Billet Fuel Rails
1999-2004 Lightning, Supercharged Harley Davidson F150
The Metco Motorsports fuel rails for the Lightning & Harley Davidson F150 are precision machined from billet aluminum, not commonly available extruded rail stock like other fuel rail kits. Because our rails are CNC-machined from solid billet, we were able to design them with the largest internal diameter available for this application at 11/16". The benefit of this larger ID is a greater fuel reserve at the injectors, which provides greater fuel pressure stability and reduces the possibility of a momentary lean condition when throttle position changes abruptly.
The rails are clear-anodized for long lasting surface protection, and precision-bent stainless steel mounting brackets with stainless fasteners are included to attach the rails to the OEM mounting points. A 1/8" NPT port is located at the front top side of each rail to serve as either an attachment point for a fuel pressure gauge or a fuel source for a nitrous system. Two stainless steel plugs (not shown) are included to seal any unused port.
Note: As shipped, the Metco Motorsports fuel rail kit requires the user to supply the necessary fittings and adapters to mate the rails with the vehicle's fuel system. Our fuel rails have 3/4-16 (also referred to as 8AN straight-thread) female threads in the ends, and use standard ORB-style fittings.
