HFCM question

the HFCM or Horizontal fuel condtioning module is that the lift pump? if so how hard is it to rip it out and install a FASS.

PSD's don't technically have a lift pump. Common rail setups like cummins and Dmax's have lift pumps providing low pressure, high volume fuel to their CP3 injection pumps. A fass is a bolt on bypass system for our HCFM's, it goes right around it and ties in to the factory fuel lines. An airdog, like mine is a "helper" pump supplying hi volume, low pressure fuel to the HCFM. They're not horribly tough to install, the biggest pain in the azz is dropping the tank for the new fuel pickup line. So to sum it up, the fass is a stand alone fuel pump, the air dog is a helper.... I've also heard airdog is coming out with a stand alone system pretty soon too. Reason I went with the airdog instead of FASS is I've heard of too many pump failures with FASS, one of which I've seen personally. The factory HCFM will supply stock or slightly larger sticks all day with the addition of the airdog and a reg. return fuel system. There is also the option of adding a Raptor pump in place of the factory HCFM if you can't keep the pressure to bigger injectors.
