i called the guys at http//:kensperformancesolutions.com they quoted me the FASS 1 with bypass filter system for $589.00 and the Fass 2 pump without the bypass system $359.00. i am ordering the fass 2 because i dont want to bypass my fuel heater and factory equipment and sensors [water in fuel, low fuel, ect].
they have a adaptor plate and everything to keep all your factory set up for the fass 1 but i saw no need for it.
good luck keeeep on truck'n!
there are basicly 3 type's of pumps for these trucks the factorys being carter style pumps(with the exception of the in tank pumps) some companys have kits to add a secondary pump to aid the factory pump, bd deisel adds a second carter pump, bullydog puts a holley black pump as a secondary but either way u need a good factory plus the secondary, that said then you have the billet pumps like the airdog or fass pumps they dont need a secondary and the fass with the filter kit has a fuel heater in it 1 filter is a fuel water sepeater and has better main filter than the factory uses without airatting the fuel that can happen with the factory pump as well when the fass system put in u only have to change the filters every other oilchange and u take the factory fuel filter and pump out so it cleans up the eingine bay so when u put new parts on or servise or one day when u have to work on the truck(if that ever happens) be less in the way to hit your nuckles on and for price say 250 for new factory lift pump 250 for secondary or 600 for full aftermarket that cleans up under hood and filters better all three systems will support all the power u want to put out 600+hp the choice is yours just putting the options out there with what the diffreces are hope i didt confuse u or miss anything

The FASS, Airdog, and RASP are actual kits for upgrading over the stock LP...the BD (another OEM type pump) and bullydog (a gasser pump) kits I do not consider upgrades, but band-aids.
The FASS and Airdog are very similar (one's the father's company, the other is the son's company). Both are electric pump with filters...I personally went with the FASS because of price, following of buyers, and filter selection.
The FASS II is just a FASS pump, without filters...and after seeing the crap my FASS catches, I wouldn't trust the factory filter with the FASS II pushing.
And as for the heater, I have ran in -20* weather with no fuel heater...think about it...if it is that cold, it will gel in the lines from the tank (way before it reaches your heater)...I simply run fuel antigel at every tank.
The RASP is a mechanical pump that is mounted under the front of the oil pan...it is by far the most complex and still relies on the OEM pump to start.
