The VP44 will be fine if it never goes below 5 psi and never more then 20 psi. Depending on who you talk to this may vary 1 or 2 psi in any direction.

I'm pretty sure you can adjust the Air Dog or FASS to operate at your desired pressure.

That depends on who you talk to. Personally I have mine set up to hold 18psi at all times.

my fass 150 gph idles at 16 psi and under full throttle it drops to 12-13 when ive got my edge turned up. if i were you, id look at getting the new adjustable one from fass, you can adjust that thing anywhere from 15 to 45 psi!

yeah there is a way to convert, you have to change your front gear cover from a 12 valve get custom injector lines made, and some people say you'll be alright with with your original injectors but its better to have at least 90's or you'll pop your injector lines, i also think you have to get the gear from the 12 valve to run the pump, oh yeah and dont forget the pump. theres probably some things im forgetting but that short of it
