My dad workd on allisons for almost 18 years and he was saying something about a primary and secondary fuel filter system.....i was wondering if anyone knew anything about them or where i could read up on them?

 

Jake knows ALL ABOUT the FASS system..that is what I believe I am putting on my tomarrow thanks to him! They run about 600 to 700 for the whole system with filters...

 

On a lot of the big rigs they run two fuel filters first a water seperator, then a fuel filter. First the fuel goes into the water seperator wich seperates water from the fuel. The seperator also has a about a 100micron mesh inside to filter out the big particles. Thenfuel goes through theprimary filter. This has about a 10micron filter rating. And on some semi's they run another filter after this to get down to a 3micron rating. You can get a FASS fuel system for your truck that will have the water seperator and a filter. Its a great setup, I love mine. You can get filters for it to filter down to 3microns compared to the 8micron stock filter.

 

would you like to suggest where i can look them up and myabe get my greedy clutches on one

 

If not what Jake mentioned... the only filters our trucks have is the stock fuel filter and a screen in the tank.

You can get a walbro setup with a big line kit and 2 mircon filter. Instead of replacing the water separator like the FASS does, you can contiune to use your stock fuel filter / water separator / fuel heater with a 7 microns filter. It doesn't cost as much and is much easier to repair on the road if necessary.

Do not get me worng... the FASS is also a nice setup :-) don't want to get hammered about detering from anothers suggestion ;-O

 

here is what jake told me a while back!
great place!

"I got a FASS lift pump. These guys sell itwww.dieselpp.comHigh quality kit, mayfair did an install writeup somewheres on here"

 

I know it doesn't get THAT cold in Asheville but, it does get cold. Keep that in mind when you get the FASS. It doesn't have a fuel heater and you may have cold start trouble.

 

dang to tell you the truch i didnt even think about that...i should do some more research..does the stock one have a heater? and what other systems are there for the cooler part of the region?

 

ok here is what i have found so far for the FASS system i just need help now fiding the right one. Jake i didnt know if u could help on this. here is a site i found

well, I stated what I said wrong. You'll still have your intake heater so you shouldn't have a starting problem. Ther fuel heater will help gelling though. Like I said.... you "may" have a problem but, it's not realy likely. Plenty of guys are running the FASS in the north.

This kit is an option for you ... very easily installed...
