If located elsewhere, a custom hose length is necessary. “Hose length from vacuum block to fuel pressure regulator is based upon the regulator being positioned behind the driver strut tower. Refer to picture. If your fuel pressure regulator setup is different then a custom hose length is necessary.

Locate Vacuum Block and place against plastic fire wall area. (Refer to photos.) Find desired location similar to example photo, and mark the holes.
