The stock fuel rails are fine for lower power levels but as horse power increases, more fuel is needed and the stock fuel system is not up to par.

These were designed to provide the largest possible fuel delivery and fit perfect (OEM fitment). Machined from billet 6061 aluminum and anodized black. To provide all this fuel is a 5/8" diameter through hole and threads for -8 O-Ring Boss fittings. Use the supplied allen head bolts or stock hex head bolts.
