I want to upgrade my fuel system. I can buy the FASS II for $350 and it seems to come with all the fittings and fuel lines. If I buy a Holly Blue plus Safty shut off switch and Painless wireing kit the cost is $160 but that does not include any additional fittings or lines I may need.

If I go with the Holley set up do I need a scotty mass fuel system?, do I need it if I go with the FASSII. If I put the fittings together myself does anyone have part numbers from Summit racing?

 

Don't worry about the saftey shut off switch or painless kit. You don't need them. To wire it, run a 30 amp relay that is triggered off of the factory lift pump harness. To plumb it, you need some 3/8" ID fuel line that can handle diesel (only about 15psi). Some 1/2" or 3/8" NPT fittings to go into the holley (it will say on the side of the box) and I recommend getting scotty's max flow kit for the rest of it. The holley's are rebuildable and you can pick them up at any advance auto parts store.

 

The FASS II comes with upgraded lines from the tank all the way to the fuel filter input. I have a short bed so I had a couple of feet left over, enough to go from the fuel filter to the vp44, but I did have to get a few fitting to make it work. The FASS II is also rebuildable, has a 4 year warranty. Got mine from Rip at Source Automotive. Would I buy the FASS II again, you betcha! Was on my third lp and constantly check the fp gauge. Still check it, old habits are hard to break, but this thing is rock solid. Easy install, worth every penny. No hard start problems either.

Thats easy, Holley Blue. The FASS is grossly overpriced and has obtained 'cult' status in my personal opinion. Go with a Holley blue and if you have any friends who work in a power station, refinery, or petro-chem facility, get 1/2" sawagelock tubing and fittings from them to complete the install for the perfect professional job. If not, fuel line hose is just fine really, just not a clean and proff looking.

If you want to compare the nuts of it, what are the fuel flow differences between the two at 15 psi of line pressure? Does anyone know?

 

Go with the FASS 2, its a nice setup.

 

FASS

 

Holley blue is 110 GPH free flow and 77 GPH at 10 Psi.

 

DPP has two FASS units one will provide 95g.p.h, and the other will provide 150g.p.h. According to their tech support those figures are at 15 psi.

 

Go with the FASS you won't be sorry. You pay for what you get, with the FASS it is a gear roter pump and a strong motor.

 

I've installed FASS systems, you definately get what you pay for. Anyone who tries to compare price between a single part and an engineered complete system with hardware and instructions needs to pull their head out, IMHO. Kinda like comparing a raw chunk of meat at the butcher shop to a complete steak & lobster dinner where you don't have to cook or clean, the price will be different, but some people like to be catered to, and some like to kill it & grill it themselves!

 

Kill it and grill it yurself baby, and leave the cash for the important power producing parts....

Unless of course you are made of money... then do what you want.

Personal opinions aside on where is best to spend your money, I would say it's your call.

"Cult" status of FASS is well deserved. Overbuilt and bullet proof! Complete package for easy install and trouble free fuel delivery for several hundred thousand miles, with minor preventative maintenance.

Lots of Holley blues out there...working well. I hear more problems with them than the FASS but if you don't mind tinkering...could be right for you.

For some of us, downtime is an expensive inconvienence and eliminating one of Dodges weaker links with a long term fix is solid gold. It's also easier to consider the FASS when you get to right it off as a business expense.
I personally consider fuel delivery as a "important power producing part"....but as always...different strokes for different folks!

Note: If you choose FASS...95 gph pump is all you will need, from either model. With a 5 micron filter (factory fliters are 10 microns) I can't pull FP below 13 psi at WOT.
With the Holley...Scottys fuel flow will be important if adding HP later on. Will get you to 450 hp with enough fuel.

FASS II is the way to go. I replaced 3 holley blue pumps in 9 months. The Holleys would only last about 9000 miles.

 

I've got almost 10k on mine. So far so good. My other holley is on my friends truck and has almost 30k on it I believe.
