FiTech EFI system

Thanks for checking with them, I don't have time to call them today.

Ok, Here's the deal, right from Fitech.

The spring is not for bypass purposes, its just to secure the filter. And the arrow is to be followed regardless of diagram…

The frame rail sketch is correct
The FCC sketch (at the time of this post) is incorrect

The arrow on the canister is to be followed, and pointing at the TB.

The spring is NOT a bypass....follow the arrow. as i'm sure 99% of you have.
