I like the FASS I system better because you don't have to worry about standing on your head to change the filter anymore. I am not sure about the filters being exposed to salt and such on your frame rail, but it sure will be easy to change. And with the 3/8 line running to your vp you will never have to worry about restrictions in the line.

 

The FASS is NOT a direct plug and play for the OEM lift pump. The OEM pump is on the engine on the drivers side down low. The FASS replaces it, yes, but is mounted on a custom bracket (included) on the underside of the bed. You have to plumb the lines and wiring to it yourself. There are supposedly good instructions and tons of guys have done it so it isn't difficult. But it sounded like you may have not gotten a clear answer to your question. Just making sure.

 

Keep in mind that DC may void the VP warranty if you put in a FASS. We all know the FASS pump is superior in every way to anything Dodge offers. But it's hit or miss on the VP. Some die regardless of fuel pressure. My truck had it's VP replaced at 45K. I didn't own it then and don't know if a bad LP killed it or not. It's something to be aware of because a replacement VP on your dime is $$$$.

 

plow: I know i dont need it for the truck i have, but i'm hopefully going to go get an 01 2500 ctd next week. I just wanted some opinions on the fass and how much it cost. Will the stock filtration system be ok or do i need to get the FASS l? thanks

 

The stock filter will work, but the lines aren't as big and this will cause some restrictions. But the stock filter system will work. And the instructions are alright, not the best but they do.

 

can u put 3/8" between the vp and filter? Hard or rubber lines? Thanks

 

torque6,

Yes, you can replumb the line between the filter and the VP with 3/8" fuel hose. Many have done this and there are lots of fuel line solutions that include this. If you are going to get a FASS II and plumb it from the tank to the FF, then it probably makes sense to upgrade the hose from the FF to the VP as well. I have not yet, but am planning on it.

Just need a couple fittings and some good diesel fuel hose. You can also get an inline fitting to connect your fuel pressure gauge to. That is what I plan on doing when I get around to it.

Of note, there is a pretty long thread going on over on the other website talking about cooling the fuel before it enters the VP. They use a standard transmission cooler of appropriate size with 3/8" connections. Seems to really work well at cooling the fuel. If you do this, it will obviously require a longer run of fuel hose between the FF and the VP.

thanks for the info CORed

 

Why would you want to cool the fuel? Do you get more power out of it when it is cooler?

 

Farmer Dave,

Now that is a very big question that some guys on the TDR are trying to find out in an objective fashion. I'm just following the thread. I could give you a short synopsis, but the thread itself will be your best bet. There have been several approaches / ideas presented and my personal favorite so far is a cooler between the FF and the VP44. But I'm still thinking about it.

Check it out...
