Ok, I started looking closer at my engine and there is a blue cylinder...I think it is something with the fuel but Im not sure. Anyone that can tell me what this is, that would be great.

Also, why does the line I have circled go into the fire wall?

 

the blue is your FPR (fuel pressure regulator) someone has replaced the factory on it appears

as far as the hose, i have seen some poeple tap into that line for a boost gauge, do you have
a boost gauge?

 

it is ur fuel pressure regulator, it is aftermarket and i dont know y the lines go into the firewall

 

no boost gauge that i know of... i will follow up the hose one of these days and see where it ends.
The car also has a greddy turbo timer hooked up, but the inisde controller is gone...so i have some stuff to sort through...
