I cant find the Installation manual for this thing. it would be very appreciated If anyone can post a clear picture or a drawing on how you connect the fuel lines to it. Ive been searching almost all day and been unsuccesful. thanks in advance. it will be used on S4 stock rails.

 

here you go bro

 

Thanks alex youre the man!!!

 

As that diagram indicates, you only use both inlet ports if you are doing the parallel fuel mod described on FC3Spro, which splits the fuel feed into both rails rather than running them in series. IMO this is not necessary (although it could be if you made enormous amounts of power) but it does look cool. I have my fuel lines running in series, just like stock, and I push 20psi on a 60-1 turbo just fine with consistent fuel delivery. That's gotta be around 400rwhp if not more.
