Why you want a FASS...

[steved]

About a 1/4 tsp of sand in a single tank of fuel... Hope these are viewable...

And too add:



Drained the filter as I put this fuel in (was below a 1/4 tank, so it should have stirred everything up already), filter was clean. Ran the now full tank to 1/4 tank... and drained this crap out.



This is from a single tank of fuel! From the Sunoco Service Plaza on the PA Turnpike at MM305 EB.

Are you going to take that sample to the place you got the fuel from and show them I would think they would stepping all over themselves to correct a bad problem

 

[steved]

The monkeys behind the desk don't care. . they were like "oh, that's neat... "



So, I doubt it would do much good... since I run that road everyday, I make sure that the two times I'm on it that the truck drivers know about it.

Precisely why you want a tight filter the very first thing in your fuel system BEFORE anything else and then recirculate the heck out of your fuel volume.

I know this little incident has been (and should be) a wake up for a lot of other FASS owners that are not checking there filters like they should... one guy reported he filled a 3# coffee can about 1/3 full of water and dirt out of his FASS screen... first time he had drained it since he installed it in Nov 05.

Just thinking... is this a possible reason for why some have NO problems with lift pumps and others have constant problems? I have bought a few BAD tanks of fuel over the years myself... always when on the road and stopping where I found fuel at a good price. However, when I change my fuel filters, I usually have NOTHING in the filter canister! I guess I am getting pretty clean fuel most of the time... and I am getting good service out of the original lift pumps.

I feel this might be a really good reason people have OEM LPs that last for 150k, while some can't get even 50k out of one. A OEM LP is grinding all this junk up before it gets filtered...



You might not be finding anything with the OEM pump because it doesn't have the lift the FASS does... the FASS is like comparing a industrial vacuum cleaner to someone sucking through a straw (the OEM LP).



Another posibility is the OEM LP is grinding the particals up fine enough they actually hang in the filter... I know in all my trucks (over 600k miles) I never found much dirt or much water when changing filters... I have found more water and dirt using the FASS in 15k that those 600k before.



Convinces me that it works.

Stuff like this makes me want to make a "pop-in/out" screen/sock like on aircraft to stop the big crud at the filler neck. Hey you guys with the Aftermarket diesel shops, Here's your next great idea for your accy racks------------RJ

Tank filler tube, tank, fuel cannister, fuel feed line, RACOR 690T, rest of the fuel system (RASP, VP44, fuel coolers).



Sort of like,



You are out in the bondocks camping, need water to drink, but you carry "extra" water you KNOW is clean.



You are out in the bondocks camping, need water to drink (and you prefer not catching something pretty nasty) but do not have "extra" water, you filter it, clean it BEFORE you drink it.



You are out in the boondocks and need Diesel for a $ xx,xxx truck (and you prefer not to do something pretty nasty to YOUR engine), but not sure of the condition fo the fuel, you filter it, clean it BEFORE you use it.

Steved,



You mean the OEM fuel filter system did not catch any debris in 600k, and a vastly superior FASS system caught debris in 15k? Surprised? But instead of guys cleaning up this mess of a fuel system, they throw new pumps, VP44's etc at it to "fix it". I have NO doubt you are right, the problem starts at the filler neck.



Riverside,



1. Carry your own extra fuel (pre cleaned) in jerry cans for use,

2. Pump "new" fuel into a bed tank, then clean it (water & particulates) then put it into the OEM tank for use.

3. Clean the fuel as soon as you possibly can after it comes out of the tank and realize that you probably have crud IN the tank and live with that.

No, what I was saying is that I never saw this much garbage in the OEM filter housing in 600k miles on 4 different trucks. Maybe the FASS is a better system, maybe the factory system doesn't have enough suction to pull the garbage out of the tank? Maybe the OEM lift pump is grinding all the garbage up to the point it sticks in the filter and doesn't settle out... I don't know, but to find the FASS prefilter catching all this stuff that I never saw in the OEM filter makes me wonder...



And just to clarify, I wasn't saying the OEM system doesn't work, just noting what I have experienced.

When I drove rig on the big road, fuel from Pilot, T/A, Petro, 76, and a hundred other one only truck port fuels I always held as suspect. As the saying goes "Life Happens". That's how you live and learn. ------RJ
