Anyone Using a Airdog II in place of High Pressure Pump??

[t.c.ben]

My High Pressure pump just went out the other day, and instead of getting a fuel lab pump, I'm looking at the Airdog II to work as a lift pump and High pressure pump. I talked to Dennis at ITP and I guess the kit is complete and ready to bolt in. I am going to go with a Reg return kit, and in the future some stg 2 split shots.
So the questions:
Will this setup support 400 hp?
Anyone using one as a High pressure pump? Any problems?
Hows the install? Do you remove the old high pressure pump??


Thanks for the help
