Clean looking billet fuel rails are designed to work with truck height LSx injectors (LM7, LQ4, LQ9). Made to use standard -8 ORB fittings. Must use high quality fittings. Cheap knockoff brands have been seen to have poor fitment.
Mounting Bosses on the supercharger are not consistently machined. We have integrated slotted holes to allow adjustment so you can have a perfect fit.
