Default fuel system

okay so i just bought a new truck. the guy kinda did it backwards in the build butwhats done to it is in my signature. so my question is:

what DV's do i have and should i upgrade them? and if so to what?
Also what lift pump should i use?and what GPH?
and how hard is it to replace a seal on the turbo shaft, exhaust side??
and what fuel plate should i use with this setuP? or should i just leave it out?

thanks in advaced!

Toss the 370 marine injectors and get a better set with the correct spray angle.

the 370's are old school cheap hp that smoke/haze

does it run out of fuel on the top end? no need to spend the money on a lift pump
i made 684.47hp on a stock fuel system

as far as what DV's you have, you need to pull one out and look at the number on the top and go from there

the turbo seal is easy just get a reseal kit and have fun
