v trucks.

 

Only time I have seen the WIF light was when I had the sensor dis-connected and it rained. Moisture would hit that open sensor and turn it on. But I've never seen it while it's hooked up. It must take an extreme amount to ever set it off or I've been really lucky through the years, and I'm not really lucky at anything.

 

It dont take allot to set that light off. I've had mine go off probably 20 times since I got my truck. Its a pain in the *** when you get bad fuel, had a few places that always ended up getting water in there diesel tanks.

 

thats all its done for me too, when i tried draining it all i got was fuel.....seemed like a waste so i havent done it since

 

I had 20k on my first set of FASS filters and when they were changed I still had 40 psi on my gauge.When we drained the water separator from the bottom to allow for less of a mess when removed we did it into a clean paper cup.I only had a few drops of water and the rest was fuel.I do know that some filling stations have water issues,but,with a FASS I would venture to say your need for a WIF light is not a real issue.

The fuel heater deal.....
I have taken my truck up into Northern Quebec,North of Quebec City,to a good friend of mine home for a weekend of snowmobiling.That weekend it was -20F with a wind chill of at or near -40F and had me wondering why I wanted to even go outside let alone ride a sled.I did have my truck plugged in all weekend long and had no fuel heater at all but I did load it up with Stanadyne and Power Service before crossing at Lacolle,PQ going into Quebec.I was worried what would happen and if I would have fuel issues but when I started her Sunday to come home it ripped and snorted but lit off and got me back to a warmer climate.I had confidence in my FASS before I left and really do now as I know it will handle whatever I need it to.Could I have gelled up up there,certainly I will not deny that,but their great product and some quality additives keep her free and running.

The 12v style heaters I have done for the 2 24v guys down here,who are as nervous as anything,were easy to install.Trim off the factory wiring plugs of both,find a place to mount your heater where your comfortable with it.Route the return fuel through it,lengthen the wiring to where the heater is located and make sure you solder the wires and shrink wrap them,do not use crimp connectors.It will heat your fuel going back to the tank as needed so that its warm coming back frontwards........Andy
