Fass is really popular so much I have had 3. They suck, I am meticulous about keeping the truck i have up. I have some power in the 550 hp range and the pump just doesnt like to come on without a ban with an F'in hammer. They are not helpful at all, even thought they have 1800 dollars of my money. This is not an unusual case either, do youir research and go with a Holley blue, relocated fitration, and a regulator. The blue looking competitor is made by a family member of the Fass manu. and probably sucks too. Since its all about getting your money, in an Accessory driven aftermarket. Why would they care of customer relations or product quality. They sure do convince you that the Fass is a great product, cause it looks GREAT comin out of the box, But If I have to tighten the God Damn brushes one more Friggin time, I am ripping the pump off the truck, melting it down and Casting a golf ball, then going to the ocean and 3 wood driving into the abyss where it should have gone straight from The UPS guy.
Sound like I am mad a little, yes I am, I dont like top be butt raped for $600 a pop.
Point is your going to have to BUILD your own so you know what is wrong if it goes bad, then you also know how to reapir it, because after all aftermarket parts make you, " Your Own Warranty Station", sound familiar.
Now I think this is the most honest and educated post here, Thanks and I hope this rant helps. Screw FASS. If they had Balls like men they would send me a free FIXED unit. I stand fully behind all the work I do why wont they, Making too much dough may be the reason, too time spending that money on Campers and LCD TVs i guess Huh?
