I was only getting 18 mpg so I looked under the hood to change filters and such, well my fuel press guage says 4 psi at idle, filter change and it still says 4
I just spent 3k for lift and injector pump less then a year ago
So I say to myself "Self, stop being a cheapskate and get FASS-ed". I got my order in the day before a price hike, and the guy says he's ****** because the only reason he can see to raise the price is because they sell every one that comes off the line and have a 2 - 3 week backorder.
Oh well, I'll wait for it to come in.

 

If you buy the the FASS and supply it with the stock fuel module and stock lines you'll toast it to.There only two ways to improve the supply side to the FASS.(1) plumb a much bigger fuel line to the bottom of the tank,problem with this setup is when the tank is low, around a 1/3 tank, and the fuel sloshes you will pull air.(2)The other way is to install Mopars up dated fuel module to supply your FASS,You will net over 20psi of solid fuel this way.

 

How do you get Mopars updated fuel module? How much do they cost? Are they hard to install? Is it worth all the hassle to get one?

 

I put a hole in the bottom of my fuel tank (as have a few others) and never looked back. I only have about 30k miles on the setup but see no signs of failure, 10 PSI at WOT. Improved mileage of course too. I didn't do 1/2", just 3/8" and this is plenty. For a power house I guess I would use 1/2 or -8 AN.

There's a PN for a -6 an bulkhead fitting at the bottom of this page. I would not do it if you are worried about ground clearance though.

I ordered a FASS fuel system yesterday online. Checking on the status it has not shipped yet so I called to verify they had them in stock. They need to check and will call me back to confirm. I was unaware of needing to replace the pick up module with an updated one for this sytem to function propery. Guess I need to see my friendly Dodge Dealer, so happens we are working on a new dealership building for him at this time.

If they do confirm in stock and shipping I will post where I ordered it from. Give you the option of not waiting 2 - 3 weeks. Cost here was or should I say is $599. I also saw one listed in the classifieds here. Not sure if he still has it but not marked as sold yet.

Good Luck with your truck
